EXTIRPATION OF THE EYE. 



The old way of castrating with chun[)s is convenient, but it gives rise 

 to an immense amount of pain, and is a quite inferior method compared 

 with using the ccraseur. 



Vn. Extirpation of the Eye. 



In cancerous growths in the eye, it is sometimes necessary to extirpate 

 that organ. After casting the horse, pass 

 silk threads thrcjugh the lids, so that an 

 assistant can hold them open ; then, with 

 a sharp knife, dissect the eyeball out, 

 cutting the muscles as they come, one 

 after another, and, finally, the optic nerve. 

 Dress the socket with lotion No. 39, for 

 a fcAv da3'S ; then change to lotion No. 7. 

 As this is a very painful operation, an 

 anaesthetic should always be used, if a 

 skillful man can be got to manage the 

 case. 



VIII. Firing. 



This is the ai)plication of the actual 

 cautery (burning by red-hot iron) to 

 set up a great amount of counter-irritation or of adhesive inflammation. 

 Its most common applications are for ring-bones, curbs, and sprains of 

 the back, tendons, etc. Clip off the hair, cast the horse, and draw the 

 edges (which should be blunt) of the firing-iron on the skin, making a 

 yellow crease on it, but avoid cutting through the skin, as that would 

 blemish more. Draw the lines, in the form of a feather, over a con- 

 siderable surface ; let the horse up, and rub in the blister immediately. 

 Give absolute rest for a month, and a run at grass for two months. 



IX. Lithotomy. 



This is an operation to extract a stone from the bladder. Cast the 

 horse, and insert a metallic sound into the penis to reach up to the curve ; 

 cut down to it on the curve, then insert a hidden bistoury, and open the 

 passage into the bladder, making it large enough to allow of the stone 

 being got out. Insert forceps with one hand, tiie other hand being in the 

 rectum and following up the stone and crowding it out. If too large to 

 extract whole, try and break it up with the forceps. 



If the patient is a mare, it will not be necessary tv'> cast the animal. 

 She can be controlled suflaciently by using a twitch, which is a loop of 

 strong, small rope, on the end of a small stick, for twisting the uppei
