246 FAT. 



" 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." From HUXLEY'S The Crayfish, as an Intro- 

 duction to the study of Zoology as modified by Sedgwick and 

 Wilson in their General Biology. 



It will be well here to recall some facts noted in connec- 

 tion 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 apparent. 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, and the general tone of the body 

 will soon be lowered ; for the health of the body as a whole 

 depends on the average condition of the cells composing the 

 body, just as the condition of any community depends on the 

 average condition of the individuals of that community. 



Fat. As a tissue fat serves as a stored-up food. The 

 camel's hump is a well-known instance. In some of the 

 savage races fat is stored in a very similar hump. But in
