 Where there is much wetness of surface and irritation, the 

 parts may with benefit be dusted from time to time with plain 

 flour, or I part of powdered alum to 6 of flour. Debility and 

 wasting is overcome with mineral tonics and cod-liver oil. 

 The diet should be plain, nutritious, but not stimulating. 

 Daily exercise should also be allowed. 



Chronic Eczema, though not accompanied by the same

 I have such a case in remembrance, wherein the disease of 

 the skin was rendered most distressing by its associations with 

 a kiud of cutaneous neuralgia ; and I have since seen several
