449 IODINE IN GLANDERS. 
systematic plan, nor followed up with a degree of* zeal worthy of 
such a cause. 
My talented and excellent friend, Mr. Percivall, was early in 
the field. He had a horse in his infirmary (in the spring of 
1833) evidently farcied. A chorded chain of connexion could 
be felt between certain pustules that had appeared upon him. 
Nearly six weeks from the first appearance of the farcy, traces of 
glanders, which could not be mistaken, appeared in the right 
nostril, and he was put under the influence of iodine. Three 
grains of the mineral were given morning and evening. Two 
days afterwards the dose was increased to five grains twice in 
the day ; and at the expiration of a fortnight each dose had been 
increased to half a scruple. This plan of treatment was pursued 
two months ; but the disease progressed from bad to worse, 
until all hopes of benefit derived from the iodine having totally 
vanished, the patient was destroyed. 
A little earlier in the same spring he had a horse with pure 
farcy. The patient had calomel and aloes, and diuretic medicine 
daily ; mercurial friction was employed, and, still later, the power 
of the sulphate of copper was tried ; but the horse got worse 
and worse. Two months nearly had now passed, when Mr. 
Percivall determined to try the effect of the iodine. He began 
with five grains daily, the disease appeared to be rapidly gaining 
ground, and a week after the commencement of the iodine, the 
dose was increased to ten grains daily. Still the malady was 
evidently progressing ; the dose was then rapidly increased to a 
scruple. The horse began evidently to amend, and in three 
weeks from the commencement of the full dose, and six from 
the first exhibition of the iodine, and thirteen from the appear- 
ance of the disease, the farcied swelling had subsided, the sores 
had quite healed, and the horse was sent to work. Mr. Percivall 
very candidly adds, that “ the green diet” (for he was turned 
into a small field when he began to take the iodine) “might 
have much contributed to the cure.” It might so, but the chief 
praise is evidently due to the iodine. 
There is nothing contradictory in these two cases. Farcy, 
which is occasionally under the control of several of our medi-
