ON NEURAL EXCRETION 85 



good and well, but if, after every legitimate effort towards 

 that end, it fails, then it behoves the directing partner no 

 longer to attempt the impossible, on the principle of 

 "putting new wine into old bottles," but to accept the 

 inevitable and become accustomed to work in "reduced 

 circumstances," which, in other words, means that a failing 

 material capital must not be destroyed at the expense, or 

 by means of, an artificially strengthened and accelerated 

 dynamic expenditure. 



We must, therefore, regard it as a sound principle not 

 artificially to overstimulate a failing brain and nervous 

 system by infusing into them alien dynamic influences, or 

 over-increasing the crippled output and exercise of ordinary 

 nerve energy, but rationally to slow down, husband, and 

 regulate the currents of physical and nervine work, in 

 accordance with the necessities of reduced organic ability, 

 by courses of graduated mental massage, so to speak, and 

 the dynamic influence of restricted nervine effort and 

 modified cerebration in other words, "spur not a done 

 horse," but give him food and rest first, and exercise 

 afterwards.
