against these causes that the therapeutic treatment must be 
directed.” 
Of fistula of the scrotum, Prof. Liautard says : “ Being al¬ 
ready aware of several causes of this complication of the opera¬ 
tion of castration, we may readily appreciate the treatment they 
require; it must be remembered that in a majority of cases the 
cause of this lesion is the presence of a foreign body in the 
wound, and that until it is removed it is in vain to look for a 
cure.” 
Prof. Smith, in his lectures on the diseases of the scrotum, 
says: 
“ These can generally be traced to some diseased condition of 
the spermatic cord, the result of castration, as scirrhus cord, ab¬ 
scesses, fistula, etc. Scirrhus cord may come in two or three 
weeks after castration, or it may come years after the operation. 
Abscesses may be caused by a foreign body, or may be due to the 
scrotum closing up before the cord is completely healed ; matter 
is formed at the cord, it becomes dry, sets up irritation and re¬ 
sults in an abscess; and when due to this it generally appears 
about three or four weeks after the operation, and it may be due 
to the incision not having been made large enough ; so I again 
recommend a pretty large incision. It may come from a small 
piece of iron remaining in the wound, if actual cautery has been 
used, or it may be due to a ligature setting up irritation, and the 
ligature should be left long, so it can be removed. 
“ Abscesses generally seriously interfere with the condition 
of the animal; should be opened freely, but may form again and 
again.” 
In the Deutsche Zeitschrift fur Thier-Medicm und Vergleich- 
ende Fcithologie , of May, 1886, Prof. Dr. Albert Jehne, of the 
Boyal Veterinary College in Dresden, Germany, claims to have 
discovered a micro-organism in several scirrhus cords that were 
removed from horses at the clinic of the above named college; 
and he also says that he found the same organism iu a tumor 
taken from the breast of a horse, said tumor having developed in 
an interval of about six months. 
And in the same article Prof. Jehne states that he submitted
