1. Importance of pure Air. 



Pure air is as important to the integrity of the blood as wholesome

The importance of pure air can hardly be adequately appreciated 

 without some knowledge of the course of the circulation of the blood 

 and also of the composition of the air. 



It is not, however, intended, either in this or any succeeding chapter 

 to enter into any minute descriptions of structures or processes ; but an 

 endeavour will be made to give concisely, and it is hoped suflficiently, 

 broad principles and facts which may enable the non-professional reader 

 to understand the subject refen-ed to. 



2. Circidation of the Blood.
