ON THE DEUTO-IODURET OF MERCURY. 
By the same. 
Case 1. — May 1841. — A bay pony, aged, the property of Mr. 
Alderman Birley, had induration of the off»knee, from a kick 
on the inside of the knee. He was lame, and could not bend the 
knee. 
After having it well fomented, I passed three setons around it, 
and had them dressed daily. In six weeks the swelling had de- 
creased a little, and the knee was much softer. I then began to 
apply the ointment in the proportion of two scruples to a drachm. 
It had an almost magical effect on the knee. In nine weeks it 
was reduced to its natural size, and the pony was quite sound. 
He is now at daily work, and continues quite sound. 
Case II . — June 1841. — A cart horse, the property of Mr. 
Trimmingham, of Marr Grange, had enlarged bursee that extended 
around the hock, and contained nearly or quite three pints of 
fluid : he was very lame, and had been repeatedly blistered, se- 
toned, and fired. After the application of the ointment for two 
months, the swelling was quite reduced, and the horse was sound. 
Case III . — June 1841. — A thorough-bred chestnut mare, in 
the Badsworth Hunt kennels, had induration of the fetlock. 
She had been stubbed in the near fore leg, and had been blis- 
tered and fired on account of it. The ointment was applied three 
months, and her leg became quite fine. 
Case IV . — August 1841. — A thorough-bred black colt, the 
■'‘property of Mr. Walker, of Clifton, had enlargement of the infe- 
rior maxillary bone. It was reduced after the application of the 
ointment for three weeks. 
In the following cases of splents, &c. there were both great 
lameness and enlargement : — 
A black horse, belonging to Mr. J. B. Linley, of Ham pole, had 
the ointment applied three weeks. He became quite reduced 
and sound. 
A bay mare, belonging to Mr. E. Shorts Martin. The oint- 
ment being applied for a month, the splent was reduced. 
A brown horse, belonging to Mr. Sheardown, had the ointment 
applied eighteen days. The tumour was reduced, and the horse 
returned sound. 
A bay gelding, my own property, that had been lame from 
curbs a considerable time: — I applied the ointment a fortnight; 
the curbs were reduced, and he became quite sound. 
A fine cow, the property of Mr. Long, of Brancroft. The
