AND ITS RELATION TO ANIMAL LIFE 13 



likely to be immune than one whose blood is 

 defective. In other words, if my contention is 

 correct, the susceptibility to certain bacterial 

 diseases is directly traceable to the use of 

 chlorotic food. 



I shall develop this point at greater length, 

 and with reference to other bacterial diseases, 

 in later chapters, but it is sufficient for my 

 purpose here to have shown a direct connexion 

 between the bacillus and the chlorotic vege- 

 table. 



The variation in the supply of oxygen is an 

 important factor in health per se, but it 

 acquires additional importance from the fact 

 that the discharge of carbonic refuse varies 

 with it pari passu. 



The variation in the discharge of carbonic 

 debris derives its importance from the well- 

 known fact that carbonic debris is a food 

 for all pathogenic bacteria. 



Hence, if we assume that in normal animal 

 life, that is in every case where there is a nor- 

 mal haemoglobin, all this debris is discharged, 

 it is an easy deduction that the undischarged 

 debris will increase as the haemoglobin de- 

 generates from the normal until the maximum
