Sturg^is's The Myxomycetes and Fungi of Colorado* 



This paper is No. i of a series by Ellsworth Bethel and 

 William C. Sturgis, entitled " The Myxomycetes and Fungi of 

 Colorado." In the series it is intended to cover the mycological 

 flora of Colorado, including the Rocky Mountain region, which 

 hitherto has been largely neglected by mycologists. In the 

 present paper nearly one hundred species and varieties of Myx- 

 omycetes are described. Preceding the descriptions are brief 

 notes on life history, collecting and preservation, microscopic 

 examination, and literature. It is intended that the paper may 

 serve as a beginner's guide, and the key is based upon the 

 synopsis of the orders and genera in Lister's Monograpli of the 

 Mycetozoa. C. Stuart Gager. 



Hanausek's Microscopy of Technical Products! 



This work is the result of the many years of labor of the dis- 

 tinguished expert, investigator and teacher. Dr. Hanausek, ana- 

 lyst of the Governmental Food Laboratory at Vienna. After a 

 brief introduction on the use of the microscope and microchemical 

 reagents, the authors discuss in nine chapters the following com- 

 mercial products: (i) starch and inulin ; (2) vegetable fibers, 

 under which heading attention is also given to the examination 

 of paper ; (3) animal and mineral fibers and textile fabrics ; (4) 

 stems and roots ; (5) leaves ; (6) flowers ; (7) fruits and seeds ; 

 (8) teeth, bone and horn ; (9) microchemical analysis for various 

 acids and minerals. 



The book is designed as a guide to the student entering the 

 field of technical microscopy and aims to familiarize him with 

 the methods of investigation and to prepare him for independent 

 work. It teaches the technical worker how to investigate micro- 

 scopically commercial raw materials with reference to their com-
