106 ANTISEPTIC TREATMENT OF WOUNDS. 
(c) Carbolic Acid, 95 per cent. 
‘¢d) Iodoform powder. 
(e) An emulsion consisting of Thioform 30 grams, Sodium 
bicarbonate 30 grams, and Glycerine 240 grams. 
(f) An ointment consisting of Thioform or Iodoform 15 
grams, and Lanolin 240 grams. 
(g) A large clean tray for the instruments. 
(h) Clean metal pails for the antiseptic solutions. 
(i) Casting harness and twitch. 
The Operation :— 
ist Step:—The animal is placed in the dorsal position, the 
legs well parted and the scrotum, sheath, penis and posterior 
abdominal region energetically scrubbed with soap and hot 
water and then sponged for a time with a solution of mercuric 
chlorid, 1-200. 
and Step :—The scrotum is dried moderately with the steril- 
ized sponge and then sprinkled with iodoform powder, which 
is rubbed in well until a dry crust results. 
3rd Step:—The testicle is then exposed by an incision as 
small as possible, and now instead of grasping it with the hand 
it is pulled from the scrotum with the forceps. The ecraseur 
chain, without permitting it to touch the hands, is passed over 
the forceps and testicle and adjusted to the proper place upon 
the spermatic cord. When the cord is sufficiently crushed, 
twist the testicle off with the forcep before loosening the ecra- 
seur. Hold the cord in the center of the wound with the 
ecraseur and pour 120 grams of the emulsion into the scrotum 
and disseminate it by circular motions of the ecraseur, which 
is still holding the cord. 
Ath Step :—The ecraseur is now loosened and placed in a tray 
containing a 10 per cent. solution of carbolic acid, where the 
scalpel, sponge and forcep have been previously laid. As the in- 
struments were aseptic, it was not necessary to place them in 
such solution for the first testicle, but as they have now been in 
contact with the hands of both the assistant and surgeon, their 
disinfection is very essential to insure success. 
5th Step :—Remove the opposite testicle in the same manner
