reproduction to a time considerably after the 

 attainment of the power of reproducing. 



With horses we investigated the manner 

 in which energy gets into the muscles in a 

 form to produce fast trotters; with dogs we 

 investigated that combination of muscular 

 and mental energy which goes to make the 

 champion setter; with cows we investigated 

 that energy in the secretory organs which 

 is involved in the production of milk; with 

 men we will investigate that form of energy 

 which produces mental power and mental 

 characteristics. 



Famous men are usually men of great in- 

 tellectual power, but fame does not always 

 rest on intellect. The Siamese twins were 

 famous but not for their mental power. The 

 men used in this investigation are the famous 

 men of the world, due notice being taken of 

 whether the fame was for brains or some- 

 thing largely independent of brains. Also, 

 the investigation will be directed to the type 

 of intellect, whether military, artistic, practi- 

 cal, or philosophical.
