Tue Microscope IN Botany.1—This edition and translation 
differs in many important respects from the original, having been 
especially adapted by the American editors to the wants of botan- 
ical students in this country. The changes are most numerous 
in chapter 1, which is devoted to a discussion of the microscope. 
Here the student will find much valuable and interesting matter. 
We cannot refrain from quoting, for the benefit of our makers of 
microscopes as well as the younger botanists, the remark of 
Hugo Von Mohl: “The simpler the construction of the micro- 
scope is, the more easily and more quickly will one accomplish 
all the necessary movements. The more complicated the con- 
struction the more will they cost in time and reflection, and the 
more will the attention be distracted thereby during the observa- 
in vain to prepare a usable specimen ” (p. 8). 
The second chapter is devoted to accessories, and the third to 
the preparation of microscopic objects, both of which pertain to 
microscopy in general fully as much as to micro-botany. 
Chapter rv is devoted to the reagents to be used in the botani- 
cal laboratory. The treatment here is satisfactory, and reminds 
one much of Poulson’s Botanical Micro-Chemistry. 
In chapter v we find the book proper, to which all the pre- 
ceding chapters have been accessory and preparatory. Here are 
taken up the various substances to be found in the plant, ¢. £., 
cellulose, including wood and cork, starch, dextrine, mucilage, 
gum, inulin, sugar, albuminous matter, chlorophyll, the coloring 
matter of flowers, etc., etc. In all this portion of the book the 
treatment is such that the student cannot fail to obtain many use- 
ful suggestions and hints in his work.— Charles E. Bessey. 
Tue AMATEUR NATURALIST, Germanton, Phila. ; THE HOOSIER 
Philada.; THz Young MINERALOGIST AND ANTIQUARIAN, Whea- 
ton, Illinois—These periodicals are intended for the instruction 
and pleasure of the younger naturalists, and we welcome them as 
a useful agent in developing the taste for science which is so fre- 
uently seen among boys. Such publications serve to keep alive 
an interest which is often more or less extinguished with advanc- 
ing years and responsibilities, but which is of much value to the 
. A more general adoption of the scientific or positive 
method in thought and action is one of the anticipations of those
