6 QUATERCENTENARY STUDIES IN PATHOLOGY 



Viewed from the right side, the base of the tumour is closely applied

 surface there is an oval depressed area, 50 mm. by 38 mm. in size, the 

 appearance of which suggests an irregular mouth cavity. This cavity is 

 surrounded by fleshy flaps like lips, covered by skin externally and 

 mucous membrane internally ; while, again, inside these are firm con-
