Inoculation to produce immunity from diphtheria, small- 

 pox, hydrophobia, et al., has been successfully practised 

 for many years, as also by veterinaiies as tests for tuber- 

 culosis. The procedure is in its infancy, as yet, but is one 

 of great promise, since it i's the cell which must be acted 

 upon, and the rapidly propelled blood, reaching it almost 

 instantly, comes in touch with its sentient surfaces. As 

 soon, therefore, as we can discover and compose regenerat- 

 ing substances, or those which will stimulate regeneration, 

 the blood-circulatory affords an efficient route to every 

 cell in the body. 



What these substances are, we do not yet know, whether 

 artificially propagated nuclein, or reagents which stimu- 

 late its growth in situ. But if anatomy and histology 

 offer us one hint more significantly than luiotlier, it is that 

 the blood may be made a breeding-ground for the regenera- 

 tion of the somatic cell. Five thousand well-equipped in- 

 vestigators, starting off with enthusiasm and rivalry to 

 study this problem, would hardly fail in twenty years to 

 set us far on the way to the control of all life. Wha-t 

 our rich men spend yearly in their vacuous craze for 

 horse-racing alone would more than equip and main- 

 tain these researches. Such inane squander and mis- 

 direction of the world's hard-earned money cries down 

 Heaven's condemnation. But they know not what 

 they do ! Misled and bewildered by erroneous creeds 

 and futile ideals, they know not how otherwise to
