A CASE OF RED-WATER. 
In the brook mentioned this grass is found in great abundance, 
and I cannot help fancying that eating it is one exciting cause of 
red-water. Another thing to be taken into consideration is, that 
the soil of this one brook is peaty, and consequently the water is 
impregnated with it, while that of the adjoining land is not so, 
neither does the grass beforementioned make its appearance 
there. It is very rare that a case of red-water happens to the 
animals pasturing in this land. 
I have had several cases, but the following was the most 
obstinate by far. Before giving a description of it, I may 
as well notice the general symptoms attending this disease. The 
first symptom noticed by the looker-out (who sees the animals 
twice a-day) is that the one affected has got away by him- 
self, and upon approaching him there is a peculiar expression 
of countenance not easily forgotten if once seen ; to which may 
be added, that the eye sinks into the orbit, and presents a par- 
ticular glassy appearance. The mouth and nose are hot and 
dry, staring coat, arched back from the irritation of the kidneys ; 
pulse generally accelerated, but weak ; general debility ; the 
animal, when very bad, staggering in his gait : sometimes a slight 
cough is an accompaniment ; the urine is of a dark colour, and 
frequently voided in small quantities. There is sometimes con- 
stipation, and occasionally diarrhoea. In slight cases the symptoms, 
of course, are not so bad as the above ; and 1 have generally found 
that, if taken in time, cases of this kind are soon cured by ad- 
ministering a brisk purge or two, followed by one or two of 
tonic medicine combined with diuretics. Constipation, after the 
urine has resumed its natural colour, is most fatal in this part, if 
the animal is not carefully watched. 
The case referred to is of a two-year-old steer, which I was 
requested to attend on the 18th of July, and had been ill with red- 
water three days. Three of my drinks had been given to him, and, 
although the urine was changing in appearance, still nothing had 
been voided per ano, 
I found the poor animal with all the worst symptoms, before 
explained, on him ; he appeared in great pain, and made a 
grunting noise with every expiration. I administered a powerful 
cathartic drink composed of sulph. mag., flor. sulpb., and sem. 
croton, and left another to be given in the evening, to which was 
added, spt. seth. nit. Jj ; I also threw up an enema, with orders to 
repeat it every four hours, giving plenty of thin oatmeal gruel, 
with pulv. zingib. in it. 
19i th . — No better. Repeat the cathartic drink, and continue the 
enema. 3 P.M. — Much the same ; no dung passed. It appearing 
to me that there was paralysis of the stomach. I stimulated the
