THE INFLUENCE OF IODINE. 
603 
In the month of July I put on a shoe long at the heels, and 
with the nail-holes near the heels, and I placed felt between it 
and the crust, to preserve the new foot from concussion, and from 
that moment the mule was able to work. In September it went 
to coach work, and it was serviceable for two years, and was 
much less lame than any one would have thought it was possible 
to have been. 
It afterwards died, far from my residence, in consequence of 
some chest disease; and I regret that I was not able to ascer¬ 
tain, by dissection, what new production or kind of stump had 
grown from the smaller pastern. It will, however, always stand 
on record, that after a casualty so serious as the loss of the 
coffin-bone, the mule was able to work more than two years.

CHRONIC ENLARGEMENTS OF THE MAXILLARY 
AND PAROTID GLANDS, REDUCED BY THE USE 
OF THE HYDRIODATE OF POTASH. 
By Mr. W. F. Karkeek, V. S., Truro. 
A favourite old horse, the property of a gentleman in the 
neighbourhood of Truro, was, a few months since, placed under 
my care for a chronic enlargement of the maxillary and parotid 
glands. Several blisters had been applied by a farrier, but they 
only increased instead of diminishing the enlargements. The 
disease had existed for two months; the tumours were hard and 
scirrhous, and the submaxillary glands, in having attained the 
greatest size, were as large as moderate sized oranges. 
I administered aperient medicines, and introduced a seton 
over the diseased glands underneath the jaw, which was dressed 
with the strong mercurial ointment. The ointment was likewise 
rubbed on the glands twice a-day. This treatment proved in¬ 
jurious instead of being beneficial. The repeated blistering of 
the farrier aggravated the evil, and I believe that the seton and 
mercurial stimulants did so likewise. 
I now determined to try the effect of iodine. The parts were 
bathed with warm water, and emollient applications were used for 
a day or two, in order to soften the parts; the iodine ointment 
was then applied twice a-day, in the proportions of one drachm 
of the metal to an ounce of lard ; and five grains of iodine were 
administered daily, made into a ball with some powdered gen¬ 
tian and treacle. 
I continued this plan of treatment for three weeks, increasing
