HYDATIDS IN THE BRAIN— HEIFER. 117 
from her trammels; she got up with difficulty, and she was put 
on a very restricted diet. 
I saw her about four hours after the operation : the eye was 
wandering, the pulse small and accelerated, but she no longer 
turned . 
On the following day the eye wandered ; the pulse was still 
more quickened and hard ; at times she was beside herself, and 
every symptom indicated an attack of inflammation of the mem- 
branes of the brain. 
I abstracted eight pounds of blood from the subcutaneous 
abdominal vein, with a view to cause a new direction in the 
current of blood. I ordered the application of cold water to the 
head, draughts of a decoction of linseed, and drinks of acidulated 
white water. 
Nov, Is/. — The symptoms of meningeal affection have much 
diminished, yet the patient is to a considerable degree comatose. 
Apply a blister to the inside of each thigh. In the evening she 
seemed to search for food, and a little hay was offered to her, 
which she ate. 
2d . — The blisters have not acted well, but she is much better. 
The pulse is neither quickened nor hard, and in fact, from this 
day, the rapid progress to convalescence may be dated. Eight 
days after the operation, the forehead was examined. The wound 
was perfectly healed. The depression occasioned by the remo- 
val of a portion of the frontal bone became so completely closed, 
that, three months afterwards, the place where the operation had 
been performed could scarcely be pointed out. 
CASE II. 
Feb . 15, 1830. — I saw a bull with the same symptoms as this 
heifer, except that the progress of the disease was slower, and 
the animal was less violent. It was not until three months after 
the first appearance of the disease that I could be induced to 
operate ; but the operation succeeded. The hydatid was larger 
than in the preceding case, but it was extracted whole. There 
were no subsequent symptoms of arachnitis, consequently he was 
not bled : there was some marked debility for awhile after the 
operation, but eventually the animal perfectly recovered. 
These cases are the only ones that have occurred in my prac- 
tice. I was induced to operate only at the earnest request of the 
owners ; but hereafter I should have less hesitation, provided I 
could be assured that the hydatid had sufficiently developed 
itself. In each of these cases the hydatid was placed on the 
right lobe of the brain beneath the membranes and near the 
falciform septum between the lobes of the brain. The parasite
