SULPHATE OF MAGNESIA A«N ANTIDOTE FOR CARBOLIC ACID. 
By J. Sterling, V.S., New York City. 
An imported two-and-a-half-year Leonberger dog was 
suffering with skin disease, and by advice of a dog-doctor was 
treated with carbolic soap and carbolized water. 
December 5 the dog received his first application, being 
well rubbed with the carbolic soap, which was allowed to re¬ 
main on him for an hour, when he was washed with a 3 per 
cent, solution of the carbolized water. In the afternoon of 
the same day he refused his food, was taken with violent 
vomiting, exhibiting symptoms of severe colic and diarrhoea. 
The temperature, when the dog was seen later in the day, 
was 96^; the pulse imperceptible; severe dyspnoea; the 
urine highly colored and brown; and the hinder extremities 
paralyzed. My diagnosis was carbolismus, produced by the 
absorption of carbolic acid in the system. 
The treatment consisted in the administration of three five 
gramme doses of sulphate of magnesia every half hour, with 
small doses of ether to keep him quiet. He passed a com¬ 
paratively quiet night, and recovered after four days of care¬ 
ful nursing and diet without further treatment. 
The chemical changes which must have resulted from the 
union of the sulphate of magnesia MgSo 4 and the carbolic acid 
CoH OH., can be represented by the following formula : 
CoH 5 OH-l-MgSo 4 =CoH 50 HS 03 -|-M:gCb> the carbolic acid 
and the sulphate being changed into sulpho-carbolic and 
oxide of magnesia. 
OVARIOTOMY IN THE MARE. 
By Wm. H. Ridge, V.M.D., and Simon J. J. Harger, V.M.D. 
The patient, a sorrel mare about nine years old, was owned 
by a Philadelphia gentleman from a colt to about six years of 
age, during which time she was gentle and quiet. On being 
harnessed she now began to show signs of kicking—switch¬ 
ing the tail, urinating when touched by the traces, and squeal¬ 
ing—but did not kick until when a seven-year-old. She was
