DR. MARTIN BARRY ON THE CORPUSCLES OF THE BLOOD.

Fig. 112. Ox; foetus of five inches. From the axilla. Three altered corpuscles 
having the same appearance as corpuscles of the blood, a. Many 
bright points seen (par. 134.). (3. Discs now visible, y. Some of the 
discs have enlarged, while others have divided into smaller discs, which 
are coalescing, and thus entering into the formation of the filaments of 
cellular tissue, with the elements in themselves of further perpetuation. 
This corpuscle (y) was bent, from its position in relation to (3. (Tar- 
taric acid.) 
Fig. 113. Ox; foetus of five inches. Altered corpuscle having the same appear- 
ance as a blood-corpuscle, passing into cellular tissue. (Transition 
unequivocal.) From the axilla. (Citric acid.) 
Fig. 114. Rabbit; killed two hours post coitum. From the fimbriated extremity 
of the Fallopian tube. Cellular tissue, forming out of altered corpuscles 
having the same appearance as corpuscles of the blood. 
Fig. 115. Tadpole, about 6"'. Outline of altered corpuscles having the same ap- 
pearance as corpuscles of the blood. They are composed of discs, 
entering into the formation of cellular tissue. All the objects were 
pale red ; and the transition out of corpuscles having the same appear- 
ance as unaltered blood-corpuscles was observed. 
Fig. 116. Tadpole, 5"'. Outline of incipient cellular tissue, composed of discs. It 
was forming out of corpuscles having the same appearance as corpuscles 
of the blood ; and still red. This cellular tissue lay around the spinal 
chord, at a part where the latter had a diameter of ; being appa- 
rently in the course of forming the sheath of the spinal chord, a. The 
outer part of this cellular tissue. (3. A part of the sheath more inter- 
nal; consisting of minuter discs. (Acetic acid.) 
Fig. 116^. Common Fowl ; chick in ovo. Outline of what seemed to be the foun- 
dation of two portions of cartilage in the wing, in an extremely early 
stage (par. 145.). These were composed of very large cells, filled with 
other cells. Colour pale red. The large cells had the appearance of 
altered blood-corpuscles, a. Some of the inner cells are seen ; (3, none 
but the outer cells. The nuclei of the inner cells in a were blood-red, 
and not distinguishable from the young blood-corpuscles fig. 106, lying 
near. (Some of the nuclei of the inner cells in (3 presented the same 
appearance ; while others were larger and paler.) 
Fig. 117* Tadpole, 5'". Portion of the foundation of a cranial vertebra, composed 
of corpuscles having the appearance of more or less altered corpuscles of 
the blood. The round objects are the nuclei of the corpuscles. Two of 
the entire (elliptical) corpuscles are seen of an unaltered shape. All in 
outline except two of the nuclei. All the nuclei filled with discs.
