DR. MARTIN BARRY ON THE CORPUSCLES OP THE BLOOD. 255 



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 (7) 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; k'xUed 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 &'". 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. j3. A part of the sheath more inter- 

 nal ; consisting of minuter discs. (Acetic acid.) 



Fig. II64. 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.
