Lecture was given by Dr. John Comstock, of the South Western 

 INIuseum, on the "Aboriginal Man of North America." This lecture 

 was most interesting and greatly appreciated by the large audience 

 present. In the discussion which followed, the many questions 

 answered by Dr. Comstock proved him to be a complete master of 

 the subject. The lecture was illustrated by textile fabrics, weapons, 

 and utensils loaned for the occasion by the Southwestern Museum. 



May 27, 1920. 



Lecture was given by Dr. R. W. Bowling on "The Human Cere- 

 bre-Spinal Axis in its relation to conduct." Dr. Bowling illustrated 

 this lecture by casts of sections of the human brain and a relief plan 

 of the spinal column showing in detail the various nerve off-shoots. 



Dr. Bowling treated this subject anatomically, in a masterly 

 manner, and in his ethical deductions he revealed a largeness of tol- 

 erance and charity toward erring human nature that was most ap- 

 pealing. The audience evidenced their approval of the lecture in 

 the applause which greeted him at its close.

Lecture was given by Dr. F. C. Clark, subject being "The Evo- 

 lution of Birds from Jurassic Time to the Present." This lecture 

 v.-as illustrated with many bird specimens from the South Sea Islands 

 and the eastern South American coast which added great interest 

 to the meeting as w-ell as serving to elucidate points of the lecture 

 very forcibly. Models of other birds, both actual and hypothetical, 

 in wood carvings, prepared by Dr. Clark, were used in his illustra- 

 tions as well as the skeletons of birds. Mr. Keese, Treasurer of the 

 Southern California Academy of Science, announced, amid much ap- 

 plause, that Dr. Clark had that day been elected President of the 

 Academy for the ensuing year. Announcement was made that no 

 meetings of the Biological Section w'ould be held during July and 

 August and that due notice w-ould be given of the September meet- 

 ing.
