ANIMAL PATHOLOGY. 
The horse has glanders, farcy, grease, and periodical ophthalmia. 
The mule has rarely, and the ass never has strangles; and both 
of them escape the torture of contracted feet. Cattle, sheep, 
dogs, swine, know not any of these complaints. The human 
being has, peculiar to himself, variola, scarlatina, and syphilis. 
Need we, then, wonder that there should be considerable dissimi¬ 
larity between rabies in the human being and the brute? 
These hydrophobic symptoms in man have been known to 
accompany other diseases, besides rabies. They depend upon 
an irritable state of the fauces and larynx. They depend upon 
the power of imagination. That faculty often imposes strange 
delusions upon us. A gentleman was bitten by his dog. The 
animal immediately disappeared, and could no where be found. 
The owner sufi’ered this to make a fearful impression on his 
mind, and at the expiration of four days he was ill a-bed, and with 
well-marked hydrophobia. His life was despaired of. On the fifth 
day of the disease the dog returned. He was let into his master’s 
chamber. He jumped upon the bed and caressed him as usual, 
and every symptom of hydrophobia disappeared in a moment. 
21ie Difference in the Disease in these beings a very natural one .— 
I used to take more pains than probably were needed to account 
for this difference of symptoms. A few papers on rabies, pub¬ 
lished in the 1st and 2d volume of The.Veteri nari an, were 
collected into a little pamphlet in 1830. To that I beg to refer 
you, only stating now that there is inflammation of the larynx in 
the great majority of cases of rabies both in man and the brute: 
but from the more important function of the larynx in the human 
being it possesses a superior degree of sensibility. It is the prin¬ 
cipal organ of voice, every intonation of which, every expression 
of thought, although partly modified by the mechanism of the 
fauces and the mouth, depends chiefly on the structure and ex¬ 
quisite sensibility of the larynx. The voice of the quadruped is 
infinitely more confined ; and every expression of intelligence 
and feeling is more simple. Besides, in the quadruped, for 
wise and good reasons, a peculiar mechanism is superadded 
to the larynx, by which the ideas and the wishes of the animal 
are chiefly expressed. Great sensibility of the larynx is therefore 
not only unnecessary but would be a nuisance. The comparative 
anatomist and physiologist would expect to find this precise dif¬ 
ference of symptoms in rabies as it attacked the human being 
and the inferior animal. Still there is sufficient identification 
of malady in the involuntary and peculiar howl of the dog; the 
choaking noise attendant on each respiration, and the blush of in¬ 
flammation, more or less intense, which every dissection presents.
