ON THE USE OF IODINE IN FARCY. 
By J. B. Hall, M.R.C.V.S., Y.S. Royal Artillery. 
On the 19th of August last a black troop-horse, stationed 
at Northampton, was reported to me by the farrier as being 
lame and having a swelled leg. I examined it, and more than 
suspected it to be farcy. The animal was therefore placed in 
an infirmaiy box, away from the other horses, and allowed to 
remain there until some more decided symptoms presented 
themselves. 1 watched him carefully every day, and about the 
fifth day from the above date I perceived the lymphatic 
vessels on the inner side of the near hind leg to become 
swollen, after which the glands in their course rapidly en- 
larged, and pustules made their appearance about the eighth 
day from the date of admission. Many of these very soon 
burst, discharging a dirty yellow matter; those which did 
not were opened, their capsules being thin and almost ready 
to burst. Nitrate of silver was freely applied to all. Two 
days after its use, they assumed a healthier aspect, and pre- 
sented the appearance of small ulcers, varying in size from 
that of a sixpence to a shilling. They were washed twice or 
thrice during the day with a solution of sulphate of copper, 
and the same agent, in doses of a drachm, was given twice a 
day with the corn, of which the horse had from the first his 
full allowance. The appetite was good, and the animal in 
fair condition, considering he had lately returned from the 
Crimea. About the 5th of September the inguinal glands 
began to enlarge to about the size of a hen 5 s egg, resembling 
buboes. In a short time they burst, and discharged healthy- 
looking matter, it being white in colour and thick in consis- 
tence. Iodine was now given in conjunction with the sulphate 
of copper, in the form of the iodide of potassium, in drachm 
doses, twice a day. After this the buboes very soon healed 
up, and the leg rapidly decreased in size ; but there still 
remained something like twenty ulcers all the way up the leg, 
both inside and out. These w ere sprinkled with the sulphate 
of copper in powder daily, and they very soon began to heal, 
and in one week from the administration of the combined 
agents I had not more than half the number to deal with ; 
and these also showed a disposition to granulate and to heal; 
w hich they all did about the middle of the month of Sep- 
tember, excepting one just above the coronet, which remained
