484 ON THE ACTION OF IODINE AND CHLORINE. 
siderable, and offensive ; appetite impaired, and the animal’s 
condition extremely low. I recommended a trial of the iodide of 
iron, and, indeed, I expressed myself as feeling obliged to them 
if they would give it a fair trial. This they kindly consented to 
do, and commenced by exhibiting it in doses of ten grains twice 
in the day : this quantity was gradually increased to thirty 
grains ; at the same time, at the request of Mr. Salter, a weak 
solution of chlorinated lime was injected up the nostrils, for the 
purpose of correcting the foetor of the discharge. After a few 
doses only of the medicine had been given, a marked change was 
apparent. The appetite was improved, and with it the animaPs 
general appearance ; the ulcers assumed a more healthy aspect, 
and the discharge was less. The amendment continued daily to 
progress ; and at the end of three weeks the discharge from the 
nostrils had entirely ceased ; the ulcers were perfectly healed, the 
animaPs appetite had returned, and his condition was materially 
improved ; indeed, it might almost be said, that no abnormal ap- 
pearance remained, except a little enlargement of the glands : 
but, unfortunately, the animal being of no use to the proprietor, 
he was destroyed. 
Now, I do not wish an impression to rest upon the minds of 
any, that I think the iodide of iron is a specific for glanders, or 
that we have such a thing as a specific for any disease ; or even 
that this related was a case of confirmed glanders ; my only 
object is, to prove that the compounds of iodine are of value, and 
that this, among the rest, posseses much power; perhaps, too, 
it may provoke others to a trial of its merits. 
If I were asked the form in which its administration is to be 
preferred, I should answer, that of solution, combining it with 
an infusion of calumba root and ginger. 
Iodine was given at this institution as far back as 1827. 
Small doses were at first exhibited, and these gradually increased 
until three ounces were given twice during the day. No visible 
effects following this enormous quantity, I wrote against the 
recorded experiment “This agent may be considered of no use 
as an article of the veterinary materia medica.” This I did in 
ignorance ; for I am now firmly convinced, that both it and its 
compounds are of great value ; but, to experience any real good 
from them, they must be given in small portions, and for a long 
period of time. 
The inhalation of chlorine gas diffused through an atmosphere 
containing an excess of watery vapour, I have thought likely to 
prove beneficial in glanders, whether chronic or acute ; also in 
affections of the bronchial passages, accompanied with a foetid 
discharge; but this is merely speculative, and before it can be
