Diagram II.—a, represents the perfectly formed, ovaland characteristic disc, or globule, of the frog. In the cen- COMMUNICATIONS. 281 tral portion may be seen an oval depression, in the centerof which can be observed the elevation representing thenucleus. The margin is shown to be rounded, smooth andthickened. 6, is like the former in every respect except the centralpapilla is absent. c, a shriveled corpuscle. d, a corpuscle as it would appear set upon its edge. It will be seen from the foregoing explanation that thesebodies do not all possess a nucleus, or central fact, there are in both the human blood and that of thefrog a large proportion, perfect in every other respect, thatdo not possess this peculiarity. Whether this fact is due toan absence of this feature on one of the surfaces of the cor-puscle or to its non-existence in a certain per centage ofcases, I am undetermined. I have, as yet, examined but few pathological one instance, howeve
