AND ITS RELATION TO ANIMAL LIFE 6l 



" Now oxygen appears to be capable of 

 assuming the ozonized condition under various 

 conditions, the principal of which are the 

 passage of silent electric discharges, and 

 the contact with substances (such as phos- 

 phorous) undergoing slow oxidation in the 

 presence of water." 



Again, as oxygen appears to be capable of 

 assuming this ozonized condition in the pre- 

 sence of phosphorus, to say nothing of iron, 

 it is easy to understand how the normal animal 

 would be likely to have more ozone than the 

 abnormal. 



The value of oxygen, or more properly ozone, 

 as conveying immunity, is recognized by many 

 authorities. Thus Dr. Henry Day, in Ozone in 

 Relation to Health and Disease, says

 between a deficiency of ozone in the air and the 

 occurrence of epidemic cholera," etc., and goes

 dead organic matter with great rapidity." 

 He adds : " There is much discussion as to
