ESSAY ON INFLAMMATION OF THE BRAIN.

the opportunity of seeing his patient. He induced the owner of 
the calf to bleed it copiously, and to adopt the means that have 
been described under the former cases. 
An empiric was employed to carry all this into execution; but 
he abstracted only two pounds of blood, instead of the twelve 
which M. Mullon had ordered, and inserted his seton on the fore- 
arm, instead of the situation that had been directed. 
The disease rapidly pursued its course, and the animal, at li- 
berty in one of the courts, wandered here and there, distinguish- 
ing no object, although its eyes were perfectly clear, and every 
stone or other irregularity of surface causing her to trip and fall. 
When she had fallen she remained on the ground until some one 
came to raise her. If she was stopped in her progress by the 
trunk of a tree, or any elevated object, she would push her head 
against it, and remain immoveable until she was taken away. If 
she was stopped by a wall, or faggot-rick, she would support her 
head against it, but without violently pushing, as the vertiginous 
would do. She seemed to be merely supporting her head against 
the wall, instead of pushing violently against it, until she was led 
away. There was no inflammation in the eyes or the nose, the 
larynx or the pharynx, as in the cases already described. The 
pulse was full without being accelerated ; the bowels were open, 
and the urinary secretion as it ought to be. 
M. Mullon saw the patient on the 2d of September, at night, 
and he immediately bled her to the extent of thirteen pounds, — 
cut off one of her horns, and left the hemorrhage to itself — applied 
a poultice of hot mallow leaves to the head, and frequently admi- 
nistered some linseed tea, acidulated, and thickened with oat or 
barley meal. He frequently gave these drinks, both acidulated 
and farinaceous. He did not place a seton in the dewlap, because 
that which had been introduced inlo the dewlap formed a frightful 
wound. Without the knowledge of the veterinary surgeon, this 
seton had been dressed with camphorated brandy, which had alto- 
gether arrested its suppuration. In despite of this, after four or 
five days’ treatment, the intensity of the disease very much dimi- 
nished, and, at the expiration of ten days, she was in a state, of 
convalescence. She, however, carried her head low, and there was 
a sluggishness about her which indicated some cerebral disease. 
M. Mullon substituted the application of cold to the head for the 
poultice of mallows, and this completed the cure. 
M. Mullon has endeavoured to prove, by a course of reasoning 
too long to transcribe here, that the disease of this calf was slight 
inflammation, altogether similar to those which had been already 
described, and not vertigo. 
As confirming these interesting cases sent to me by M. Mullon,
