especially the teniporo-occipital radiations, and at the same time the amygdaloid 

 nucleus is uncovered, inferior and lateral to the basal ganglia, and the occipito- 

 frontal radiation may be seen. It is of interest to note that 4 of the 5 well 

 establislied arcuate fiber paths of the cerebrum connect the frontal lobe with 

 other parts of the brain. See plates I-V. 



The above outline of study is valuable because it combines approved 

 old methods with promising new ones. 



The gross morphology is described clearly and concisely, leading up 

 naturally to the more difficult dissection and sectioning methods. The 

 student moves along swiftly from the simple to the complex, beginning 

 with the spinal cord and terminating with the breaking up of the 

 cerebrum. The study begins with the analysis of the gross morphology, 

 then goes to the synthesis of the somatic and visceral systems, to end by 

 the analysis of the intricate mechanism of the cerebrum, having a simple 

 introduction and conclusion, but a complex body to the work. The time 

 given to the course is 120 hours, 6 mornings each week for 4 weeks, 

 after the preliminary, 1 hour each morning for two weeks. 



It is to be hoped that others will freely criticize and suggest regarding 

 the above plan of study, for only by tearing dowai and rebuilding can 

 perfection be attained in the art and the science of teaching, and thus 

 we may hoj^e to move foi-w'ard.
