 first greatly elongated, and its ganglia imperfectly covered, the cra- 

 nium must then also have a correspondingly elongated form. 



"2. On the Antrum Pylori. 



" I have now for some time directed my attention to the determi-

 more convinced that the antrum pylori of the older anatomists 

 (' Pfortnerhohle ' of the Germans) is really a special compartment

 distinguished by greater thickness of its muscular coat, more strongly
