location and distribution of the internal surface upon which moisture 

 might condense, and finally as to the manner in which moisture may 

 be held upon this internal surface. 



From this rather specific picture of the cotton hair structure it has 

 been possible to calculate moisture contents and swelling properties

 present a more comprehensive explanation of the change in the 

 relations between electrical resistance and moisture content of cotton 

 over the whole range of atmospheric humidity than that given in
