ETIOLOGY OF SCIRRHOUS CORD, ETC. 
257 
Experiment No. 8.—May 28 th, 1886, castrated a grade 
Clydesdale colt, two years old ; produced two scirrlius cords, 
which I removed Sept, lltli, 1886; cords were about the diame¬ 
ter of a goose egg; scrotum was considerably swollen, but did 
not seem to inconvenience the animal in any respect. Could not 
remove the whole of the enlargements, as they extended up into 
the inguinal canal. 
Experiment No. 9.—May 28th, 1886, castrated a grade 
Clydesdale colt, one year old; produced scirrlius cord on right 
side, which was very globular in form; scrotum and sheath were 
swollen some. Removed the cord September 11th, 1886, with 
good results. 
Experiment No. 10.—June 4th, 1886, castrated a native bred 
one-year-old colt; produced the difficulty on the right side, which 
I removed on September 15th, 1886 ; the cord was as large as a 
man’s fist; the sheath was somewhat swollen, but did not seem 
to inconvenience the colt otherwise. 
Experiment No. 11.—June 4th, 1886, castrated a native-bred 
one-year-old colt; wounds healed up nicely. About four weeks 
after the operation the scrotum and sheath began to swell and 
reached an immense size ; colt could hardly walk. My attention 
was called to it on July 18th, 1886. I opened the scrotum with 
an abscess lancet, which allowed the discharge of considerable 
pus; swelling went down, and wound healed again. On August 
15th, 1886, I was called to attend the colt again. This time I re¬ 
moved an enlargement, about the size of a hen’s egg, from the 
end of the cord; colt improved nicely after the last operation. 
Experiment No. 12.—June 24th, 1886, castrated a native- 
bred one-year-old colt; wounds healed up nicely, and colt seemed 
to do well until the latter part of August, when he became un¬ 
thrifty, and tucked up in the flank; scrotum and sheath swollen 
so badly that he did not care to move; had to be fed in stable. 
On Sept. 2d, 1886. I proceeded to operate on him but could dis¬ 
cover nothing but a large abscess cavity, which I opened well, 
and the colt made a rapid recovery. 
I would state here that in making these experiments, which 
were of much detriment to my local reputation, I was not blind
