The left is the flank usually chosen. A vertical incision in the upper part 

 of this region is made, sufficiently long to admit the hand, which is passed 

 in and upwards; the horn of the uterus will be felt just below the rectum, 

 as shown in the engraving, and, at the extremity of the horn, the egg- 

 shaped ovary. The ovary is drawn out of the opening and removed with 

 the escraseur, or by using a silk ligature and cutting it off with the scis- 

 sors. Thus the left ovary is extirpated. The right is next to be felt for at 

 the other horn of the uterus, and drawn out and removed in the same way. 

 Spaying through the vagina requires special instruments ; the principal 

 are a concealed knife, the torsion forceps or the ecraseur, or ligature. 

 It being too difficult an operation for anyone not an expert, our descrip- 



TIIE POSITION OF THE ORGANS OF THE MARK.

4 — Bladder. 



5 — Rectum. 



6 — Anus. 

 7, 8— Vulva.

tion of it will purposely be condensed. The i)lace wliere the opening is 

 made is the vagina, at a point just behind the neck of the womb, 

 at the top of the cavity. The opening needs to be about two and one-half 

 inches long, and parallel with the cavity. Through it the finger is passed, 

 and the ovary, when secured, is drawn into the opening and twisted oft" 

 with the forceps, or crushed off with the ecraseur, or cut off Avith the knife 

 and the vessels ligatured. This process is then repeated on the opposite 

 side. There are other instruments for dilating the vagina, and for guid- 

 ing to the place to cut, that we have not described ; they are very costly, and 

 of no use to the average horse owner.
