Advance Preparation
Note: This lab has many components. Either clearly designate supply areas for each part of the lab, or provide each lab group with its own set of supplies at the outset. The supplies for each part of the exercise are listed separately in case sections of the exercise are omitted. Some equipment is common to several parts of the lab.
1. Set out slides and coverslips. Have compound microscopes available.
2. Observing Diffusion of Dye Through Agar Gel. Set out 0.1M or 3.5% methylene blue solution (Carolina) and 0.1M or 1.6% potassium permanganate solution (Carolina), 1.5% agar plates (12 milliliters of 1.5% agar per plate, one per group), medicine droppers, and millimeter rulers.
3. Observing Diffusion of Dye Through Water (Demonstration). On the morning of the laboratory session, place some crystals of potassium permanganate in the bottom of a 1000-milliliter graduated cylinder Slowly and carefully fill the cylinder to the 1000-milliliter mark with water Record the time at which the demonstration is set up. Set out millimeter rulers.
4. Observing Diffusion and Osmosis Through Nonliving Membranes. For each group, set out four dialysis sacs (WARD’S) or 10-centimeter lengths of dialysis tubing (Carolina), five 250-milliliter beakers, a wax marking pencil, 750 milliliters of distilled water, 20 milliliters of 10% NaCl solution, 20 milliliters of 40% sucrose-Congo red dye solution, 150 milliliters of 40% glucose solution, dropper bottles of Benedict’ s solution (Carolina, or see above), silver nitrate, four test tubes, a test tube rack, test tube holder, small graduated cylinder, a small funnel, hot plate, and balance. Dialysis sacs can be prepared from cut sections of dialysis tubing. Soak dialysis tubing in a beaker of water for about 15 minutes. Once dialysis tubing has been soaked, open it by rubbing it between the thumb and forefinger until the tubing material separates. Tie the ends with fine twine or close with dialysis tubing closures (Carolina). Small Hefty® sandwich bags can also be used to make dialysis bags.
5. Observing Osmometer Results (Demonstration). At the beginning of the laboratory session, set up an osmometer, using a thistle tube and molasses. Fill the expanded end of the thistle tube with molasses and cover it securely with a differentially permeable membrane. Clamp the thistle tube to a stand and put the broad end into a beaker of distilled water. Mark the level of the molasses in the tube and record the time that the osmometer is set up. Set out millimeter rulers.
6. Investigating Diffusion and Osmosis Through Living Membranes
Experiment 1: Deshell eggs 48 to 72 hours before the day of the lab. To deshell eggs: immerse eggs in vinegar. After 24 hours, gently rub eggs under running water to remove shell. If there is any shell remaining, immerse in fresh vinegar. Repeat rubbing under water and immersion in fresh vinegar until all shell has been removed. Give each group 2 deshelled eggs, two 400-ml beakers, 200 ml distilled water, 200 ml 30% sucrose solution, wax markers, paper towels, weight boat, and laboratory balance.
Experiment 2: Give each group 6 microscope slides and coverslips, dropper bottles of distilled water, filter paper, plastic gloves, physiologic saline, 5% NaCl, a vial of animal blood, and medicine droppers (one per student). Set out a basin of 10% bleach, a wash bottle of 10% bleach, and a disposable autoclave bag.

7. Observing the Process of Filtration. Give each group a ring stand with ring clamp and ring attached, a funnel, a piece of filter paper, a beaker, a 10-ml graduated cylinder, 100 ml filtration solution, and a dropper bottle of Lugol’s iodine. Prepare the filtration solution by mixing 100 ml uncooked starch solution, 10 grams copper sulfate, and 10 grams powdered charcoal.
Comments and Pitfalls
1. Caution students to keep careful track of time during the diffusion experiments Lab timers might help. Suggestions for variables include different concentrations of solutions.
2. Dialysis sacs may leak. Check to see that they are tightly sealed.
3. You may substitute Clinitest™ tablets for Benedict’s solution.
4. Silver nitrate will stain and possibly damage clothing. Warn students to be careful.
5. Note that the 40% glucose solution used in sac 1 of the osmosis experiment is not isoosmotic to the 10% NaCl solution in sac 3, so caution students about the types of conclusions they may draw from this experiment. Also, sometimes no glucose will be present in the beaker at the end of the hour You may need to extend the time for this part of the experiment.
6. Emphasize the importance of labeling test tubes and slides.
7. Red blood cells in physiologic saline may begin to crenate as the slide begins to dry out. Encourage students to make their observations quickly If there is still trouble with crenation, use a slightly hypotonic saline solution.
8. Caution students to be careful when pouring starch solution into filter paper so that the solution does not overflow or cause the filter paper to collapse.
Answers to Pre-Lab Quiz (p. 53)
1. diffusion
2. b, it contains more nonpenetrating solute particles than the interior of the cell.
3. d, vesicular transport
4. phagocytosis
5. active
Answers to Activity Questions
Activity 1: Observing Diffusion of Dye Through Agar Gel (pp. 55–56)
6. Potassium permanganate (MW 158) diffused more rapidly than methylene blue (MW 320). The smaller the molecular weight, the faster the rate of diffusion. The dye molecules moved because they possess kinetic energy.
Activity 2: Observing Diffusion of Dye Through Water (p. 56)
4. Potassium permanganate diffuses more rapidly through the water Although the agar gel is largely water, it does contain more solid particles, which hinder free diffusion.
Activity 3: Observing Diffusion and Osmosis Through Nonliving Membranes (pp. 56–58)
5. After 1 hour, sac 1 (originally containing 40% glucose) should have gained weight. Water is moving into the sac by osmosis.
Glucose is still present in the sac, and a small amount of glucose may also be present in the beaker. If the Benedict’s test is positive, glucose was able to pass through the dialysis membrane.
6. There should be no net weight change in sac 2.
Since the concentrations of glucose and water are the same on both sides of the membrane, there is no net movement of water or glucose.

Exercise 5 27
7. Sac 3 will increase in weight, perhaps only by a small amount.
There has been a net movement of water into the sac and the weight of the water was not completely offset by the movement of the NaCl out of the sac.
The solution in beaker 3 reacts with silver nitrate, indicating the presence of chloride in the beaker.
Net dialysis of NaCl occurred.
8. There should be an increase in weight in sac 4.
The water color did not turn pink; the dye was not able to diffuse out of the sac.
The Benedict’s test for sugar was negative. Sucrose did not diffuse from the sac to the beaker
The dye and sucrose are too large to diffuse through the pores in the membrane or their rate of diffusion is too slow given the allowed time.
9. Net osmosis occurred in situations 1, 3, and 4.
Net simple diffusion occurred in situations 1, 3, and 4.
Water molecules are very small, and move quickly down a concentration gradient. Na+ and Cl– in solution behave like slightly larger molecules, but are smaller than glucose molecules, which move slowly, if at all, through the dialysis tubing. (See item 5 in Comments and Pitfalls.) Note: Students may only be able to conclude that Na+ and Cl– in solution and water molecules are small, and glucose, sucrose, and Congo red dye molecules are larger, or that Na+ and Cl– in solution and water and glucose molecules are smaller than sucrose molecules.
The dialysis sac is often compared to the plasma membrane of the cell.
Activity 4: Observing Osmometer Results (p. 58)
Net osmosis, movement of water into the molasses, occurred as shown by the increased distance that the column of water moved.
Activity 5: Investigating Diffusion and Osmosis Through Living Membranes
Experiment 1 (pp. 58–59)
Conclusions: The egg placed in the distilled water gained weight because the egg is hypertonic to the distilled water The egg placed in 30% sucrose solution lost weight because the egg (14% solution) is hypotonic to the 30% sucrose solution. Water moves from the area of higher water concentration into an area of lower water concentration.
Activity 5: Investigating Diffusion and Osmosis Through Living Membranes Experiment 2 (pp. 59–60)
3. The cells begin to shrink and develop a multipointed star shape.
4. When distilled water is added, the cells should begin to revert to their normal shape. Eventually they begin to look very bloated, and finally begin to disappear as their membranes burst open.
Activity 6: Observing the Process of Filtration (p. 60)
3. Passed: starch, copper sulfate, water
Retained: powdered charcoal
The filter paper represents a cell membrane.
The filtration rate was greatest during the first 10-second counting period because the hydrostatic pressure was greater during that period.
The characteristic of the three solutes that determines whether or not they passed through the filter paper is their size in relation to the size of the pores in the filter paper.

The Cell: Transport Mechanisms and Cell Permeability
Choose all answers that apply to questions 1 and 2, and place their letters on the response blanks to the right.
1. Molecular motion a, d
a. reflects the kinetic energy of molecules c. is ordered and predictable
b. reflects the potential energy of molecules d. is random and erratic
2. Velocity of molecular movement b, c
a. is higher in larger molecules d. decreases with increasing temperature
b is lower in larger molecules e. reflects kinetic energy
c. increases with increasing temperature
3. Summarize the results of Activity 3, diffusion and osmosis through nonliving membranes, below. List and explain your observations relative to tests used to identify diffusing substances, and changes in sac weight observed.
Sac 1 containing 40% glucose suspended in distilled water:
Glucose diffused from the sac into the water; using the Benedict’s test indicated the presence of the glucose that passed through the membrane Water moved into the sac by osmosis; sac gained weight.
Sac 2 containing 40% glucose suspended in 40% glucose:
There was no net diffusion of glucose or osmosis because the water concentration on both sides of the membrane was the same. Net movement occurs only when there is a concentration gradient.
Sac 3 containing 10% NaCl suspended in distilled water:
NaCl diffused from the sac into the water; silver nitrate added to the water showed the presence of Cl–. Osmosis caused water to enter the sac because the solution in the sac was hypertonic to the distilled water in the beaker
Sac 4 containing 40% sucrose and Congo red dye suspended in distilled water:
The Congo red dye did not diffuse from the sac into the water; the water in the beaker did not turn red. The sucrose did not diffuse from the sac; upon boiling, some of the sucrose bonds are hydrolyzed, releasing glucose and fructose. Using Benedict’s test then indicates the presence of glucose if sucrose passed through the membrane; the Benedict’s test was negative Water moved into the sac by osmosis; the sac gained weight.

NaCl: a; moves into sac
6. Summarize the results ofActivity 5, Experiment 1 (diffusion and osmosis through living membranes the egg), below. List and explain your observations.
Egg 1 in distilled water: The egg gained weight because the concentration of the egg, 14%, is hypertonic to the water
Water moves by osmosis from an area of higher water concentration into an area of lower water concentration.
Egg 2 in 30% sucrose: The egg lost weight because the concentration of the egg, 14%, is hypotonic to the 30% sucrose solution. Water moves by osmosis from an area of higher water concentration into an area of lower water concentration.

8. Assume you are conducting the experiment illustrated in the next figure. Both hydrochloric acid (HCl) with a molecular weight of about 36.5 and ammonium hydroxide (NH4OH) with a molecular weight of 35 are volatile and easily enter the gaseous state. When they meet, the following reaction will occur:
HCl NH4OH → H2O NH4Cl
Ammonium chloride (NH4Cl) will be deposited on the glass tubing as a smoky precipitate where the two gases meet. Predict which gas will diffuse more quickly and indicate to which end of the tube the smoky precipitate will be closer.
a. The faster-diffusing gas is NH4OH
b The precipitate forms closer to the HCl end.

9. What determines whether a transport process is active or passive? Whether or not the cell must provide ATP for the process; if so, the process is active
10. Characterize membrane transport as fully as possible by choosing all the phrases that apply and inserting their letters on the answer blanks.
Passive processes: a, c, e, f (sometimes) Active processes: b, d, f (sometimes)
a. account for the movement of fats and respiratory gases through the plasma membrane
b explain solute pumping, phagocytosis, and pinocytosis
c. include osmosis, simple diffusion, and filtration
d. may occur against concentration and/or electrical gradients
e. use hydrostatic pressure or molecular energy as the driving force
f. move ions, amino acids, and some sugars across the plasma membrane
11. For the osmometer demonstration (Activity 4), explain why the level of the water column rose during the laboratory session. The thistle tube was immersed in a dialysis sac which, in turn, was immersed in water. Because water will move down its concentration gradient if it is able, water diffused from the beaker into the sac, where its concentration was much lower As a result, the fluid column (molasses and entering water) rose in the thistle tube.

12. Define the following terms.
diffusion: Movement of molecules from a region of their higher concentration to an area where they are in lower concentration.
osmosis: Flow of water through a semipermeable or differentially permeable membrane Water moves from an area of higher water concentration to an area of lower water concentration, from hypotonic (an area of low concentration of nonpenetrating solutes) to hypertonic (an area of higher concentration of nonpenetrating solutes) solution.
simple diffusion: Movement of molecules from a region of their higher concentration to a region of their lower concentration. Its driving force is kinetic energy of the molecules themselves.
filtration: Passage of substances across a membrane from an area of higher hydrostatic pressure to an area of lower hydrostatic pressure
active transport: A transport system that requires that the cell provide ATP. One such system moves substances across the cell membrane attached to a carrier molecule called a solute pump.
phagocytosis: Engulfment of extracellular particles by pseudopod formation. “Cell eating”
fluid-phase endocytosis: Intake of extracellular fluids by vesicle formation. “Cell drinking”

corresponded with the boundary between Cup Field and Purse Field. Definite proof of this has not been obtained, but it will be shown that the St. John’s property must have extended to within a little of this, thus occupying the site of about thirty numbers. Obviously, the houses must have been very scattered. It is also possible that certain buildings were in existence further to the west, towards Little Turnstile, as early as the reign of Edward II.,[13] and certainly the whole of this part of the frontage to High Holborn was covered in the early part of Elizabeth’s reign.
Agas’s map (Plate 1) shows a single line of buildings extending between the two turnstiles, but this is not an adequate representation of the state of affairs in the closing years of the sixteenth century. In order to describe this, so far as the records which have come to light in the course of the investigation for this volume will allow, it will be necessary to go into some detail, but as the point has never before been dealt with, it has been thought desirable to do so. Although the results in some cases fall short of certainty, it is hoped that thereby an idea may be gained of the somewhat complex system of houses, gardens and orchards that existed between High Holborn and the site of Whetstone Park. The accompanying plan will render the description of the properties more easy to follow. It should be understood that the plan is quite a rough one, and intended merely to give a general idea of the situation about the year 1590. The discovery of further records would, no doubt, modify it in certain details.
HIGH HOLBORN, BETWEEN THE TURNSTILES, CIRC. 1590.
Where now is the entrance to Little Turnstile, there then existed an open ditch or sewer. In the Survey of Crown Lands[14] taken in 1650, reference is made to a certain property “scituate and adjoyninge to Lincolnes Inn Fields alias Pursefeild,” being 214 feet long from Purse Field south, to Mr. Lane’s houses on the north, and 22 feet wide, which ground was “heertofore a ditch or comon sewer and filled upp to bee part of the Pursefeild.” Lane’s houses were on the projecting north side of Little Turnstile, and the sewer lay 21 feet to the east of the present line of Gate Street.[15]
In 1560, Lord and Lady Mountjoy sold[16] to Thomas Doughty and Henry Heron “syxtene meses, mesuages or tenementes adioyninge nere together ... scytuate and being in Holborne,” called by the name of Purse Rents, together with six additional gardens. From the inquisition[17] held on the death of Doughty in 1568 it appears that he held eight of the houses and three of the gardens.
Eight years later (1576) Thomas Doughty, junior, sold[18] that part of the property to “Buckharte Cranighe,[19] doctor of physyke.” In the same year Queen Elizabeth granted[20] to John Farnham, one of her gentlemen pensioners, the whole of the combined Doughty and Heron property, increased on the Heron side by two houses, five cottages, three stables and an orchard, none of which are mentioned in the previous deeds. Farnham immediately sold the property afresh to Doughty[21] and Heron.[22] The latter in 1589 sold to [23]Rowland Watson and Thomas Owen, nine houses, which, by the names of the occupiers, can be identified as nine of the ten sold by Farnham, and which are stated to contain in length together on the street side 35½ yards. In 1669 the same property, then consisting of seven houses, was sold[24] by William Watson to Emmanuel College, Cambridge, and is obviously to be identified with the six houses in High Holborn leased by the college in 1800,[25] and described as Nos. 246 to 251, High Holborn. The length of the Holborn frontage of Nos. 246 to 251 accords well with the dimension required (35½ yards), and the identification of these houses with the property sold by Heron to Watson (B on accompanying plan) may be regarded as fairly certain.
In 1592 Heron sold a further portion of his property[26] , the purchaser this time being Anne Carew.[27] This consisted of (i.) six messuages (C on plan) abutting north upon the lands and tenements of Master Watson (i.e. B), and south upon Heron’s garden; (ii.) a
messuage in the occupation of Sir Thomas Gerrard,[28] abutting north on Heron’s garden and south on “the White Hart feilde”, (i.e., Purse Field, which was held with The White Hart); (iii.) the said garden and an orchard[29] lying together and containing three roods, the garden adjoining west on “the lands late Burcharde Crainck,” and the orchard towards the east, abutting on the messuage and garden of William Cook; and (iv.) the messuage and garden of Cook (H on plan) abutting south on Cup Field, on the north on a tenement of Mistress Buck, widow, and east on a garden late of Thomas Raynesford. In the light of (iii.) it is now possible to assign the Doughty property (afterwards Burrard Cranigh) to position A.
Plots A to F are thus roughly settled, but before leaving them it is necessary to trace further the history of F until its development by building. On the death of Anne Carew the property seems to have passed[30] to her son George, afterwards Baron Carew of Clopton and Earl of Totnes, and by him to have been bequeathed to Peter Apsley, grandson of his brother Peter. In 1640, John Apsley sold[31] to Daniel Thelwall and William Byerly, together with other adjacent property, a messuage with an orchard containing half an acre, “scituate over against the said messuage and extending from the way or path there to the feild side,” all formerly in the occupation of John Waldron. Of this William Whetstone held a lease, which he had obtained certainly before 1646[32] , and in 1653 reference is made[33] to “all the newe buildings thereon erected.” It is most probable, therefore, that this was the scene of the building operations described in the Earl of Dorset’s report to the Privy Council on 11th December, 1636, when he complained that “one William Whetstone,” having lately erected five brick houses in Lincoln’s Inn Fields, without proper permission, had “for the better countenanceing of himselfe therein, and for the finishinge and mayntayneing the said buildings, counterfeited his Lopps hand, as also the hand of his Secre , frameing a false lycence,” etc. It having been decided that this was “a presumption of a high nature, and a fraud and offence not fitt to be passed by wthout exemplary punishment,” instructions were given for the demolition of the houses,[34] but it is not known whether this was actually done.
At any rate, Whetstone succeeded in stamping his name on the new thoroughfare which parted the property in High Holborn from that in the adjoining fields, though the western part was at first
known as Phillips Rents. The Phillips in question was perhaps the John Phillips mentioned in a document[35] of 1672, as having lately been in occupation of a piece of land in the rear of Purse Rents, “being southward upon a way [i.e., Whetstone Park] leading from Partridge Alley towarde Great Queene Street.”
Notice must now be taken of another property of Heron, “parcell of the lands of the late dissolved Hospital of St. John of Jerusalem.” In 1586 he sold to John Buck[36] eight houses (seven with gardens attached) and one garden plot, the first house being described as “all that messuage or tenement with a garden and backsyde, now in the tenure, farme or occupacion of one Thomas Raynesford or his assignes.” The position of Raynesford’s messuage and garden is obviously J (see above) and as H is distinctly stated to be bounded on the north by a tenement of Mistress Buck,[37] the Buck property may be assigned to position G.
In October 1583, Heron had sold[38] to Anne Carew five houses with gardens, a garden with a little house, and three other gardens. The only information given as to the position of the property is that it was situated in St. Giles-in-the-Fields. It is, however, possible to locate it approximately. In 1634, Peter Apsley sold[39] to Sir John Banks, the attorney general, “all that messuage or tenement with appurtenances, scituate in High Holborne, in St. Giles, together with the court or yard lying on the south part of the said messuage, and the garden beyond the said court, extending to the feildes lying on the south of the said messuage, as the same is enclosed with a brick wall, and as the said premises were lately heretofore in the occupation of Sir John Cowper, Knt. and Bart. deceased, and formerly in the occupation of Sir Anthony Asheley, Knt. and Bart. deceased.” In 1661 Sir Ralph Banks sold[40] the house to William Goldsborough, and in 1716 Edward Goldsborough assigned[41] the remainder of a lease of 500 years granted in January, 1692, by Grace and Robert Goldsborough in respect of premises described as “all that messuage, tenement or inn, with appurtenances, scituate in High Holborne in St. Giles-in-the-Fields, known by the name of The George, together with a courtyard or backside lying on the south part thereof, and the peice of vacant ground or garden beyond the said court and belonging to the said messuage and extending to a certain street or place there called Whetstones Park, lying on the south side
of the said messuage or inn.” There can be little doubt that the premises are identical with those described in the deed of 1634, and it may therefore be assumed that the Carew property included the site of The George, which a reference to Horwood’s Map of 1819 will show is now occupied by the eastern portion (No. 270) of the Inns of Court Hotel.
This identification is confirmed by the following. Sir Ralph Banks owned two other houses, one behind the other, adjoining Goldsborough’s house on the east, and these Goldsborough bought at the same time as he purchased his own house. In 1663, he sold them to Edmond Newcombe, and in the indenture[42] embodying the transaction they are described as being 40 feet broad and 160 feet long, and bounded on the east by “the house in which Firman now dwelleth.” In June, 1716, a mortgage was effected by Prescott Pennyston and Thomasin, his wife, of two messuages in High Holborn, adjoining the inn called The Unicorn. Thomasin was the daughter and heir of Elizabeth Hollinghurst, formerly Tompson, cousin and devisee of William Firmin. Now Unicorn Yard occupied a position corresponding approximately to the western half of the present No. 274 (the position is well shown on Horwood’s Map, though the numbering does not quite accord with that of the present day), and distant about 58 feet from No. 270. Assuming the two houses to be one behind the other, as was the case in Newcombe’s property, this leaves the 40 feet required for Newcombe’s house, and 18 feet for Firmin’s house, corresponding almost exactly with the old No. 274 shown by Horwood. The Carew property may therefore be assigned definitely to position K with a fixed eastern limit at No. 270. It has not proved possible to determine its frontage towards the west, and perhaps it did not extend as far as Raynesford’s house (J). It is, however, known that it included a tavern called The Three Feathers. [43] It seems a reasonable assumption that this was in the neighbourhood of Feathers Court, shown in Horwood’s Map as occupying much the same position as the present Holborn Place, but entering High Holborn somewhat further east. The Three Feathers would therefore correspond approximately to the present No. 263.
The adjoining properties (L and M) have already been referred to. The house (M) next to The Unicorn was in Elizabeth’s reign in the possession of John Miller, and in 1607 was described as
“all that messuage, cottage, tenement or house with a forge,” in High Holborn, “reaching to a certeyne pasture adjoyninge to Lincolnes Inne on the south syde,” and bounded on the west by the house and land of John Thornton.[44] Beatrice Thornton, widow, is shown in the Subsidy Rolls as far back as 1588 as resident at or near this spot, and this circumstance is undoubtedly to be connected with the name of Thornton’s Alley, which was hereabouts.[45]
The premises (N), which in the early part of the seventeenth century comprised a single inn, The Unicorn, had in 1574 been purchased by Francis Johnson from John and Margaret Cowper, as three messuages and three gardens,[46] and are described in 1626[47] as having been “now longe since converted into one messuage or inn commonly called The Unicorne.” Apparently its use as an inn was of recent date, for in the description of (M), dated 1607, the eastern boundary of that property is said to be “a tenement in the occupation of John Larchin, baker,” and in 1629, when the premises had been re-divided into two, one is said to be[48] “now in the tenure of Mary Larchin, widdowe, and is now used by her as a common inne, and is called by the name or signe of The Unycorne.” The dimensions of the premises are given as 45 feet wide on the north, 40 feet on the south on Lincoln’s Inn Fields, and 156 feet long.
No records of the time of Elizabeth relating to property between The Unicorn and the house at the corner of Great Turnstile have, so far, been discovered. The latter (O), having a frontage to High Holborn of 39 feet, was certainly at the time in the possession of the same John Miller[49] who held the property (M).

The area lying between Great Queen Street, Little Queen Street and Gate Street (the east to west portion of which street was formerly known as Princes Street) was originally a portion of Purse Field, the early history of which has already been detailed.[50]
On 27th May, 1639, William Newton sold to John Fortescue[51] “all that peece or parcell of ground, being part of Pursefeild and the pightells, designed for two messuages to be built thereon by the said John Fortescue, the foundations whereof be now laid.” The ground is described as measuring 50 feet 3 inches from north to south, and 127 feet from east to west. Between the ground and Princes Street (“a way leading upon a backgate of an Inn lately called The Falcon and Greyhound”) lay the houses (or their sites) of Lewis Richard and John Giffard, and a slip of ground afterwards bought by Arthur Newman, having widths of 25 feet, 25 feet and 8½ feet respectively[52] . From these measurements it can be shown that the ground sold to Fortescue was the site of what afterwards became Nos. 3 and 4, Gate Street. The indenture contained, in common with those relating to Richard’s and Giffard’s houses, a provision “that there doth and soe perpetually shall lye open from the front of the said messuage eastward, three score foote of assize, wherein there shall be noe building erected or builded by the said William Newton, his heirs ... or any other person or persons whatsoever, it being the principall motive of the said John Fortescue to purchase the estate and interest aforesaid, to have the said 60 foote in front to lye open for an open place from the front of the building, except 11 foote to be inclosed in before the house, and that there shal be noe buildinges erected at the south-east end of the said open place by the space of 30 foote, to take away the prospect of the greate fielde, otherwise than a fence wall, whether he, the said William Newton or his assignes, keepe the same in his or their owne hands, or doth or doe depart with it to any other.” It was also agreed “that there shall not at any tyme or tymes hereafter be erected or built any manner of
