ON A PECULIAR DISCHARGE OF CALCULOUS MAT¬ 
TER WITH THE URINE, AND ON THE AFFECTIONS 
CONNECTED WITH SUPPRESSED STRANGLES. 
By Mr. MOGFORD, V.S., Guernsey. 
It is about seven years since I discovered that to be a fact which 
I had long before suspected; viz. that horses were not only subject 
to stone in the kidneys and bladder, but at times pass large quanti¬ 
ties of calculous matter; and, from the subjoined facts, with others 
which have come under my notice from time to time, I am led to 
believe (although I cannot absolutely prove it) that it occurs in 
horses who have attained their full growth without having had that 
complaint incidental to them called “ strangles.” I should have 
suggested this opinion long ago had I not been diffident of ventur¬ 
ing on an untrodden path, and more so, as I should probably broach 
an opinion contrary to that of many of my professional brethren 
whom I greatly respect, and to whom also I am much indebted. 
However, having read a case of the kind in your Number of the 
last September, fob 594, and seen your request to Correspondents 
to communicate similar cases, I have sent the following history. By 
the way, however, allow me to call your attention to Mr. Percivall’s 
invaluable work on “Hippo-pathology,” in which (p. 296) he de¬ 
scribes the symptoms of the horse with a staring coat, &c. &c. but 
does not specify the cause to which we are to attribute it. I shall be 
happy if the annexed statements may tend in any degree, however 
remote, to throw some light upon the subject. 
Case I. 
A horse, the property of Miss Sayer, of this island, was attacked 
with a peculiar stiffness in all his limbs—standing with his legs 
close together in a constrained position, as if they Avere fixed by 
some mechanical pov/er independent of the animal himself. There 
was no inclination to move. One leg was hot, and another cold— 
one ear hot, and the other cold; and the peculiar staring coat. I 
thought it might be rheumatism, and gave different remedies with 
little or no effect; but upon observing on the floor of his stall a 
sediment from his urine, in a considerable quantity, and of a sandy 
consistence, I altered Ins medicine, and gave the sulphate of iron 
and sulphuric acid, which effected a cure. 
Shortly after this treatment, inflammation of the parotid and sub- 
maxillary glands ensued, which ended in suppuration. The horse 
is now in good condition, and in the possession of Major Bain- 
bridge.
