HYDATIDS IN THE BRAIN— II El FEU.

She returned from grass on the 28th of June, the glands being 
nearly as large as before, and the discharge continuing from the 
right nostril. In this state she continued until the 6th of July, 
when, in the course of twenty-four hours, she had two sponta- 
neous plentiful bleedings from that nostril. 
From that time the discharge began to diminish, and at length 
entirely ceased, and for many a year she has continued perfectly 
well. 
Hydatids in the Brain — Heifer. 
By M. Duflenne. 
Case I. — On September 13th, 1829, I was requested to ex- 
amine a heifer, two years old, in good condition, but who, during 
the last two or three days, had been dull, and careless about her 
food. The conjunctiva was injected, the pulse accelerated and 
hard, and the gait staggering ; but there was no tendency to in- 
cline either to the right hand or to the left. After attentively 
examining her, I thought that I recognized an affection of the 
brain or its membranes ; I, therefore, abstracted eight pounds of 
blood from her, and ordered her to be put on a restricted diet. 
1 6th. — She was a little better ; but she separated herself from 
her companions, and crept close to the hedge. 
24th. — She continued separated in the same manner. The 
right eye was clouded, and as she walked she now had an evident 
tendency to go round in a circle. I tried this several times, and 
always with the same result; and she always turned the same 
way. I now recognized the disease commonly called turnsick 
( tournis ), produced by an hydatid in the cranial cavity. 
I explored, by means of percussion, the whole of the cranial 
roof, but unsatisfactorily ; for I could nowhere distinguish any dif- 
ference in the sensibility, the flexibility, or the sound yielded by 
striking the different parts of it. I communicated my opinion 
to the owner. I spoke of the hazard of an operation, and rather 
advised him to send her to the butcher. He wished me to have 
recourse to the trephine. I somewhat reluctantly consented, 
but begged for the delay of a month, hoping that in that time 
the portion of the skull over the hydatid would become softened , 
and that I should be able to operate with greater certainty and 
safety. 
The symptoms became every day more alarming, especially that 
which characterized the disease, namely, the disposition to go 
round, and on one side; indeed, that symptom was displayed in 
the most decisive manner : she would be continually describing
