It is also necessary, before the final fixing of the clams, to determine on the part where the division of the cord is to take place. To use Mr. Percivall’s words, “If it be left too long, it is apt to hang out of the wound afterwards, and retard the process of union;” indeed, I have known the end of it swell into a fungous excrescence, which greatly embarrassed the practitioner to destroy: on the other hand, if it be cut very short, and the arteries happen to bleed afresh after it has been relieved from the clams, the operator will find it no easy task to recover it from the retraction of the cremaster. The natural length of the cord, which will mainly depend on the degree of the descent of the gland, will be our best guide in this particular. The place of section determined on and marked, close the clams sufficiently tight to retain firm hold of the cord, and to effectually stop the circulation within it. There are now two modes of making the division; the one is to sever it with a scalpel, and then to sufficiently sear the end of it so as to prevent a flow of blood, avoiding, however, to burn it to a cinder, as is sometimes done. The other, and in some respects the preferable method, is to employ an edged firing-iron, which is to divide it by little crucial sawings, so that, when the cord is separated, it shall not present a uniform divided surface, but ragged edges, which will more perfectly destroy the mouths of the vessels, and tend to lessen the chances of hæmorrhage. This done, loosen the clams sufficiently to observe whether there be any flow of blood; gently wipe the end of the cord also with the finger, as sometimes an accidental small plug gets within the vessel, which afterwards is forced out, and therefore had better be removed by this means and at this time. Retain a hold on the clams a few minutes longer; and while loosening them gradually, observing to have an iron in readiness again to touch the end of the cord, if any blood makes its appearance. Satisfied on this point, sponge the part with cold water, but by no means dash it over them, as has been done; neither is any external application necessary, still less any resin seared on the end of the cord, which can only irritate, and will never adhere. On the after-treatment much difference of opinion has existed, and even yet exists. The powerful evidence of accumulated facts has now convinced veterinarians of both the necessity and propriety of some motion for the newly-castrated horse as a preventive of local congestion; such practice is common in most countries but our own, and seems salutary in all. Hurtrel d’Arboval, thus impressed, recommends the horse, immediately after the operation, to be led out to walk for an hour, and it is a general plan in France to walk such horses in hand an hour night and morning. Mr. Goodwin, in proof of its not being hurtful, informs us, that whole studs of horses brought to St. Petersburgh to be
