its function requires it. It is, as I have stated, the inner guard 
of the lungs, and the larynx must undergo a multitude of 
changes of form in order to adapt itself to certain changes in 
the respiratory act, and in order to produce the voice. The voice 
of our patients is strangely limited, compared with that of the 
human being. The same sensibility, therefore, is not required ; 
and nature never gives that which the animal does not need. 
Exposed as our quadruped slaves are to absurd and barbarous 
usage, too great sensibility of any part, and particularly of this, 
would be a curse to the animal. 
Connected, ivith some Symptoms of Rabies .—This decrease of 
sensibility enables us satisfactorily to account for an important 
fact, viz. the true hydrophobia, or dread of water, in rabies in 
the human being—the almost total absence of it in the brute. 
The degree of morbid sensibility generally bears a strict propor¬ 
tion to that which is natural to the animal or the part. To pro¬ 
duce the thousand delicate intonations of the human voice, the 
highest degree of sensibility is given to the larynx; but in¬ 
comparably less will suffice, where the compass and intona¬ 
tions of the voice is so much limited. We can imagine, that in 
the one the morbid irritability may be so great that no fluid 
can pass over the membrane without exciting the most horrible 
spasm ; that the very thought of it shall produce the spasm, and 
that even a current of air, in increased quantity, or of altered 
temperature, passing through the glottis, shall be followed by 
the same horrible consequences ; while in the other, no marked 
effect shall be produced by the same agents. This will be more 
fully discussed when, under the sensorial system, I treat of 
rabies. It is now mentioned incidentally as satisfactorily ac¬ 
counting for the fact, that the principal distinguishing symptom 
of rabies in the human being is wanting in the quadruped.

[The following work, originating in a manner from The Veteri¬ 
narian, and the subject of it again and again discussed in the 
pages of our Journal, claims from us something more than a 
mere formal review. We with pleasure dedicate our leading 
article to its consideration.]
