coccus. Those inoculated from inside the cord remained sterile. 
However, iodine had been injected before operation, which might 
account for this. Media inoculated from the wound three days 
after operation developed into cultures from which a streptococ¬ 
cus and white micrococcus were isolated. 
Case XV .—Clinic No. 2491, May 10, 1900. Patient was 
a black gelding, weight 1050 lbs., 7 years old, and used for farm 
work. Was castrated when two years old, and nothing was 
noticed amiss until last fall, when a slight discharge was 
noticed after the horse had been lying down. Upon examina¬ 
tion a hard tumor was found extending up in the groin to the 
external inguinal ring on the left side. Rectal examination re- 
vealed nothing except a slight dragging upon the spermatic 
artery and cord. The tumor was all extra-abdominal and about 
three by one and one-half inches in size. Upon cutting open 
after removal the walls were found thickened and composed of a 
thick white fibrous tissue with soft areas at points on the inside. 
Pure cultures of a yellow micrococcus were obtained from the 
pus contained in the abscess. 
Case XVI .—Clinic No. 2529, May 18, 1900. Patient, a 
brown two-year-old colt; was castrated about a year ago. When 
seen in the clinic there was a soft tumor in the scrotum which 
evidently contained fluid. The cord was removed and found to 
be dropsical. The walls were not markedly thickened, but were 
distended to about the size of a large hen’s egg with a serous 
fluid from which tubes of bouillon and agar were inoculated. 
These cultures remained sterile. 
Here, in connection with scirrhous cords and deep shoulder 
abscesses, may be a proper place to discuss a disease which we 
know very little of and concerning which there seems to exist 
a diversity of opinion, viz. : botryoinycosis. It is defined by 
Gould as “a disease of horses in which fibromatous nodules 
form in the lungs. It is dependent upon the presence of a 
micro-organism called botryomyces.” . 
Jensen* considers it as closely allied to actinomycosis, and 
says regarding it: “ Actinomycosis is found in man, cattle 
and swine and only in the horse by inoculation, while botryo- 
mycosis is peculiar to the horse, and after surveying the litera¬ 
ture we find it only once observed in cattle. But like actino-
