DR. MARTIN BARRY ON THE CORPUSCLES OF THE BLOOD.

to Ttyo^ and filled with red blood. One of the minutest is seen at «. 
The corpuscles in it were pressed into irregular forms, a, a. Some of 
the same vessels, in outline. (3. Corpuscle of the blood, filled with 
young corpuscles ; these being mere discs, elliptical, and differing from 
other discs only in being redder, y. Outline of two of the same parent- 
corpuscles, which were filled, in like manner, with young corpuscles ; 
their membranes shrivelled. S. Parent-corpuscles of the blood, rup- 
tured, and from which young corpuscles were escaping. Some of the 
latter were still elliptical ; while others had become round, but con- 
tinued flat. e. Young blood-corpuscles, larger than those at 
PLATE XXIV. 
Fig. 142. Ox; foetus of ten inches. From the posterior surface of the crystalline 
lens. Vessels here radiated from central trunks, towards the margin 
of the lens. On the left hand in the figure, are three corpuscles having 
the appearance of much altered corpuscles of the blood. A few blood- 
corpuscles have been represented in the portion of vessel figured. It 
contained many not here shown. Most of the corpuscles figured, as 
well as the vessel itself, are in outline, a. Young blood-corpuscles, 
still elliptical, mere discs, and red. (3 . Blood-corpuscle in nearly the 
usual state, y. Form altered, but the corpuscle still quite red. c>. Blood- 
corpuscles dividing into discs, and of a paler red. s. This division of 
the blood-corpuscle into discs, has proceeded farther ; and the effects are 
seen of the same process as that which forms cellular tissue (par. 134.). 
Pale discs, derived from blood-corpuscles. >j. Corpuscle having the 
appearance of an altered corpuscle of the blood. It consisted for the 
most part of pale red discs. Two of the discs presented by this cor- 
puscle, were of a deeper red, and had a darker outline. These occu- 
pied the situation of the original orifice, and afford a remarkable in- 
stance of the identity of the process effecting changes in corpuscles, 
having the same appearance as blood-corpuscles, with that producing 
the first alterations, post coition, in the mammiferous ovum ; and also 
of the similarity between the changes producing pus-globules, and 
some other objects. &. Corpuscle, having the appearance of a blood- 
corpuscle very much enlarged. It was colourless and brilliantly pel- 
lucid in the situation of the original orifice ; and at the part surround- 
ing this, the corpuscle was blood-red, presenting indications of the 
formation there of discs, i. Similar state of a corpuscle of smaller 
size.
