BLOOD BIOPLASTS, OR, WHITS BLOOD CORPUSCLES IN VESSELS 

 0? EMBRYO. 







Capillary vessels and small vein from the ovum of the turtle at au early period of development. 

 The vessels are entirely filled with white blood corpuscles, and in some places they were completely 

 distended with them. Developing connective tissue with connective tissue corpuscles, fat cells 

 and perhaps nerve fibres are also seen. To the right of the drawing at a will be observed a very 

 young capillary, the tube of which is not yet wide enough to allow a blood corpuscle to pass 

 through it. X 215 lS6i. p. 216
