THE VETERINARY SCIENCE 
these glands not be destroyed by separation before the cuts 
heal there is a continual secretion of oil which in a short time 
gives the bag an enlarged, soft appearance not unlike that of 
a colt which had not been operated upon. Leaving the 
spermatic cord longer than it should be will produce the same* 
effect. 
Symptoms. — These are easily detected, especially in warm 
weather when the elastic fibres of the scrotum are relaxed. 
In cold weather the enlargement is not so easily detected, 
because of the elastic fibres of the scrotum being contracted. 
Purchasers of geldings during the winter months will require 
to look into this matter very carefully. 
Treatment. — It is necessary to impress upon the operator 
the importance of satisfying himself that there is no rupture 
before attempting to operate. Examine the scrotum and the 
inguinal rings above it to see that it is not a case of rupture. 
Prepare the colt by giving light diet for a day or two. Cast 
and secure as in ordinary cases of castration. Cleanse hands 
and instruments thoroughly. Wash the scrotum thoroughly 
with warm water and castile soap. Make a longitudinal 
incision in the scrotum parallel to the median raphe about 
three-quarters of an inch from it. A pouchful of fluid will 
be found inside the scrotum. Disect this out. This can 
generally be broken down with the fingers and should be 
done in this way when possible, as the less the knife is used 
the better. When this pouch has been loosened by disecting 
around it place the chain of the ecraseur over it, taking in all 
the spare cord possible, tighten the chain and cut it off in the 
same manner as in an ordinary case of castration. Oil the 
parts, before freeing the colt, with carbolized oil (five drops 
of carbolic acid to an ounce of sweet oil.) Operate on the 
other side similarly if necessary. For after treatment follow 
the same course as outlined for castration. 
VI. — Castrating Originals or Rigs. 
An original, ridgling rig is a male the testicles of 
which do not descend into the scrotum, but remain in the 
abdominal or belly cavity. The reason for this remains in 
doubt. It is advisable to leave cases of this kind to the 
expert, who pays especial attention to it, as the operation is 
extremely difficult to perform. If the testicles of a yearling 
hav^ not y [ descended into the scrotum it is advisable to
