we believe their etiology and morbid anatomy to be very simi¬ 
lar in character, the chief difference in them being in the seat 
of the lesion. Hence we have considered the two under one 
heading. We have had occasion to study but two of these cases 
during the past year, the notes on which are given. 
Case l III. Clinic No. 195^ Oct. 10, 1899* Patient was 
a brown horse, weight 1100 lbs., 8 years old, and used for 
general farm work. Was castrated when two years old and 
since that time there has been a tumor in the scrotal region, 
but as this had never caused any inconvenience to the animal 
little attention was paid to it. 
About August 1st there was noticed on the poll a swelling 
about half the size of a goose egg 5 this has gradually enlarged 
until at the present tune the whole region of the poll is 
greatly swollen and discharging from two openings. Each 
side can be probed for a distance of two and one-half to 
three inches. From the tubes of bouillon and agar inoculated 
fiom the discharging pus were isolated a streptococcus and a 
white micrococcus. 
Case IX .—Clinic No. 2443, April 27, 1900. The patient, 
a sorrel horse, weight 950 lbs., 14 years old, was trading stock 
and hence nothing was known of the history of the case. When 
presented at the clinic there was a small opening at a point on 
the second cervical vertebrae. This opening was enlarged to 
admit the finger and the fistulous tract found to extend about 
three inches posteriorly and also a short distance anteriorly. 
This was laid open for its whole extent. Tubes of bouillon 
and agar weie inoculated from the discharge and a streptococcus 
and a white micrococcus were isolated therefrom. 
BOTRYOMYCOSIS (SCIRRHOUS CORD AND SHOULDER ABSCESSES). 
In the title we have classed scirrhous cord and deep shoulder 
abscesses together as botryomycosis. They seem to be the two 
commonest forms of this disease as it is described by those 
who have worked upon it. 
Scirrhous cord is a disease which seems to be decreasing in 
prevalence as the more modern and scientific methods of aseptic 
and antiseptic castration are adopted. The duration of the 
disease often dates back to the time of operating 5 the wound 
never having healed completely, but a fistula remaining. On
