OBSERVATIONS. " I have learned that want of Observation is a sad and very c o m m o n infirmity of h u m a n nature, there being h u n d r e d s of persons before whose eyes t h e m o s t w o n d e r f u l things are passing every day a n d who, nevertheless, are totally ignorant of t h e m . "

—Ballantyne's Coral Is., cap. xiv. Late Red Crag AT DOVERCOURT.—They are digging a fourteenfoot trench for a sewer close to this house, and have come across strata of various-coloured Clay and the Crag, from which I send you the enclosed fragmentary Shells for identification : are they from the sea-bottom, above which we are pretty high nowadays, or a lake ? Geology seems such a deep study that I find the few books I have upon the subject hard to widerstand.—Mrs. BLANCHE GRAVES, The Lodge, Dovercourt; 18 June. [Material received consists of numerous comminuted Molluscan shells, mainly of the species Mya arenaria, L., showing it to be of late in the Red Crag period (possibly even from the Chillesford Bed), with a few scraps of the Scallop Pecten opercularis, L. and one bit of both Mactra stultorum, L., and Cardita senilis, Lam., of older deposit. The sole other Animals present are two bits of Barnacles-shell Baianus balanoides, L., a kind still living profusely along the Suffolk coast. Dovercourt is mainly on London Clay, but the later Crag may remam upon it anywhere between Felixstow and Waltonon-Naze.—Ed.], FOSSILS FROM THE HOLTON " Gun-shot" Grave!.—Mr. J. F . Sampson has for some time been in the habit of retaining any fossils that appeared to him interesting or peculiar among the Gravel at Holton near Haiesworth, and this year the Society had the pleasure of naming them for him.
