NEW PUBLICATIONS. 



MiJcrophotographie unci die Projection. By Dr. R. Nouhaus. 

 Halle a. S.: Wilhelm Knapp, 1894. Pp. 58; 5 illustrations. 

 Price 40 cents. 



This book treats microphotography in such a popular way 

 that even a beginner, by following the rules laid down, will 

 soon be enabled to produce satisfactory pictures. The second 

 part of the book gives a description of how to project prepared 

 microscopic objects on a screen. 



Twelve Edible Mushrooms of the United States, with Directions for 

 their Identification and their Preparation as Food. By Dr. Thomas 

 Taylor, Chief of the Division of Microscopy of the Department 

 of Agriculture. 



The importance of the subject need not be insisted upon to 

 the few who know how immensely superior the fresh American 

 mushrooms are to those imported from Europe — as Mr. William 

 Falconer of Glen Cove, N. Y., puts it, in a summary contained 

 in Dr. Taylor's pamphlet of a paper read before the Massachus- 

 etts Horticultural Society for February. " Many persons who 

 have used the tasteless, indigestible, putty-balls from imported 

 cans will repudiate the foreign article and accept no other than 

 the wholesome, toothsome and juic}' domestic product." In 

 this statement Mr. Falconer has reference to the time when, as 

 he foresees, the production will have been so increased as to re- 

 duce the price from a fictitious to a popular basis. Dr. Taylor 

 describes the following species : Lactarius deliciosus. Cantha- 

 rellus cibarius, Marasmius oreades, Hydnum repandum, Agar- 

 icus campestris, Coprinus comatus, Morchella esculenta, Cla- 

 varia cinerea, Clavaria rugosa. Boletus edulis, Lycoperdon gi- 

 ganteum, and Fistulina hepatica. All these species are shown 

 in colored lithographs and described sufficiently for their iden- 

 tification in the text, in which, moreover, directions are given 

 for gathering, preserving and cooking each one. In an appen- 

 dix the reader is instructed how to cultivate mushrooms, and 

 Mr. Falconer's description of a new species, Agaricus subrufes- 

 cens, is quoted.
