It is worth noting that artificial silk, made by Chardonnet and others, 

 now often forms a part of some kinds of silk goods. A company is being 

 formed in this country to manufacture artificial silk under the Chardon- 

 net patents, the mill to be erected at Paterson, X. J. (See under Arti- 

 ficial silk in this work.) 



In closing. I may refer to a few works containing descriptions of the 

 fibers commonly employed in commercial industries. Very few books 

 have been published relating exclusively to fibers, and especially in 

 this country. In most books on dyeing, some description of the mate- 

 rials employed is prefixed, usually of a very superficial character: but 

 there are no special American publications on the technology of fiber 

 work. This list must be understood as including only the more impor- 

 tant publications on this subject. See in list of authorities William 

 Crookes, Knecht Rawson and Loewenthal, Yetillart. Thomas Christy. 

 Leo Tignon, F. H. Bowman, Julius Sachs. Griffin and Little, Edson 

 S. Bastin. and Cross and Bevan. Yetillart's work is the most thorough 

 that has been published, up to the present time, as regards the identi- 

 fication of libers by means of microchemical read ion--. Some of the 

 matter, together with information on a large number of new fibers, is 

 incorporated in the work by Thomas Christy. The Text-Book of 

 Botany by Julius Sachs is one of the highest authorities on the 

 structure of plants.
