position and suitability for technical purposes, thus enabling him 

 to reach practical conclusions. The origin, harvesting, prepara- 

 tion and utilization of material are also briefly considered when- 

 ever the methods of preparation have an influence on the struc- 

 ture of the raw material. 



The English edition has been improved by the introduction of 

 over forty new cuts. The drawings by Winton and Barber are 

 a decided improvement over many in the original work which 

 are occasionally so diagrammatic as to be almost misleading. 

 Note should also be made of the very considerable additions to 

 the chapter on textile fibers and of the discussion of commercial 

 timbers which has been revised and extended so as to include 

 the most important North American species. 



Noteworthy features of the book are the citations of the liter- 

 ature dealing with the various topics treated and the attention 

 that is given to the solution of purely practical problems. Men- 

 tion should also be made of the discussions of the more impor- 

 tant morphological and biological features of the various organs 

 and structures studied so that the student begins his examination 

 of the commercial products with an understanding of the nature 

 and origin of the various cells and tissues with which he is deal- 

 ing. While in some minor respects this treatment is not in accord 

 with present day botanical teaching, it will be conceded that 

 the presentation has been made with a clearness and conciseness 

 of statement and with a simplicity and consistency of terminology 

 that may well serve as models for future authors. 



Considering the range of the work, the authors have been 

 remarkably successful in handling the various topics and have 

 furnished to technical microscopists a timely and valuable text- 

 book. Carlton C. Curtis.
