In the feetions of the alcyonium you may plainly diflinguith the reticulated elaffic fibres, that enclofe the tranfparent ?tiff gelatinous part, as in the fponges:

to feparate it from the clank fibres ; however, with a little trouble it may be done fufficiently to mince what I have endeavoured to prove, I mean, the great ptoximity there is between the animal life of fponges

and alcyoniums, and confequently that both are animals.

Bea. I conclude, I muft endeavour to remove tome doubts, which Item to have dill relied the generality of curious perfons to account for t the one is, what occafions thofe very large holes that appear
