ON SHEEP ROT. 
of them were very lame, so much so as to prevent their feeding, 
from ulceration round the coronet and between the tottles, and 
which b considered to be a disease analogous to the epizootic that 
has been so prevalent among cattle. I had all the detached horn 
cut away to prevent the dirt from lodging; and dressed the feet with 
an application composed of two parts of tar, one of spirit of turpen¬ 
tine, one of muriatic acid, and four of finely powdered sulphate of 
copper. The mode of preparing this is to put the tar into an earthen 
vessel, add the turpentine, slowly stirring the mixture all the time, 
then pouring in the acid, and, lastly, the sulphate of copper. This 
dressing must be repeated daily as long as the disease exists. 
I also administered Epsom salts Ji, and powdered aniseed 9i, 
mixed in a gill of water. This I considered a small dose, but the 
sheep were very weak. The treatment, however, had the desired 
effect, although it acted but on few as a purgative. The sheep 
after a week were all recovered, and throve very rapidly. 
Since that time I have had the lame of several flocks under my 
care, and have invariably met with the same success by using the 
sulphate of soda. 
I have no doubt this disease is communicated from one sheep 
to another, by a sound animal walking in the track of a diseased 
one ; or when foaled, from the lame ones being continually down, 
the discharge is left on the ground. My advice, therefore, is to 
draw all the lame sheep, and then commence the treatment pre¬ 
scribed ; preparing the medicine, and if not giving personal attend¬ 
ance, sending a given measure to be administered to each. Of 
course, large fresh sheep will require a corresponding dose. 
Permit me to add two not altogether unimportant cases on other 
diseases of this animal. 
Case I, was a fifteen months’ ram, of the pure Down breed, 
preparing for the late Agricultural Show at Cambridge. I met 
the shepherd on his road to ask my assistance. He informed me 
that he had a sheep with a stoppage in the water,—that the pre¬ 
sent case was the fifteenth animal that had laboured under appa¬ 
rently the same disease, and all of whom had either died or been 
destroyed. 
I found the animal down, and on his getting up observed a great 
anxiety of countenance, and a peculiarly sudden curvature of the 
spinal column; after which he passed a drop or two of urine. 
These symptoms had been observed continually for six hours, 
whenever he stood up ; his respiration was also hurried. 
On casting him and drawing out the penis, I found a small cal¬ 
culus forced a short distance into the appendix vermiformis, by 
the pressure of the urine from behind. I cut down on and removed 
the calculus, when the animal immediately voided it more freely
