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.—Anzmic animals generally exhibit con- 
siderable muscular prostration, with depression of spirits ; 
the mucous membranes are pallid, particularly on the 
gums, and inside the lips, the tongue is also unusually 
white and dry, the extremities are cold, and the limbs 
not unfrequently swollen, and the secretions and ex- 
cretions scanty. 
M. D’Arboa relates the following cases : 
“Two dogs were sent into the hospital of the Veterinary 
School at Lyons. They did not appear to suffer any 
considerable pain. Their skin and the mucous mem- 
branes that were visible had a peculiar appearance. They 
had also comparatively little power over their limbs: so 
little, indeed, that they rested continually on one side, 
without the ability to change their posture. When they 
were placed on their feet their limbs gave way, and they 
fell the moment they were quitted. Notwithstanding 
the care that was taken of them, they died on the second 
day. 
“‘Incisions were made through the skin, but in opening 
them no blood flowed. The vene cave 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
