Practical Botany for Beginners. ° 
By Prof. F. O. Bowser and D. T. Gwynne Vaucuan, M.A. 
Globe 8vo. 3s. 6d. 
GUARDIA N.—‘‘ We should say there is no more complete handbook published; it 
satisfies the supreme test, for with its assistance an absolute novice could procure and set 
up apparatus and teach himself, dispensing with oral instruction.” 
University Text-Book of Botany. 
By Professor DoucLas HouGHTon CamPBELL, Ph.D. 8vo. 178. net. 
ATHENZUM,.—‘*We may congratulate the author on the success of his attempt. 
There was no room for much novelty in the arrangement of materials, but the presentment 
of the details is concise, lucid, and up-to-date. It is, by reason of its condensation, not 
a book which we should place in the hands of a beginner, but to more advanced students 
it will be of very great value.” 
The Structure and Development of Mosses and 
Ferns. (Archegoniate.)

KNOWLEDGE.—“ Botanists should be grateful for this solid and comprehensive 
contribution to the literature of the Archegoniate series—the best that has appeared for 
some years. Prof. Campbell’s work will be long recognised as a standard one for students 
of the structure, development, and inter-relationships of the lowly but important families 
of plants described in it.” 
Lectures on the Evolution of Plants.

4s. 6d. net. 
ATHENAZUM.—“The present book is admirably adapted to convey a general know- 
ledge-of the subject, and to serve as an introduction to more recondite treatises, Not 
only does it pass in review the main groups of plants, but it deals also with such subjects 
as the geographical and the geological distribution of plants, the relationships of animals 
and plants, and the influence of what we used to call external conditions, but which is 
now universally spoken of as the ‘environment.’ ”
