CASTRATION OF CRYPTORCHIDS. 
By Professor F. Mauri, of the Veterinary School of Toulouse, France. 
(Continued from page 131 .) 
Second .— DISPOSITION OF THE Testicles. 
Every author who has written on testicular ectopia in the 
horse has recognized two principal forms of cryptorchidy. 
In one, the abdominal , the testicle remains floating in the ab¬ 
dominal cavity, having failed to pass through the peritoneal 
orifice of the inguinal canal; in the other, the inguinal, the 
organ is more or less engaged in the inguinal tract. 
(a) Abdominal Cryptorchidy. —In this abnormality, which 
may be either simple or unilateral, or again double or bilat¬ 
eral, the testicle is attached to a peritoneal ligament more or 
less developed, which allows it to float in the neighborhood 
of the inguinal and prepubic, or again, more or less near the 
lumbar region. It is at the entrance of the pelvic cavity, 
along the ascending branch of the ilium in the direction of 
the flank, that it is most commonly found. 
In his first article on cryptorchidy, published in 1875, 
Prof. Degive has given in a concise manner the composition 
and disposition of the serous band which acts as a suspensory 
ligament of the testicle. He says : “ The suspensoiy appara¬ 
tus of the testicle is composed of two continuous folds ; the 
first, very long, wide, and extending from the sub-lumbar re¬ 
gion to the entrance of the pelvis, and containing between its 
folds the testicular vessels in front, and the efferent canal be¬ 
hind. The second, much shorter, narrower and falciform, 
connects the external face of the first with the lateral wall of 
the pelvic entrance ; its free border, somewhat thick, still 
carrying a remaining portion of th & gubernaculum testis . The 
suspensory ligament of the testicle has three free borders : 
one, the anterior, formed by the testicular blood vessels ; an¬ 
other, the posterior, by the efferent canal; and third, the ex¬ 
ternal, having for a base th e gubernacnlum testis . These three 
borders are united together by two serous folds, of which the
