An obituary notice of Prof. Henry Copp^e by Mr. J. G. 

 Eosengarten was read by title. 



An obituary notice of Dr. W. S. W. Euschenberger was 

 read by Dr. Brinton. 



Mr. Bache read a paper for the Proceedin^js on " Personal 

 Equation." 



He said that, in order to fix the fact of his priority in what 

 he believes to be the discovery, that personal equation, or 

 relative reaction time of individuals, as it is variously called, 

 is related to race, he should like to state the final results 

 of some experiments which he has lately had made. From 

 auditory, visual, and tactile tests, applied to thirty-three differ- 

 ent individuals, represented by Whites, Indians and Negroes, 

 divided into their three classes, consisting respectively of 12, 11, 

 and 10 individuals, comprising in the aggregate 990 observa- 

 tions, giving the reaction time of these individuals by the sev- 

 eral tests, as recorded by electro-magnetic apparatus, are 

 derived the following final means, to the nearest thousandth 

 of a second. 



AUDITORY. VISUAL. TACTILE. 



White 147 165 136 



Indian 116 136 115 



Negro 130 153 123 



The superior quickness of the Negro, as compared with the 

 White is, therefore, so far as these figures show, given by the 

 following figures of differences. 



AUDITORY. VISUAL. TACTILE.
