OISTASLS OF RESPUADIKY FASSAGES AND ORGANS. 121 
thirty zeains 9° odie of potass ia twe tunes of fluid extract of 
resin-weed root: an ocasional cose of go!den seal was given as a 
tonic. The iodide of potass acted on the system as a glandular 
stimulant, and thus increased the power of the ubsorbents and ex- 
crement't*ous vessels, to rid the chest of its fuid contents, while 
the resin-root acted as a diuretic, thereby carrying off some of the 
fluid by way of the kidneys. During the period of the sickness 
of this animal, the resonance of the chest gradua'lv became clear, 
sv that at the end of three weeks not more than a coaple of pints 
of serum remained in the chest. The animal rapidly coavalesced. 
During the treatment of such a case as the above, I usually feed 
the animal liberally on oats and sweet hay ; and, in order to obvi- 
ate constipation, I order an occasional bran-mash. The animal, 
however, may not, at the commencement, have much relish for 
food, but after a few doses of the medicine here recommended have 
been given, the appetite will soon be restored. It will be noticed, 
during the progress of this malady, that the animal does not lie 
down, but stands with the fore-legs widely apart, although, at the 
very commencement of acute pleurisy, the subject will often get 
down, in view of mitigating the lancinating pain from which he 
suffers, in consequence of the distension of the vessels of the pleura. 
Pleurisy sometimes sets in as an accompaniment of influenza, 
which almost always ends in dropsy of the chest ; and as a case ot 
this kind is a good one to place on record, I here introduce one 
from my note-book : 
Pleurisy ending in Dropsy and Death.—The horse, the subject 
of the above-named maladies, was the property of a milkman of 
Chicago. The animal had been previously treated for the prevail- 
ing influenza, accompanied by pleurisy, and had about recovered 
so as to take daily exercise; but finally the owner discovered that 
the horse was suddenly taken with a relapse. Feeling alarmed, 
he procured one pint of linseed oil, with which he drenched the 
animal. Still, the horse rapidly grew worse. At this period, my 
services were sought. On auscultating and percussing the chest, 
I found that the right cavity was occupied by a large quantity of 
water. Dropsical swellings were found in various parts of the 
body, viz.: the sheath, limbs, and region of the pectoral muscles, 
On applying the ear to the trachea, the respiration was of a mucoua 
character, and tubular, showing that the lungs were much diseased. 
The examination revealed the fact that about one-half the left lung
