FISTULOUS WITHERS. 
13th. —To-day I was prevented by other engagements from 
visiting my patient at Weston. 
llth. —Upon the whole, the aspect of the sore is favourable, 
but at the posterior part there is a depression and loss of sub¬ 
stance, wherein a small quantity of matter is lodged. Con¬ 
ceiving that a sinus was likely to be formed here, I introduced a 
seton needle, and brought it out about three inches beyond the 
boundary of the abscess. The matter passed through the opening 
thus made, and the sore was dressed as before. 
1 3tli. —The horse was this day brought to my infirmary, in 
Southampton, and a daily dressing with sol. zinci sulph. was 
resorted to for about a week, the incisions and seton being kept 
open. The wound filled up very slowly, and although progress 
was made, it was not so rapid as I wished and expected: neither 
did the granulations assume a healthy appearance; and instead 
of laudable pus, there was a considerable discharge of a thin 
ichorous character. In consequence of this, I altered my plan, 
and used a solution of the chloride of lime After a very few 
dressings with the chloride, its excellent effects were visible ; the 
ichorous discharge ceased, and the granulating surface became of 
a beautiful healthy colour: the wound filled up and cicatrized 
without the slightest untoward appearance, and on the 14th ol 
August the horse was discharged; since which time he has been 
at regular work. 
I have quoted the preceding case solely for the purpose of 
adding my humble testimony to the value of chloride of lime as 
a stimulant : I believe it is a medicine which is daily gaining 
ground in our profession, and by and by I trust to see it in 
general use: like many, nay almost all other medicinal bodies, 
its virtues and effects upon our patients are but very imperfectly 
known. Surely at no distant day we may hope for an inquiry 
into this very fertile subject.
