Case II. 
A blood-foal, about a fortnight old, was affected with diarrluEa. 
In order to relieve him, the yolks of eggs, port-wine, &c. had been 
administered—favourite medicines in our island. On the next day 
he died. 
On examining and cutting into the pelvis of the left kidney, there 
was a most extraordinary large portion of it incrusted round with a 
kind of shell-like substance, and the space filling up from the bot¬ 
tom with a calculus. This incrustation must have occupied a con¬ 
siderable time in forming, and its origin must have been coeval with 
or prior to the birth of the animal. Had the colt lived the stone 
would have been of immense size. I had promised to have sent 
it to a medical gentleman, but, by some unfortunate means it was 
lost. 
Case III. 
A five-year-old horse, the property of William Brock, Esq., had 
the fetlock-joint punctured by a nail. After the joint was closed, 
ossific matter was thrown out, to remove which the actual cautery 
was applied. This horse was similarly affected with that of Miss 
Sayers, described in Case I, only the symptoms were of a more ag¬ 
gravated character. The calculous deposit left from the urine would 
frequently fill up the small drain under the grating of his stall. I 
tried several remedies, but succeeded in curing him with the sulphate 
of iron and sulphuric acid, in very large doses: I sometimes gave 
it to him in bran and ground oats, and at others in water alone. 
He w'as soon relieved, and in six weeks got into good condition. 
In this case strangles did not follow, but swelling of all four legs 
ensued, with cracks and discharge of matter from the heels. He 
has been nearly three \ ears in constant work since, and has suf¬ 
fered no relapse. Dr. Scott, of the Rifle Brigade, analyzed the 
deposit from the urine, and found it to be composed of the sulphate 
and carbonate of lime. 
Case IV. 
A valuable old hunter, the property of Captain Greathead, of the 
8th regiment, soon after landing in this island was attacked with 
inflammation and stoppage of the bowels, occasioned, I believe, by 
a torpid state of the liver — the faeces being of a yellow clayey 
colour. We took from him a very large quantity of blood, and 
after the inflammation had subsided I gave him the blue pill. The 
groom’s account of him was, that it was difficult to keep him in con-
