tide, cutting it some distance below the clamps, or as some 
operators do allow it to slough off. This I do not do, be¬ 
lieving it better to remove it at once, the clamp, however, must 
be allowed to remain until it sloughs off, when an adhesive in¬ 
flammation will have closed up the whole of the inguinal canal 
to the internal ring and the hernia with it. Care must now be 
taken with the diet, and the animal kept quiet for a few days. 
Another complication often met with, is the adhesion of the 
testes, this is readily overcome by dissecting out the cord and 
separating it above the point of adhesion ; then dissecting the 
testicle with the adhered parts attached, and removing the 
whole mass together. This operation is very similar to that 
performed in the removal of scirrhosis cords. 
Having thus hastily passed over the principal and most com¬ 
mon operations, I now come to one which a few years ago was but 
little practiced, but which is now of common occurrence, but very 
difficult to perform, and requires both judgment and skill. I 
refer to the castration of cryptorchids, commonly called ridg- 
lings through the inguinal regions. It has been done often 
through the flanks, as I have done it myself several times, but 
generally resulted fatally. By the term ridgling, I mean only 
that class of stallions in which the testicle is in an undeveloped 
condition within the abdominal cavity.

DIAGNOSIS. —It is not a difficult matter to make a diagnosis 
of typhoid fever in the horse notwithstanding the different forms 
it assumes. There is always the same general combination of 
characteristic phenomena. From the very onset of the disease 
the debility, stupefaction and oedema make typhoid fever of the
