ANIMAL CASTRATION. 93 



adapt our treatment to the deep champignon of Zundel, 

 under one of its three forms of extra-inguinal, intra- 

 inguinal, and intra-abdominal. 



Under the first head we shall often discover, upon 

 inquiring into the history of the case, that for a 

 length of time, varying from months, perhaps, to 

 years, the animal had been affected with a swelling 

 which would gather, break, and slowly heal, leaving 

 no mark as an apparent indication of a diseased con- 

 dition, excepting that a certain degree of lameness 

 would have been observed to be present. Upon ex- 

 ploring the testicular region it would then be ob- 

 served to be the seat of a tumor, either spherical or 

 pysiform, seldom painful, and more or less adherent 

 to the envelope that covered it. Above this the end 

 may be felt free from diseased process, and this is 

 the champignon in its chronic form. In this condi- 

 tion it is not incompatible with the general health 

 of the animal affected, and forms no hindrance to his 

 usefulness. This condition of extra-inguinal growth 

 will sometimes dissolve away by an abscess-forma- 

 tion, and quite disappear. But if the induration of the 

 spermatic cord extends to the upper portion, or that 

 which is enclosed in the inguinal canal, in such a 

 manner as to interfere with locomotion, the leg cor- 

 responding with the diseased side being carried in 

 abduction, with numerous fistulous tracks existing 

 on the surface of the scrotum, the intensity of the 

 symptoms varying with the extent of the diseased 

 process, the condition of the cord will be easily dis- 

 covered by an examination of the parts, and the
