That the blood of the lamb differs considerably from the 

 blood of the parent sheep, is obvious from the following analyses: 



The maxima, minima, and average numbers quoted above, 

 are sufficient to prove that the blood of different species of ani- 

 mals varies in its composition from that of man and of each 



' Gmelin (Handbuch der theoretischen Chemie, vol. 2, p. 1387) found, in the 

 arterial blood of a dog — water 898, and fibrin 2-09 ; the dried serum contained, 

 albumen 88-3, and salts 11-7 ; the venous blood contained, water 843, and fibrin 2-1 ; 

 the dried residue of the serum consisting of albumen 87-5, and salts 12-5.
