AND ITS RELATION TO ANIMAL LIFE 51 



the whole chemistry of the animal can be 

 effected, hence disease. 



In the same Text Book, vol. ii. p. 781, we 

 find " It will be remembered ( 244) that 

 bile contains a distinct quantity of iron, which 

 probably has its origin in the iron thus set free 

 from the haemoglobin and retained in the 

 hepatic cell." 



From this it is a fair deduction that the 

 quantity of iron set free from the haemoglobin 

 will vary according to the percentage of iron in 

 the haemoglobin, and it is a fact that an 

 anaemic haemoglobin has a less quantity of 

 iron to set free than a normal haemoglobin. 



It follows, therefore, that blood rendered 

 anaemic by eating chlorotic food is likely to 

 produce a diseased liver a view which I 

 think is more in accordance with common 

 sense than that of those who hold that it is the 

 diseased liver which produces anaemia, which 

 is considered to be the case by some. 



In the same book, volume and page we read 

 " The hepatic substance is found to contain a 

 small quantity of iron sufficient to give the cells 

 a diffused dark colour when treated with
