and index finger. Holding the ovary with one hand tighten 

 the chain quickly with the other, examine to make sure 

 that a loop of intestine is not caught, draw the ovary well 

 through and get a large portion of the oviduct, and crush 

 off promptly, holding to the gland until carried out through 

 the vulva. Remove the other ovary in the same way. 

 Generally it is most convenient to remove the left ovary 

 with the right hand and vice-versa but each may be re- 

 moved with either hand. Wash away any blood from the 

 external parts, apply sublimate solution freely to the vulva, 

 perineum and tail. Keep the patient quiet for five or six 

 days, and feed lightly on a laxative diet. 



II. In operating under anae.sthesia the animal should be 

 cast or confined upon the operating table in lateral re- 

 cumbency preferably with the posterior part of the body 

 somewhat higher than the anterior so as to avoid visceral 

 pressure in the pelvic cavity. Place the animal under com- 

 plete anaesthesia. Prepare the parts in the same manner 

 as already described. Carry the knife into the vagina in the 

 manner previously described and render the roof of that 

 organ tense by pushing the os uteri downward and forward 

 with the hand or by means of a vaginal tensor or speculum. 

 It is important that the vagina be held well down toward 

 the floor of the pelvis so as to carry it away from the rectum, 

 posterior aorta and iliac arteries while the incision is being 

 made. The incision is now to be made just above and be- 

 hind and a trifle to one side of the os uteri in essentially the 

 same manner as under I, except that when the vaginal 

 tensor is used the cut is made upward and backward instead 

 of directly forward. The remainder of the operation is 

 identical with what we have described under I. Under 

 anaesthesia the vagina is flaccid and can not be made to 

 " balloon."
