hess is to promote the movement of fresh air. Foul and 
dark habitations interfere with true ventilation. The 
system breathes the poison thus generated, which acts as 
a powerful sedative on all the functions of animal life, 
predisposing it to diseased conditions. The system, in 
other words, acts like a sponge, and constantly imbibing 
impure elements, becomes fertile soil in which the seeds 
of disease may find the needful sustenance of their nature. 
Regular Exercise in the Open Air, apart from actual 
work, is essential for the promotion of organic function, 
many varieties of which are going on incessantly, besides 
eating and drinking. Food and exercise produce waste, 
the latter being mainly essential in the process of 
eliminating the waste, as the result of consumption of 
the first. Systematic Feeding is also essential. The

Proper food, water, and rest, will often do more good 
than medicines, which should never be given without a 
clear knowledge of the requirements of the case and 
their suitability for it. reguent and Indiscriminate 
Drugging is the basis on which blatant quackery thrives. 
Those who practise the first are responsible for the latter, 
and have no cause to complain when their malady be-
