180 THE AMERICAN MONTHLY. [June. 



Chicago Academy of Science, Microscopical Section. 



At the last meeting of the Section of Microscopy of the 

 Academy of Science Dr. W. H. Knap was elected chairman, 

 and Prof F. L. Morse was elected recorder for the ensuing year. 

 Mr. H. L. Tolman, the retiring chairman, delivered a most in- 

 teresting talk regarding his trip to Europe last year under the 

 auspices of the World's Fair authorities. He was assured of a 

 large exhibit of microscopes and accessories from the leading 

 foreign makers. This exhibit will be classified and exhibited in 

 the space secured by the Illinois State Microscopical Society and 

 will be under the care and supervision of the section of microscopy 

 of the Academy of Science, which was formerly the Illinois State 

 Microscopical Society. Permission was freely given by all the 

 prospective exhibitors to have stands and accessories shown and 

 used at the meetings of the section. When it is considered that 

 Powell & Leland, Zeiss, Nachet, Ross, Seibert, Lutz and other 

 European makers will send their finest productions here, not ex- 

 cepting Zeiss' famous objective of 1.63 n. a., and that we shall 

 have the privilege of examining them, it is not at all improbable that 

 next year will be one of great interest to microscopists. — Itt- 

 qui'sitor. 



NEW PUBLICATIONS. 



Primary Microscopy and Biology. B}- Albert Schneider, 

 M. D. 8vo, 100 pp., 20 cuts. Price $1. 



This book will answer as a guide for any beginner, as it is 

 strictly elementary and contains a little of everything. A dozen 

 pages are devoted to mathematical demonstrations of the physical 

 properties of lenses. These pages could easily have been omitted, 

 as beginners will not feel much interest therein. Another dozen 

 pages contain necessary descriptions of microscopical apparatus. 

 In another chapter are some discussions of life and of the ground- 

 work of biology, which are interesting for novices, and intended 

 as introductory to some simple microscopical experiments. 



Directions for elementary microscopical work upon starch, 

 pollen, yeast, insects, amoeba, and vegetable tissues constitute the 

 most important parts of the book. A chapter on vegetable his- 

 tology is very good. A dozen useful formulae are labelled 

 '• recipes," and an analytical table of contents placed at the end 

 of the book is misnamed "Index." 



The printer made a good many blunders, a part of which are 

 noted in an " errata " sheet. 



The author is modest, claims but little, and so gives all that 

 he pretends to give. 



Some Features of the World's Columbian Exposition. Qiieen 

 & Co., Phila. 

 This is a neat brochure of 16 pages designed to advertise their 

 exhibit.
