of the horse, struck with the discordance that existed among the 
indications which had been furnished, and the general state of 
the subject, and the apparent integrity of the thoracic organs, we 
had not entreated several of the pupils to assure themselves, by 
an attentive auscultation, that there had not been any error on 
our part. 
This singular fact of the perception of the normal respiratory 
sound on the side of the breast while the lung on that side 
was completely impermeable, may, perhaps, be explained in the 
following way. 
On the left side, the sound lung, which alone respired, caused 
a supplementary sound to be heard, which feebly transmitted it- 
self to the right side, across the lung that had become a solid 
body, and rendered by this transformation a better conductor of 
sound. 
The last two facts come in support of a truth which we have 
often been compelled to demonstrate in our clinical course. 
They prove, among other things, that, in the medical treatment 
of animals, the symptomatic exterior appearance has for its diag- 
nostic the principal value ; a value which the more direct explana- 
tion of the organs ought to tend to confirm, and very rarely to 
weaken. 
Catarrhal Affections of the respiratory Passages . — In the 
compte rendu of the scholastic year (1839-40) we have announced 
the fortunate results that we have obtained in the treatment of 
old catarrhal affections of the chest by the administration of 
emetic tartar in different doses — from four grains to sixteen, and 
even to more. 
We have continued from that period, but especially during the 
course of this year, our clinical experiments on the effects of this 
medicine, and at this period, after three years have passed in ex- 
periments almost always fortunate, we believe that we can safely 
affirm, that the application of emetic tartar is an excellent means 
in the treatment of chronical discharges, which are not of a spe- 
cific nature, or, in other terms, which do not depend on the 
existence of glanders. 
We consider this to be a very important fact as connected with 
veterinary therapeutics. 
In a work that we are preparing and shall shortly publish, we 
shall indicate the doses in which tartarized antimony may be ad- 
ministered, the dangers that sometimes attend its use, and the 
precautions to be taken in order that it may be efficacious, and 
yet not attended with hurtful consequences. 
Intestinal A ffections. — The acute inflammatory diseases of the 
intestinal canal have been in general less serious than usual.
