How do you treat carcinomata ? 



Early extirpation with, the knife. The best results give 

 those abont the anus, membrana nictitans, skin, penis, mam- 

 mary gland and testicles. The operative treatment of those 

 of the sinuses of the head is very unsatisfactory ; this refers 

 also to the removal of the thyroid gland. 



In pet dogs with inoperable carcinomata, it would not be 

 out of place to inform the owner of the possibility of an 

 -infection. The operating surgeon should take care of him- 

 self, as it is a fact that a number of veterinarians belonging 

 to our times have succumbed to carcinomatosis.
