MR. ALCOCK ON THE CHLORIDES 
tions were found on the mucous membrane of the nose and frontal 
sinuses, and in several cases the septum narium was perforated. 
Another circumstance had aggravated the evil. At the side of 
one of the stables was a little court in which the lime for the new 
buildings and usual white-washings was slaked. The alkaline 
vapour penetrated into and filled this stable, and in the course of 
a few days 22 horses, which were previously in perfect health, 
began to refuse their food, to labour under ophthalmia, and to 
exhibit defluxion from the nose, and ulceration of the mouth. 
A cadaverous smell filled the stable, and large portions of separated 
gangrenous membrane were expelled from the nostrils. 
Every attempt to arrest this destructive malady proved abortive, 
until M. Etienne had recourse to the chloride of soda, of the 
antiseptic power of which he had had some previous experience. 
He diluted the solution of the chloride with 24 times its weight of 
water, and bathed the ulcers with it. Frequently on the second 
application they began to assume the appearance of common 
wounds; and farcy tumours, which were fast developing themselves, 
were arrested in their progress. This diluted solution was like¬ 
wise injected into the nostrils. The defluxion rapidly decreased; 
it soon disappeared; and in thirty or thirty-five days the animals 
regained their health, and returned to their work. 
From May, 1827, to April, 1828,195 horses had been attacked 
with these diseases; 30 had been destroyed before the use of the 
chloride was adopted; 30 died aftemards; 88 were perfectly 
cured; 30 were convalescent; and 17 w^ere left under treatment, 
10 of which were apparently doing well. When the injection could 
not reach the whole of the ulcerated surface, the disease, although 
mitigated, slowly pursued its course. On this account he feared 
that seven of those remaining under treatment would be ultimately 
lost. 
In no case, however, was M. Etienne content with the simple 
local application of the chloride. The usual means of constitu¬ 
tionally treating the disease were continued; but these had been 
perfectly ineffectual before the chloride was used, and likewise 
failed when the chloride could not be brought into contact wath 
every diseased surface. 
Here, for the present, we pause. We earnestly recommend the 
work of Mr. Alcock to the diligent perusal of every veterinarian. 
He will derive from it many exceedingly important hints of 
practice. 
That the chloride of lime will prove to us a valuable disinfect ant y 
and should be always at hand, tliere can be no doubt. It is, 
however, simply a disinfectant. It has been applied externally, 
but without any apparent good effect, in mange and grease. It
