pennanent, but if it is malignant, generalisation will rapidly ensue. 



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 with 

 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- 

 seiir 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.
