The Canadian journal ; a repertory of industry, science, and art ; and a record of the proceedings of the Canadian Institute. e to Toronto; and here, even, circumstances prevented usworking at it until nearly too late, as the animals died, andalmost immediately decomposed. Prom what we did see,however, there is some reason to conclude that this speciesdiffers from the European animal, not merely in the form ofthe cells, but in the animal itself, which is certainly larger, andappears to possess a much greater number of tentacles. In making microscopical examinations of thin slices of thisPolypidom, we were struck with the appearance of a greatnumber of bodies such as represented at a, and forsome time we necessarily concluded that we were gazing uponthe ova of the Polype, in various stages of developement, asshewn at b and c, in the same figure. The central mass isentirely, and densely dark, while the narrow, somewhat trans-parent margin seen at a, is remarkably cellular, being composedentirely of hexagonal cells, of much regularity in their formand size (d). These cells are again seen in b, at/, where, also,. we see developed six hooks—three at either end; at c, thehooks appear to have attained their maximum examining the specimens by direct light, (as opaque objects),Vol. Ill, No. 9, April, 1855. the C3lls are seen to be continuous over the entire presence of cells ofFers no objection to the animality ofthese bodies, whilst the hooks remind one so forcibly of theovum of Cristatella mucedo, (a fresh water polype) as fi<mredby the late Sir J. G. Dalyell, Bart., Raspail, Cornelius Varley,that it left little doubt these were the indubitable ova ofthe Plumatella, wh<m, presently, several of the mature bodiesappeared, their surface being more or less covered withcorpuscles of starch, as shewn at g. g. in c—this was at e
