THE EVOLUTION OF THE CEREBRAL HEMISPHERES. 337 



2. Upon Golgi or Weigert sections study the forebrain tracts in the 

 selachian and amphibian brain and if possible in the brain of a small 

 rodent, bat or mole. 



3. If material is available, study with the aid of Smith's descriptions 

 the history of the hippocampus and the fornix system by means of 

 dissections and Weigert sections of the brain of the opossum, bat, 

 mole, guinea pig, rat, rabbit, and cat.
