60 CASTRATION OF CRYPTORCHID HORSES. 



A post-viortem examination made by Mr T. D. Hughes, 

 M.R.C.V.S., and myself, revealed that the hemorrhage had 

 undoubtedly been the cause of death. There was no sign of 

 epididymis or testicle on the left side, the abnormality being 

 as here illustrated. There was just a small, thin, atrophied cord, 

 and from the fundus of the bladder the vas deferens could only 

 be traced for a few inches, when it imperceptibly disappeared 

 into the peritoneum. 



Professor M'Fadyean kindly examined the specimen. 



This animal had been bred by its present owner and no 

 attempt at castration had previously been made. 



No. 56. — This colt was seen to serve a mare on the 25th of 

 March but she has not proved in foal. The left testicle was in 

 the abdomen and the right one in the inguinal canal, neither 

 being visible from the exterior. 



Professor M'Fadyean examined both of them and reported : 

 " I find a very small number of spermatozoa in the right and 

 none in the left." 



No. 62. — The right testicle was discovered at the extreme top 

 of the inguinal canal and Prof M'Fadyean reported " I find that 

 a few spermatozoa are present." 



Nos. 66 and 70. — In each of these cases the testicle was found 

 in the lower part of the inguinal canal and contained a few 

 spermatozoa (Prof M'Fadyean). 



No. 68. — After a prolonged search the attempt to find the right 

 testicle was given up, it being thought that possibly the case 

 was similar to No. 50. For some months the horse was quiet, 

 but now the " rig " propensities have returned. As, however, the 

 horse is workable, the owner will not at present consent to a 

 further operation.
