The testimony and opinions of many able chemists and physiologists go to establish the 
doctrine that there are important differences in venous and arterial blood. The following 
paragraph is a summing up of the differences, as established by careful experiments and 
analyses : u That arterial contains less solid residue generally than venous blood : it con- 
tains less fat, less albumen, hsematin, extractive matters and salts, than venous blood ; and 
also that the blood corpuscles of arterial blood contain less coloring matter than venous”!. 
It must be evident that blood can possess no definite composition; that the blood of two 
individuals must be somewhat dissimilar ; and probably that the period of life, food, etc. 
must particularly modify its composition. It is well established that the condition of the 
organs materially affects it. Food which is intended to impart strength, must be rich in 
vegetable fibrin and albumen. Animals which are worked, or which afford milk, must 
be supplied also with the same materials, with food which contains elements of the compo¬ 
sition of their own flesh. 
The composition of different parts and organs of animals may be stated here, and in this 
connection, from the bearing which the subject has upon the growth and renewal of tissues.
