March 2, 1874. 

 W. T. Harris, President, in the chair. 



The Recording Secretaiy being absent, R. Hayes was appoint- 

 ed to act pro tempore. 



Publications received, laid upon the table, and among them a 

 copy of Professor Broadhead's Geological Report, for which the 

 thanks of the Academy were voted. 



Judge Holmes spoke of the contents of some of the publications 

 received, and particularly of an article in regard to measurements 

 of the human brain which tended to show the effects of education 

 on the increase of the brain and especially of the frontal lobes. 

 A discussion followed on the distribution of the early races of man, 

 and the evidences of geology and philologv on the same subject. 

 Judge Holmes thought that the evidence of philology did not ex- 

 tend sufficiently far back to be of much value in the question of 

 the origin of man. Mr. Harris thought that, though the evidences 

 from philology dO not extend so far back as those from geology, 

 they do go back at least 13,000 years. He did not believe that 

 geology shows whether migration was from India westward to 

 Europe, or from Europe toward India. He was of the opinion 

 that philology shows the migration to have been from Europe
