embodiment of restless energy, where the swift stream 

 hurrying from the falls is compelled to make a sudden 

 turn toward Lake Ontario. 



" However changeful in the contour of its crest, this 

 wave has been visible, approximately in the same place 

 and with the same general form, for centuries past. Seen 

 from a mile off, it would appear to be a stationary hillock 

 of water. Viewed closely, it is a typical expression of the 

 conflicting impulses generated by a swift rush of material 

 particles. 



" Now, with all our appliances, we cannot get within 

 a good many miles, so to speak, of the living organism. 

 If we could, we should see that it was nothing but the 

 constant form of a similar turmoil of material molecules, 

 which are constantly flowing into the organism on the 

 one side and streaming out on the other." 



Importance of Renewal of Blood and Lymph. It 



will be well here to recall some facts noted in connection 

 with the study of the blood and lymph. We then learned 

 that the lymph (the supply and renewal of which depends 

 upon the blood) surrounds the individual cells which make 

 up the tissues of the body ; and that, to a certain extent, 

 every cell lives an independent life, each taking its nourish- 

 ment directly from the lymph around it. The importance 

 of an abundant supply of good lymph is now more ap- 

 parent. If digestion is not good, or the food be insufficient 

 or of poor quality (whether naturally or from being badly 

 cooked), good blood cannot be made, and the lymph will 

 not be good. The cells are more or less starved, or 

 poisoned if wastes are not properly removed, and the gen- 

 eral tone of the body will soon be lowered ; for the health 

 of the body as a whole depends on the average condition
