RABIES IN THE DOG—SYMPTOMS. 231 
short duration—she became gradually calm and composed, and 
on the following day she was herself again. 
In the course of six-and-twenty years, having had occasion to 
see at least two thousand rabid dogs, I have witnessed something 
like this, half a dozen times or more, in animals sent to my hospital 
after having been bitten, and to be kept there until the time of 
danger w'as past. I have seen the anxious licking of the bitten 
part—the suspicious countenance, the increased irritability, the 
wandering eye—nay, I have heard the very howl; and 1 have 
been assured that rabies was establishing; itself, and that the 
dog would die: but, m less than twelve hours, all had passed 
away, and that animal never afterwards exhibited one symptom 
of rabies. I mention this, not as having any thing unaccountable 
about it, for every animal poison may, in like manner, be introduced 
into the frame in sufficient quantity for awhile to derange the 
system, but not to produce its full and destructive effect, but 
I refer to it as an encouragement to persist in our remedial 
measures, even after the partial development of the disease ; and 
also as a probable explanation of some of those cases in which 
hydrophobia has appeared to yield to medicine. 
Identity of the Disease in Man and the Brute ,—I have stated 
enough to prove the similarity, or rather identity, of the disease 
in these two classes of patients : but I must not forget the hydro¬ 
phobia or dread of water—of invariable occurrence in the human 
being, and but seldom observed in the brute. It is, however, 
occasionally seen in all our quadruped patients. 1 have, de¬ 
scribed it in the dog, the horse, cattle, sheep and swine. The 
difference, then, is in its occasional, instead of its constant exhi¬ 
bition. If, however, it were a symptom constantly observed in 
man, and never found in the dog, would that prove an essential 
difference of disease? Are we to expect that the same symp¬ 
toms shall always accompany the same disorder in every animal ? 
Is not the difference in the same disease, dependent on difference 
of structure and destination, that which makes the study of com¬ 
parative pathology so interesting and so useful ? The inflammatory 
fever of cattle and sheep often runs its course in two or three 
hours. The hoven of cattle is unlike tympanitis in any other 
animal. Indigestion in the horse bears little resemblance to re¬ 
pletion or over-distention of the stomach in other patients. Psora 
or mange in the horse, the dog, and the sheep are exceedingly 
unlike. Affections of the chest, and their symptoms, duration, 
and termination are often extremely dissimilar in the bibed and 
the quadruped, and in different quadrupeds. 
Not only do the symptoms of disease vary, but some animals 
are subject to certain maladies from which others are exempt.
