180 H/EMATUllIA (ACUTE IlED-WATER) IN CATTLE. 
But, though I utterly deny this doctrine of “ expansion”— 
though I maintain that the foot is naturally always of the same 
size, on or off the ground, in action or at rest—let me not be sup¬ 
posed to consider it as a block of granite. I yield to no man in 
admiration of its wonderful structure and economy. 
I am next asked, '‘What office I assign to the frog?” The 
horse’s hoof, so far from being “cleft” or “divided,” is a horny 
box, or covering, to the sensible parts of which the foot is at¬ 
tached: of these the frog, formed of highly-elastic materials, is 
a most important part when its functions, on meeting the ground, 
are not interfered with. One of these is to break the concussion 
the foot would otherwise sustain, and also, by its upward and 
lateral action against the side cartilages, where the expansion 
really takes place, to keep the horn as it is secreted, in the form 
which was intended by nature. Such is the office of the frog. 
His gratuitous assertions I hope I have answered to the 
satisfaction of all impartial judges; and I beg to assure him, 
in conclusion, that all he may hereafter choose to assert shall be 
met on my part with that silence which his vanity may interpret 
in one way, and impartial judges, perhaps, in another. 
H-^MATURIA (ACUTE RED-WATER) IN CATTLE. 
By M. DrouArd, Monbard, 
The frequency of this malady in the last spring having en¬ 
abled me to observe several phenomena respecting it, which no 
practitioner has yet described, I am tempted to present to you, 
not a perfect monographie of this disease but, an account of 
certain symptoms and lesions, and which go far to indicate the 
causes of it, at least in our country. 
It is rare that we are called in at the commencement of this 
disease ; but when we do first see our patient, the following lesions 
usually present themselves. The pulse is slightly irregular—the 
urine high-coloured or assuming a reddish tint—the animal 
preserving for a short time its spirits and appetite — the muzzle is 
abundantly moistened with its natural dew : but presently the 
breathing becomes accelerated—the pulse is small and wiry—the 
urine takes on a bloody colour—the coat stares—the muzzle 
becomes dry—the secretion of milk, if the patient is a cow, 
en voyage quand un cheval a perdu son fer.”—The plates representing this, 
and other shoes, are in a very good state of preservation. A good copy may 
be seen in the library of the British Museum. The Supplement, published in 
1758, to the Duke of Newcastle’s splendid work on hosemanship, also no¬ 
tices this make-shift shoe, or shoe for all feet.
