BOTAIVY. 



A Text-Book on Botany. 



By DR. EDWARD STRASBURGEB aided by DRS. NOLL, SCHENCK and SCHIMPEB. 



"To give a volume this desig- 

 nation is to doom it beforeliand to 

 exclusion from the hands of the 

 general reader. 



Perhaps the few words which 

 follow may do something to avert 

 from the charming treatise men- 

 tioned at the head of this article a 

 fate so undeserved. In the first 

 place, the whole appearance of the 

 work is attractive ; in the second 

 place, this attractiveness of aj)pear- 

 ance is associated throughout with 

 a most skilful presentation of fun- 

 damental facts and essential prin- 

 ciples. The translation is clear 

 and strong, and remarkably free 

 from slips of any importance. —

"The volume in its German 

 dress is so well known to botanists 

 that it is quite needless to speak of 

 its merits. Perhaps no man living 

 is better prepared than Dr. Stras- 

 burger to undertake the presenta- 

 tion of the portion of the work 

 which deals with the internal mor- 

 phology of plants. Certainly no 

 man has a better knowledge of the 

 structure of the cell, and the many 

 changes which it undeigoes in con- 

 stitution and form. "— Seiewee.

 siology.
