HyEMATURIA (ACUTE REU-WATER) IN CATTLE. 131 
diminishes, as does also the appetite, and there are occasional shiv¬ 
ering fits, with alternations of cold and heat at the horns and the 
ears. The appetite by degrees entirely ceases—the secretion of 
milk is suppressed, or a very few drops only are yielded, and they 
are frequently of the colour of blood—the urine becomes of a 
more decidedly blood colour—it darkens beyond that, it is black 
—the pulse is small and frequent, as many as 80 in the minute 
—the beatings of the heart, however, the same in number, can 
frequently be heard at a considerable distance—the urine is voided 
frequently, and without pain—the loins will not bear pressure— 
the patient becomes exceedingly weak—the skin and the mucous 
membranes are deathy pale—the animal moans lowly and fre¬ 
quently—it at length lies down without the power of rising—the 
eyes are buried in their sockets, and the poor creature rapidly 
wastes away and dies. 
This disease runs its course with much rapidity, dating from 
the time that the urine begins to assume a bloody tint. In 
some cases the patients can scarcely be said to be ill; they seem 
to suffer no inconvenience; and if we did not see the colour of 
their urine, we should not suspect that any thing was the matter 
with them. With others, the disease takes from three to six 
days, rarely more, before it arrives at its greatest degree of in¬ 
tensity : in these cases it is always a serious affair, and utter loss 
of appetite - violent palpitations of the heart—general debility, 
and excessive paleness of the skin and mucous membranes, are 
observed. 
The malady continues from twm to four or six days : in a great 
majority of cases the animal is abundantly better or is dead before 
the expiration of this period. 
I have only seen one case in which haematuria was complicated 
with inflammation of the brain : here was stupor and som¬ 
nolence, rapidly succeeded by the utmost violence. The animal 
died about the tenth day. 
If we may judge of the intensity of the disease by the colour of 
the urine, we may say that, if we see it in one or two days change 
from a light red tint to the deepest hue, we may also see it, in fa¬ 
vourable cases, as rapidly recover its natural transparency. It 
is not so with regard to the general strength of the animal, which 
it takes a considerable length of time to recruit. If cattle are 
moved from a low to a mountainous country, and there contract 
the disease, every thing is changed w'ith regard to them—their 
food, their work, the soil, &c. They become presently fatigued, 
they stagger as they walk, and very soon are totally unal)le to 
w’oi k ; but, by degrees their strength returns, and they perfectly 
recover their former health.
