which gives colour to the blood. Stint the supply of this 

 necessary element, and though externally not so per- 

 ceptible in dogs, you withdraw the colouring matter, 

 and obtain the same pallid condition. Again, good 

 nutritious food is just as necessary for the production 

 of pure blood and healthy muscle. We may as well try 

 to build a strong substantial house out of bad material, 

 as expect that blood derived from such a source, and 

 under the circumstances enumerated, will make sound 

 strong muscle. 



Symptoms. — Anemic animals generally exhibit con-

" Incisions were made through the skin, but in opening 

 them no blood flowed. The venae cavae themselves did not 

 contain any — there were only two clots of blood in the 

 cavities of their hearts. One of them, of the size of a 

 small nutmeg, occupied the left ventricle ; the other, which 

 was still smaller, was found at the base of the right 

 ventricle. The chest of one of them contained a small
