220 THE SKULL. [chap. xiii. 



The mandible has, rather behind the middle of each 

 ramus, an oblong expansion for a horny tooth, corre- 

 sponding to that on the maxilla. Behind this it curves 

 gradually upwards to the expanded and transversely ex- 

 tended articular surface. There is no distinct angle, the 

 coronoid process is small and directed much inwards, and 

 on the external surface there is a very deep masseteric 

 fossa. Anteriorly the rami of the mandible have a very, 

 slight symphysial connection, in front of which their ex- 

 panded, flattened terminations again diverge from each 

 other. The apertures for the entrance and for the exit of 

 the branches of the inferior dental nerve are remarkably 

 large.
