MALARIA IN HORSES.

case, although at first no regularity of the exacerbations 
could be observed. The cough throughout was of a dry, 
choky character, with no expectoration, and gradually sub¬ 
sided. It was probably reflex from the liver disturbance. 
The membranes were never very much affected, but be¬ 
came slightly jaundiced toward the end of the courses. 
The following two cases, suspicious of malarial origin, were 
latelv observed. On the 26th of last December one of 
two well-bred, three-years old trotting colts belonging to Mr. 
Martin, of Ouincy, suddenly went “ off his feed,” and began 
acting very dumpish. The following day No. 2 became af¬ 
fected the same way, and the writer was then called in. 
Found both colts very dull and stupid, heads hanging, and 
ears lopped, and the eyes, or one eye at a time, half closed,— 
a position, by the way, that Dr. Griffin describes and assigns 
to headache, in which opinion the writer concurs. 
The temperature of No. 2 was 104.5° ; that of No. 1, 10?°, 
and the groom pronounced him brighter than on the previous 
day. Each colt received 3 ij of quinine, in pill form, and was 
given digitalis, quinine and cinchonida four times daily. In 
the evening the temperature of No. 2 was down to 102.4 0 , 
and that of No. 1 had not changed. The next morning, (28th), 
the temperature of No. 2 was 100.4°, and remained down all 
day, while that of No. 1 had risen nearly to 104°, and then 
receded to 103.2° by evening. On account of this rise in tem¬ 
perature, I gave each another 3 ij pill of quinine, this time in 
the evening. 
The next morning, (29th), the temperature of No. 1 was 
down to 100.6°, and stayed down, while that of No. 2 rose to 
101.2°, and then receded. 
That evening they received another quinine pill, and the 
cinchonidia and digitalis continued, four times daily. On the 
seventh day they were put on three grain doses of arsenic 
twice daily for four days in the week, and seemed to recover 
completely. 
In casting about for an explanation of these cases of inter¬ 
mittent fever, the fact presented itself that they were both 
deeply bedded from day to day with coarse prairie hay, cut
