AND ITS RELATION TO ANIMAL LIFE 99 



fungi and what we look upon as ordinary 

 plants, is that the fungi contain no iron or 

 nitrogen, while these constituents are essential 

 to ordinary plant life. 



It is known that iron and nitrogen are fatal 

 to fungi, therefore the more iron and nitrogen 

 animal life takes up in its food the more likely 

 it is to be immune to bacterial diseases. 



(1) Because it will have a richer haemo- 

 globin, which takes more oxygen into the system 

 and discharges from the system more carbonic 

 debris, which is a natural food of most if not 

 all pathogenic bacteria. 



(2) Such a food will contain more carbon, 

 so that there will be more sugars, fats, and 

 proteids. 



(3) In a blood rich in haemoglobin, there 

 being more oxygen, it follows there will be 

 more ozone, and ozone is fatal to pathogenic 

 bacteria. 



(4) Proteids are considered fatal to patho- 

 genic bacteria, and as there would be more 

 proteids in a blood rich in haemoglobin than 

 in an anaemic blood, it follows that a blood 

 rich in haemoglobin would be more immune 

 to pathogenic bacteria than an anaemic blood.
