Before interfering surgically, however, it is essential to examine the inguinal, pelvic, and sublumbar lymphatic glands, to make sure that they are not affected. If they prove to be already invaded, an operation should be avoided. Even despite such precautions and the apparent absence of any glandular infection, operation may be followed by generalisation in a few months, although for a short time the con- dition may seem to have greatly improved. No special indications need be given beyond those sug- gested as necessary in dealing wdth all kinds of tumours, whatever their nature. The skin should be freely divided, that the tumour may be thoroughly dissected out and no fragments be overlooked. The mass of the tumour having been dissected free, the ecra- seur is applied to the pedicle or the cord. Enucleation of the tumour may be very difficult on account of the presence of numerous ramifica- tions or attachments, but the closest attention must be given to removing every fragment if a fresh local growth is to be avoided. In the event of fragments being left, a fresh growth is certain to occur. Generalisation, which may extend to all the viscera (lymphatic glands, liver, spleen, lungs, pleura, peri- toneum, heart, etc.), is indicated by rapid wasting, fever, acceleration of breathing, digestive disturbance, and sometimes coughing, etc. Local new growths assume the form of ulcerating swellings. In practice, if the general condition can be improved for a short time, it is advisable to slaughter the animal.
