382 LIQUID PARTS OF ANIMALS. 



constituents of the blood in different animals, or to a diversity in 

 the constituents themselves. The few analyses of the blood of 

 inferior animals are not capable of enabling us to decide this 

 point ; but it may be worth while to state here the principal facts 

 which have been ascertained. 



1. Ox blood. Lecanu analyzed the hematosin in ox blood 

 and obtained, 



Carbon, . 66-49 . 65-91 

 Hydrogen, . 5.30 . 5-37 



Azote, J 10-54 . 10-54 



Oxygen, . 11-01 . 11.75 



Iron, . 6-66 . 6-58 



100-00 100-15 



Two analyses of dried ox blood were made in Liebig's laboratory 

 by Messrs Playfair and Bockmann. They obtained, 



Playfair. Bockmann. 



Carbon, if.-u;; 51-950 . 51-965 



Hydrogen, . 7.165 . 7-330 



Azote, . 17-172 17-173 



Oxygen, . 19-295 91-115 



Ashes, . 4-418 . 4-413 



100-000 99-996 



2. Horse's blood. The following table shows the difference in 

 the proportion of water and solid matter in the arterial and ve- 

 nous blood of the horse : 



I. Arterial Blood. 



Water. Solid matter. 



From the aorta, . 783-83 . 216.17 

 From the carotid, . 785-50 214-50 

 II. Venous Blood. 



Water Solid matter. 



795-67 204-32 

 804-55 . 195-45 



According to Magnus 1000 volumes of horse's blood gave 

 47 volumes of carbonic acid, 

 12 volumes of oxygen, 

 7 volumes of azote, 

 while 1000 volumes of calf's blood gave
