This is a work which should be in the hands of every botanist 
who is interested in investigations into the deeper problems of plant- 
life. The first two chapters are devoted to brief descriptions of the 
microscopical apparatus necessary for his purposes, with directions 
for using them, and to the manner in which microscopical work 
should be performed. The translators have substituted descriptions 
and figures of American instruments for those of the Continental 
style described in the corresponding chapters in the German edition, 
inasmuch as the foreign apparatus are comparatively unused and 
unavailable in this country. 
The third chapter contains very full directions for the preparation 
of microscopical objects. The fourth and fifth chapters are devoted, 
respectively, to microscopical re-agents and microscopical investiga- 
tions of vegetable substances. In these two chapters, which consti- 
tute the most valuable portion of the work, the student will find a 
very large number of facts and hints that will aid him greatly in the 
practical performance of those delicate manipulations that he will be 
.obliged to master before he can become an expert in the histological 
investigation of plants. 
The book is very handsomely printed, and the illustrations are 
both numerous and excellent.
