tures from the suppurating wound where the second abscess 
was opened contained a white micrococcus and a streptococcus. 
Upon post-mortem examination there were found a series of 
multiple abscesses, ranging in size from a hickory nut to a 
man’s fist, located in the pelvic region, which had not been 
reached by previous operation. The tubes of bouillon and agar 
inoculated from one of the largest of these were pure cultures 
of a yellow micrococcus. The right kidney was the seat of a 
large abscess containing about a pint of pus. Pure cultures of 
a streptococcus were obtained from this pus. 
Case XIII .—Clinic No. 2264, Feb. 16, 1900. Patient, a 
bay roadster colt eighteen months old, was castrated last spring 
by the clamp method. The wound healed readily, but the owner 
noticed the scrotal sac to be filled, as he supposed, with in¬ 
testine. Upon examination the supposed intestine was found 
to be the tumefied cord with the end adherent to the skin. An 
incision was made at this point, the cord dissected from the 
surrounding tissues and removed with the emasculator. The 
wound was tamponaded with iodoform gauze and sutured. 
Following day the sutures were cut and the accumulated bloody 
serum removed. The cord was very much thickened and tum¬ 
efied and composed principally of white fibrous tissue. Tubes 
of bouillon and agar inoculated from inside the cord after re¬ 
moval remained sterile. From tubes of bouillon and agar in¬ 
oculated from the suppurating wound after the cords were re¬ 
moved, a streptococcus and white micrococcus were isolated. 
Case XIV —Clinic No. 2482, May 8, 1900. Patient, a 
bay cob, weight. 1000 lbs., eight years old; used only for carriage 
work. Was purchased in a pair six weeks ago as sound. Two 
days ago the owner noticed a swelling in the scrotum and some 
discharge therefrom. Horse has traveled peculiarly behind, pre¬ 
vious to this time. Upon examination a large tumor is felt in 
the right groin, none in the left. No tumefaction felt inside by 
rectal examination. There was a small fistula in the right side 
of the scrotum, which discharged at intervals. The tumor was 
removed in the usual way. The tumefied walls of the cord 
were composed of glistening white fibrous tissue. Walls vary 
from one-quarter to one-half inch in thickness. Cavity run¬ 
ning through the centre of the cord is about one-quarter of an 
inch in diameter. There were soft areas at certain points inside 
somewhat resembling actinomycosis. 
Tubes of bouillon and agar inoculated from the discharge 
before operating developed into pure cultures of a white micro-
