THE CAUSATION OF DISEASE. I 5 5 



do so now or a few months' hence, except for the temporary 

 inconvenience of the patient. Never was error more fatal, for, 

 apart altogether from the fact that chlorosis may immediately 

 predispose to other ills, such as gastric ulcer, and possibly 

 phthisis and heart disease, it stands to reason that rapidly 

 developing tissues must suffer considerably if they are bathed 

 for months together in thin watery blood. On no tissue will 

 this evil effect be greater than the nervous. I have seen cases 

 of chlorosis in quite young girls lasting over a year. Surely this 

 must lead to a permanent crippling of the young and rapidly 

 growing ganglion-cells!
