PLAIN FACTS FOE OLD AND YOUNG 



These discoveries afford a thoroughly satisfactory 

 and scientific explanation of two facts which heretofore 

 have rested solely upon the basis of observation and 

 experience : 



1. That continence is favorable to physical vigor. 



2. That sexual intemperance is productive of ex- 

 haustion and debility to a most extraordinary degree. 



The influence of the sexual glands upon development 

 has been understood from very early ages. The influ- 

 ence of the removal of these glands in the equine or 



bovine race is well known. The 

 proudly arched neck, the grace- 

 ful roundness of trunk and 

 limbs, and the magnificent 

 courage and vigor of the stal- 

 lion, are not found in the muti- 

 lated animal. The massive 

 head and horns, the flashing 

 eye, the terrible majesty of the 

 bull, are never encountered 

 in the castrated animal of the 

 same species, the meek-eyed ox. 

 The differences in size, appear- 

 ance, and character which ex- 

 ist between the horse and the stallion, between the 

 ox and the bull, are purely the result of the loss of 

 the magic influence of the secretion of the sexual glands, 

 as a stimulus to development and a regulator of the 

 nutritive processes. 



The removal of the sexual glands before puberty, 

 or the failure of their development from any cause, 

 gives rise to similar differences in the human male. 

 A few years ago we saw an interesting example of this 

 fact. A young man between twenty and twenty-five
