fully developed cases, the mouth being slimy and equally 
offensive, and the feces are small, hard, glazed with 
mucus, and emits the same disagreeable odour. The 
end soon comes on. Dulness is followed by insensibility, 
the animal lies stretched on the side, and life gradually 
passes away. Uremia may be due to disease of the 
kidneys, but as a rule it is the result of obscure causes, 
without special disease of those organs. 
Apnoeea.—This is a form of blood-poisoning arising 
from an arrest of the functions of the skin. It is mainly 
due to the use of large quantities of resinous ointments 
and other agents which prevent due transpiration. 
Among horses and sheep the disease is more or less 
prevalent, but in dogs, as the skin is less active, this form 
of disease is not so common.

or Small Pox. 
THE specific diseases of the blood in canine animals 
have received much greater attention in later years, and 
close observation has been rewarded by the recognition 
of various forms from which the system of the dog was 
believed to be practically exempt. This may possibly be 
due to the extension of the causes, the majority of which 
bear close relation to our international relations with 
other countries of the world. They present a wide field 
for study, especially in their relation to the diseases of 
mankind, and in a few years hence the present list may 
be considerably extended and enriched by further dis- 
coveries, removing many difficulties we now experience. 
Anthrax, or Charbon, otherwise coal, derives its
