To understand how alcohol comes to be classed as a 

 narcotic, it is necessary to learn about a substance called 

 lipoid (Greek, lipos, fat ; eikos, like). 



" Within recent years a new sort of body substance has 

 been discovered, and has been elevated to first-rate im- 

 portance. This new class is termed 'lipoid.' Its impor- 

 tance is immense. It is quite as important in the body as the 



nitrogenous or albuminous 

 material which is present in 

 every living tissue. It is 

 very like fat in many re- 

 spects, but in other respects 

 it is different. It contains 

 nitrogen, which fats do not; 

 it contains phosphorus, 

 which fats do not; again it 

 mixes with water, which, as 

 is well known, fats do not. 

 It has certain remarkable 

 properties, in that it can 

 make certain bodies soluble 

 which are otherwise not 

 soluble. 



" The walls of practically 

 every living cell in the 

 whole body are made 

 chiefly of lipoid, and it is found that there are strands 

 of this material running through and through the sub- 

 stance of every cell. In fact, there is no region of any 

 cell in any part of the body that is without this material. 

 " Perhaps the largest accumulation of lipoid is that in 

 the nervous system. There is far more lipoid in the 

 brain than in any other tissue. If you examine a nerve, 

 or what physiologists call a nerve trunk, you will find

 point to the conclusion that intemperance
