ON THE EFFECTS OF IODINE.

especially seeing he only passed in 1840, and was a pupil here 
the three previous sessions, — that he has since been very generally 
present at meetings of the Medical Association of the students, and, 
I understand, a grinder to several of them, — that his brother was 
present in my class on several occasions when I spoke of the 
medicine, and the diseases in which it might be used. 
I am, dear Sir, 
Your’s truly, 
William Dick, 
To Professor DlCK,/rora Mr. T. B. Tennant. 
Worsley, 27th August, 1842. 
Dear Sir, — Since I received your’s of the 21st instant I have 
continued giving the horse — concerning which I wrote to you — 
one drachm of iodine twice a-day ; I mean to give one and a half 
to-night. He keeps improving, but very slowly. He feeds pretty 
fairly, but not with the appetite of a horse in health. 
His skin is quite loose upon his ribs, and in bringing my hand 
along it it feels quite soft, and the unctuous secretion is plentiful. 
He is also beginning to cast his coat. 
I must say, that he discharges an immense quantity of urine ; 
indeed, I am inclined to think that his lowness of condition is the 
effect of a morbid action of the kidneys. 
Altogether, he has a bucketful of crushed oats and beans, 
mingled with bran and linseed (all steamed together and made 
quite sloppy) twice a-day, with grass and sometimes hay, which- 
ever he inclines to eat : still his dung is no softer than a horse’s 
fed in the usual manner. His legs have no tendency whatever to 
swell. His thirst is still unabated. 
I mean to give him some pipe-clay in his water to-day. I 
would have given this before, but I imagined that the profuse stal- 
ing was the effect of the thirst. Will you be kind enough to give 
me your opinion with regard to this 1 
I am almost confident that I can put the horse in a condition to 
sell ; but that, you know, is not all that is required of a veterinary 
surgeon : he must restore his patient to his wonted health and 
usefulness before he can often gain the approbation of his em- 
ployer. 
I may also be permitted to state, that when he came to me his 
eyes discharged a considerable quantity of matter. That, however, 
is a good deal stopped.
