 BLOOD OF VERTEBRATE ANIMALS IN ITS NORMAL CONDITION. 



Blood of Fishes. 



1. Tri/gon sabina, hes. (female). Stingray. Aug. 14, 1855. 



The appearance of the left uterus of this Ray, indicated that it had been 

 delivered of young ones only a short time before its capture. 



The appearance of the viscera and impregnated uterus of one of these fishes is 

 represented in Fig. 19. 



The portion of blood first drawn coagulated, in a few moments, into a dense, 

 firm clot, which, in the course of an hour, commenced to dissolve, and in two 

 hours, entirely disappeared. Another portion of blood, drawn subsequently, coagu- 

 lated imperfectly, allowing the majority of the blood-corpuscles to settle to the 

 bottom of the vessel, and, in the course of half an hour, the fibrin was completely 



dissolved.
