Practical Plant Biology. Henry H. Dixon, ScD., F.R.S. 291 

 pp. Illustrated. Longmans, Green & Co. $1.75. 



It is interesting to get a book from the other side of the Atlantic 

 showing us how they are teaching sciences over there. Dr. Dixon 

 is Professor of Botany in the University of Dublin and Director 

 of Trinity College Botanic Garden in Dublin and this book covers 

 a course of elementary lectures on the general morphology and 

 physiology of plants which he gives to his students. The book 

 impresses one with its logical arrangement, scientific accuracy and 

 carefulness of detail. It consists of 30 chapters, each a lecture on 

 some topic beginning with the microscope and how to use it, then 

 follows chapters on the structure of a cell, Saccharomyces Cerevisae 

 Chlamydomonas, Bacteria, and so on up through the plant world 

 to Pinus Silvestris and Scilla Nutans closing with one lecture on 

 heredity and one lecture on evolution. At the end of each lecture 

 is an outline for the practical laboratory work to be done in con- 

 nection with it. The book is clearly written, straight-forward, 

 technical, scientific and is sure to prove most useful to those who are 

 teaching College Biology. Teachers of Biology in High Schools 

 will find it a valuable reference book. 



Elementary Industrial Arts. Leon Loyal .Winslow. 335 pp. 

 Illustrated. The MacMillan Company. 



The Industrial Arts have to do with Nature's products in one 

 way or another. To the eager, intelligent young naturalist nothing 

 can be more edifying than to learn how man has used Nature's 

 resources in building up civilization; to such this volume will 

 prove a revelation full of interest. Not only does it describe in- 

 dustrial processes, but it also gives practical directions for the con- 

 struction of different objects in each of the industries discussed. 

 At the end of each chapter is a poem and a list of books relating to 

 the topics. The author is a specialist in drawing and industrial 

 training in the N. Y. State Department of Education. The
