its simple form to vacuolated cells, hut as most plant-cells are 
vacuolated the range of its applicability is not inconsiderable. 
Nothing that has been said has yet convinced me that the model 
will have to be discarded, though it will certainly need to be 
modified and complicated as our knowledge increases.

“ Bot:iny of the Living Plant,” by F. O. Bower, Sc.D., F.R.S , Regius 
Professor of Botany in the University of Glasgow. Pp. X. and 580, with 447 
figures in the text. Macmillan & Co., 1919. Price 18s. 
T HIS is the first general presentation of the elements of 
botanical science by a leading British botanist that has 
appeared for a very long time. It is framed, according to the 
author’s preface, on the lines of the annual course of elementary 
lectures on botany given in the University of Glasgow for more than 
thirty years. This course has been constantly remodelled and 
developed, and is now recast in the form of a series of self-contained 
essays with additional facts and some fresh subject matter. The 
material is throughout, says the author, such as will be reckoned 
elementary, but “ elementary and fundamental,” he adds, “ should be 
held as equivalent terms when applied to those facts and principles 
upon which a Science is built.” We may therefore fairly consider 
that this book contains, in the author’s judgment, the fundamental 
facts and principles of modern botany, which should, first of all, be 
presented to the attention of the student. 
The plan of the book as regards about half of its contents is 
somewhat unusual, and as the author remarks, will probably be 
criticised. After a short introduction and a substantial Division I 
(280 pages) which deals with the life history, anatomy and 
physiology of the seed plant along familiar lines, the author takes
