istic of stallions. The neck is large, but not as well de- 

 veloped as in the normal stallion, but the muscular system, 

 especially the buttocks, fall far below the average in con- 

 tour. 



The chief source of confusion in the diagnosis of crypt' 

 orchidism is the location of the affected side. In the supra- 

 scrotal ridgling the testicle is felt on palpation of the ingui- 

 nal canal, but in all the other varieties the diagnosis can 

 only be made in the recumbent position, by the examination 

 for the scar remaining from the castration of the normal 

 side, and by the palpation of the inguinal canal for the re-

mains of the spermatic cord of the previous operation. The 

 fact that two-thirds of all cryptorchid testicles are located 

 on the left side will materially assist in this connection. 

 If the region is not marked with fat the cord is easily felt, 

 and in most instances the scar is visible. The greatest con- 

 fusion arises when scars exist upon both sides, one from the 

 original castration and one from previous attempts to find 

 the hidden testicle. In this circumstance an attempt must 

 be made to locate the old spermatic cord on the castrated 

 side, and if results are negative the only recourse is to oper- 

 ate first on the left side, and then upon the right. Rectal 

 explorations are deceptive and very seldom fruitful.
