176 SCIRRHOUS TESTICLES— CANCER. 



hazel nut, or a walnut, according to the size of the dog; first

 the neck with a bandage, to prevent the ointment from being

 as recommended under bronchocele. In some cases, mercurial 

 frictions have succeeded ; but, in default of these, proceed, with-

CANCER. 



I HAVE already stated that the virulence of the human car- 

 cinomatous ulceration is commonly wanting in what I call the 

 canine cancer ; for though spreading and incurable, as regards 

 its locality, yet it seldom extends beyond the precincts of the 

 gland it is seated in ; and if it ever makes further inroads, they 

 are slow, and not marked with constitutional derangement for a 

 long time : are seldom, if ever, translated to tlie lungs ; and do
