xii Preface to the New Edition 



the viscose process has taken an increasingly important place 

 in industry, and, in fact, may now be regarded as a staple 

 textile. + The cellulose acetates are applied . in continually 

 increasing proportions for special purposes, and there is a very 

 definite position established for these derivatives in various 

 forms as substitutes for the better-known manufactures based 

 on nitro-celluloses, chiefly celluloid in its various forms of 

 solid and of sheet or film. 



The capital investments and interests involved in cellulose 

 industries are of enormous dimensions, and are increasing at 

 a rapid rat**- For information as to these the specialist 

 publications must be consulted.
