check movement of the hind legs. The hind legs are also partially 



secured by means of 

 ropes or two pieces 

 of webbing passed in 

 a running noose about 

 the hocks and fixed 

 above the knee. No 

 preliminary disinfec- 

 tion is practised, be- 

 cause no wound is 

 made. 



Manual Technique. 

 The operation com- 

 prises four stages : 



First stage. The 

 operator, standing be- 

 hind the animal's hocks, grasps the testicular cords with the hands, 

 immediately above the testicles, and by exercising strong pressure, 

 thrusts the latter to the extreme 

 base of the scrotum. The move- 

 ment is next reversed ; seizing the 

 base of the scrotum with the right 

 hand, he draws it smartly down- 

 wards, whilst he places the left 

 hand above the right, and thrusts 

 the testicles towards the abdomen. If 

 the testicles do not rise sufficiently 

 high, the right hand is slipped 

 between these and the left hand, 

 and the testicles are thus thrust up- 

 wards towards the lower inguinal 

 rings, slightly dilating the latter. 



After this manipulation has been 

 repeated two or three times, the 

 scrotum, etc., become more pliable 

 and the testicles more easily dis- 

 placed. The second stage of the 

 operation is thus facilitated. 



Second stage. The second stage 

 of operation may be effected by one 

 of two methods. 



Old method: The oldest method 

 consists in allowing one of the testicles to rise towards th
