42, AN ELEMENTARY TEXT-BOOK OF BOTANY. 
Text-book and the Student’s Tewt-book. It strongly recalls the 
latter, of which it is ooh an abridgment, brought more up 
to date, with ‘‘the omission of certain difficult and debatable topics, 
such as, for instance. narene details of nuclear division, or the alterna- 
tion of generations in the Thallophyta.” Prof. Vines hopes at 
some future time to render the difference between the two more 
is done, the Student’s Text-book will probably fall into disuse, for 
the new book contains pr subject-matter for the majority of 
those who would buy o r the other; while as regards rf fficult 
and debatable topics it “a bets for the student to hear about these 
coins from his teacher. We are glad to note one alteration, 
mely, the apr ens of the section on Physiology ay the Anato- 
‘ibn instead of at the end of the book after the Systematic 
portion, as in the feet s Text-book ; except for this book 
runs on exactly the same lines as the larger work. Parts 
dealing respectively with external morphology and Gatatt and 
histology, are good introductions -to the study of one structure, 
while Part 3, on physiology, is excellent as far as it goes. We 
iss, however, from the latter, that side of the study of plant-life 
and which is perhaps the most attractive part o y, for it 
the study of plants living and growing out of doors. In fact, Part 3

in ol i groups ; the recent discoveries which have emphasized the 
pre s of Gymnosperms and Pteridophytes have caused the eleva- 
tion of : Gpnaivapeeies and Angiosperms, formerly regarded as sub- 
divisions of one eroup—Phanerogamia—into distinct groups, each

arranged under the four old colour-groups, while Fungi comprise

orders, and the transference of Kuphorbiacee from Disciflore to 
Monochlamydee. The systematic arrangement of this group is the 
least satisfactory partof the book. Owing largely to the work of 
the Berlin school, igaiee ane advance has been made in sys- 
tematic botany dur last few years; the classification both
