ON THE DISEASES OF DOGS.

unusually prevalent; and it is asserted by those who had the oppor- 
tunity of observing it, that the rarefaction and heat of the atmo- 
sphere rendered it unusually malignant. 
According to some authors, this disease has not long been known 
in Europe, and, in fact, it was never observed before the middle of 
the last century. Some maintain that it was imported into France 
from England in 1769, whereas, it is well known that in March 
1714 it reigned as an epizootic in all our western provinces, and 
was then complicated with gangrenous angina. Probably they have 
been mistaken, and meant to say that it was introduced into 
England from the Continent about that time : such, at least, is the 
opinion of the celebrated Jenner. 
Many have conjectured that the maladie in dogs was a disease 
not unknown to the ancients, and they termed it angina ; but if we 
attentively examine the symptoms as they are detailed by Aris- 
totle, Elien, and other authors who have bequeathed to us their 
observations on the canine race, we shall readily perceive that the 
maladie, or the disease known to us by that name, was unknown 
to them, or at least is never mentioned. 
This disease has occupied the attention of several distinguished 
authors. It has been treated of in sporting, agricultural, and ve- 
terinary works. Several physicians have mentioned it, among 
whom are some in England. Dr. Jenner, in the first volume of 
his Treatise on Medicine and Surgery, has traced out a table rela- 
tive to this affection, sufficiently clear for general description, but 
far too limited to become of any practical utility. This cele- 
brated author was induced to notice the subject, from his belief 
that vaccination would preserve dogs from la maladie, in the same 
way that it guarantees the human being against the small-pox. 
Unfortunately, experience has proved that his hopes were without 
foundation. Inoculation will not preserve dogs from la maladie , 
or cattle from le clavelie. 
This disease, either under the form of an epizootic or an en- 
zootic, commits great ravages among dogs in towns and cities, while 
those in country places usually escape. Sometimes it is found to be 
most prevalent during certain seasons, or under certain forms, and 
with peculiar complications. When in its simple state it is not 
so severe or dangerous, and some dogs are but slightly affected by 
it. Those that suffer most are the dogs most valued, petted, and 
nursed, or, in other words, those the farthest removed from a state 
of nature. 
A general survey of" La maladie.” — From the various opinions 
and imperfect data which alone we have to guide us, it is impossible 
to form any very exact idea of the actual nature of this disease 
in dogs ; but several of the Professors at our veterinary schools
