DISCHARGE OF CALCULOUS MATTER. 
dition—that he was frequently ailing, and yet the ailment assumed 
no tangible form. He had also the peculiar staring coat. 
About a month after his recovery from this attack of inflamed 
bowels I was again called upon to attend him, he having fallen down 
in his harness while standing at a door. He has had seven or eight 
of these attacks, and the appearances at those times are redness 
of the conjunctival membrane, the Schneiderian membrane being 
of a purple hue—dilated pupils—a wild look—hard and quick 
pulse, and every symptom of approaching death. I bled him freely 
the first time, and opened the bowels; but still the giddiness re¬ 
mained. 
Some time afterwards 1 perceived that a most intolerable stench 
arose from his urine. Having ascertained that the urine contained 
excess of lithic acid, and stating the case to Dr. Magrath, of this 
island, he kindly suggested my trying the effect of the liquor potassse 
in a mash thrice a-day, increasing the dose to two ounces. In a 
short time it produced a wonderful alteration. It entirely removed 
the stench from the urine, opened the pores of the skin, and worked 
an entire change in the appearance of the horse. I observed parti¬ 
cularly a constant dewy wetness on his cloth from the condensed 
cutaneous perspiration immediately over the region of the kidneys. 
The last eight months he has done a great deal of work, but has had 
no return of giddiness. 
Case V. 
A horse of my own, nearly thorough-bred, which 1 reared from 
a colt, and which had been always particularly healthy, with a fine 
satin-like coat, has, for the last three months, exhibited great dul- 
ness after the administration of medicine, and also a staring un¬ 
healthy coat. One day on putting him into the stable for a short 
time, he staled, and I afterwards observed on the floor about a table¬ 
spoonful of deposit in appearance like wet brick-dust. Having 
collected as much as I could, I gave it to a chemist to analyze, who 
found it to consist of carbonate of lime. This horse was five years 
old last April, and had not had the strangles. I gave him, as in 
the other case, the sulphate of iron and sulphuric acid; after which 
a swelling took place in the hind legs. He very soon regained his 
healthy shining coat. 
In all the afore-mentioned cases the legs were particularly fine 
before the medicine was given; but afterwards the glands of the 
throat swelled and suppurated, or the legs swelled. I do not mean 
to say, that all the above cases were those of suppressed strangles; 
but I am led to suppose that the affection described was connected 
with a derangement of the glandular system of the body.
