however, was this accomplished than the brain was seriously in¬ 
volved. I combatted this new enemy, and the animal was gradually 
restored to a state of convalescence. Nevertheless the secondary 
cerebral affection has left as its sequela perfect gutta serena. I am 
conducting some experiments on the case, but I doubt whether they 
will prove of any avail. I have succeeded in two cases of paraly¬ 
sis ol the hind extremities by the use of the nux vomica, given 
internally. T am trying its effects on the gutta serena case, giving 
it also internally, and applying it to the surface of the skin during 
the action of blisters, as near the eyes as possible. The result I will 
communicate at some future time. 
A CASE OF BLACK-WATER. 
By Mr. W. A. CARTWRIGHT, V.S., Whitchurch. 
On the morning of the 14th of October 1839, Mr. Davies, of this 
town, requested me to see a five-year-old cow of his that was ill. 
He thought her not quite well the night before when milking her, 
but she then gave her usual quantity. 
Symptoms .—I had not been long there before I discovered that 
she had the black-water. She was hollow in the flanks, and often 
squirting a little thin dung of a yellowish colour, and straining 
much in passing it. I caught three or four quarts of her urine, 
which was the colour of port wine, and not tinged with blood. 
She was warm and comfortable, and her pulse at the heart full and 
strong, but her breathing was a little accelerated. I gave her mag. 
sulph. Ibss, sulph. sublim. Jiv, ol. croton gtt. xij, zingib. ^^ij in 
some gruel; and two or three hours afterwards I administered opii 
3 ss, and potas. tart. ant. 5 iss, to allay the irritation of the rectum. 
9 P.M.—The straining in a great measure subsided in the course 
of the day, and the dung that she purged since the morning would 
not fill more than a half peck measure. She has urined a great deal. 
I ordered that she should have no meat, and be left alone for the 
night. 
15/A. 7 A.M —The bowels have been moved only in very small 
quantities. She is getting weaker. The urine is about the same 
colour, and she voids it dribblingly. She grunts a good deal. I 
back-raked her, and drew a little dung from her. The first that 
came away was rather hard, but the other was softish, and it. was 
all very yellow. I gave her ol. ricini Ifeiss, zingib. 3 vj, and hyd. 
chlor. 3 j, in two doses, the one-half immediately, and the rest in the 
course of the morning. 
5 P.M.—I found her lying down and grunting a little, but the 
owner said that she had not grunted so much as yesterday. I 
caught four quarts of her water of the same colour, and she was
