Mr. Bache went on to say that, as a paper by him on the 

 subject had been sent to a scientific magazine for publication, 

 he did not deem himself at liberty to add more than that he 

 believes that, other things being equal, the lower the race the 

 quicker is the reaction time. He accounts, he said, for the 

 superiority in quickness of the Indian over the Negro by 

 recognizing that the life of the Indian for thousands of years 

 promoted quickness of reaction, while that of the Negro has 

 tended to slowness. According to his view, he added, the 

 more intellectual the development, the slower ought to be the 

 reaction in all but the product of the higher thought. So far 

 as the observations presented show, the most intellectual of 

 races, the White, exhibits by far the slowest reaction time.
