DR. MARTIN BARRY ON THE CORPUSCLES OF THE BLOOD. 
similar corpuscles, arranging themselves into fibres, and then exhibit- 
ing indications of division into discs still more minute, y. Outline of 
corpuscles of the same kind, arranging themselves into a cellular tissue- 
like object, and at the same time undergoing division into discs. 
(3, y. Blood-red. 
Fig. 7 4. Tadpole of the large Toad of Jersey; about 6"'. a. Young blood-cor- 
puscles ; some of them exhibiting an orifice. Colour, pale red. (3. Young 
blood-corpuscles of a deeper red. 
Fig. 75- Tadpole, about 6"'. Blood-corpuscles ; partly in outline, a. The minute 
red points around the nucleus in this corpuscle exhibited molecular mo- 
tions. jS. Discs are seen in the situation occupied by the minute red 
points in a; these discs pressed into polyhedral forms.

They correspond apparently to the “ lymph-globules,” or “ corpuscles 
of the second form,” of authors, a. The discs are numerous and 
minute. (3. Discs fewer and larger, y. The object in two portions, — 
perhaps a nucleus (eccentric), and an incipient cell ; the nucleus com- 
posed of pale discs, — the surrounding part reddish. Discs were di- 
stinctly visible in this surrounding part also. 
Fig. 77- Water Newt. Outline of blood-corpuscles, some of which were observed 
to contain blood-corpuscles, besides their nucleus. 
Fig. 78. From the same. Objects found with blood-corpuscles, — all in outline 
except one. The latter, much enlarged, is seen to have been filled with, 
or made up of, discs ; which was the case with all the rest. These 
objects appear to correspond to the “lymph-globules” of authors. 
Fig. 79- From the same. Outline of a blood-corpuscle, and of the discs contained 
within it. The central object is the nucleus. (Acetic acid.) 
Fig. 80. From the same. Outline of blood-corpuscles and their nuclei, as seen 
after the addition of an aqueous solution of nitrate of silver. The in- 
terior of one of the nuclei is shown. It was filled with discs, as were 
all the others. 
Fig. 81. From the same. Outline of two blood-corpuscles, as viewed after the ad- 
dition of a solution of corrosive sublimate. The interior of the nuclei 
is shown, a. In the nucleus were discs of about equal size. (3. The 
nucleus presented discs at its central part ; around which there was a 
space, apparently occupied by discs in a more advanced state and 
larger. 
Fig. 82. Green Lizard. Corpuscles of the blood, a. Outline of one of these. 
(3. Two corpuscles, the nuclei of which were composed of discs, y. Cor- 
puscle filled with discs. c$. Disc of the same colour as the corpuscles of 
the blood : perhaps a young corpuscle.
