INTERMITTENT FEVER IN THE HORSE 
At three o’clock, however, the symptoms of fever declared them¬ 
selves : they were exactly the same as those observed in the pre¬ 
ceding case, except that the eyes were not closed, and the verte¬ 
bral column was flexible: he walked easily, and the arteries 
were full. 
On the second day, the fit was as violent as usual. I then, at 
midnight, gave him ten grains of the sulphate of quinine in eight 
ounces of water: at four in the morning, ten grains more ; four 
hour after, another ten grains ; and the same quantity at noon. 
At three o’clock in the afternoon the animal continued to preserve 
his natural gaiety and appetite; in a word, the symptoms of 
fever were not perceived: nevertheless, I gave the patient four 
more doses of the quinine, of the same quantity and at the same 
hours as yesterday. No symptoms returned. I continued, for 
nine days, to administer this medicine, and in the same manner 
as I had done to the horse mentioned in the preceding case. 
The animal was discharged from the infirmary on the thirteenth 
day, and resumed his ordinary work, which he has since con¬ 
tinued to do without experiencing the slightest illness. 
Case III.—The 20th October, 1828, a draught horse, of good 
constitution, and of the Percheronne breed, belonging to my fa- 
therdn-law, M. Breton, proprietor and farmer at Allaines, was 
brought to me. For some days before the horse was brought to 
me, at about seven o’clock in the evening, the animal became 
suddenly dull, ceased to eat, supported his head on the edge of 
the manger, and drew up his four extremities under the centre of 
gravity, and from this position it was almost impossible to move 
him. Shiverings of the whole body were soon perceived ; and it 
was not till nearly an hour and a half afterwards that all these 
symptoms ceased, excepting a little feverish heat. 
After what was told me, I pronounced that the horse had in¬ 
termittent fever of a quotidian type ; and I was not deceived, for 
at seven o’clock in the evening I witnessed every symptom of this 
kind of fever. 
The next day, at four in the morning, I gave the animal twelve 
grains of sulphate of quinine in nine ounces of water; four hours 
after, twelve more grains; at noon, twelve; and at four in the 
afternoon, twelve more. 
Three hours after the last dose, I saw nothing of the symptoms 
which I had observed on the preceding day. 
This horse was submitted to the same treatment as the former 
two for nine days : the dose of sulphate of quinine was diminished 
in the same manner (eight, six, and two grains), and on the four¬ 
teenth day the animal was returned to M. Breton. 
Case IV.— November 10, 1828. A cart horse of the Per-
