study of plant biology on eminently sound lines ; he has 

 recognised the importance of bringing home to the 

 beginner the necessity of \dsualising the living plant as 

 a machine performing work and requiring energy.

■Geology of the Tertiary and Quaternary Periods, and the 

 PalcBontology, of the North-West Part of Peru. By 

 T. O. Bosworth, D.Sc, M.A., and others. (Mac- 

 millan & Co., 45s.) 



Beyond a few articles in magazines, little has been 

 •written about this interesting and economically important 

 territory in South America. The geological surveys which 

 Dr. Bosworth has carried out there in the last ten years 

 are pioneer work, and the descriptions and conclusions 

 therefrom, which make up four-fifths of his book, are 

 wholly new. The four parts of the book which contain 

 new scientific matter relate to the structure and strati- 



graphy of the Tertiary deposits, the geology of the 

 Quaternary period, the geology of the desert, and the 

 palaeontology of the Tertiary deposits. The first three 

 of these are by Dr. Bosworth, and the last by his four 

 collaborators. The fifth part is of a much more popular 

 character, and is a description of the occurrence and 

 exploitation of the petroleum in the district. This is 

 one of those books of which it may be justly said that 

 no expense has been spared in its production. It is 

 well printed, and very fully illustrated with 150 photo- 

 graphs, maps, and diagrams, and 26 plates. It is, 

 of course, a book for technical readers only ; a useful 

 addition to geological and oil-field literature. 



Elements of Plant Biology. By A. G. Tansley, M.A., 

 F.R.S. (George Allen & Unwin, los. 6d.) 



This book is intended primarily for medical students 

 and others who do not necessarily intend to continue the 

 study of botanv, but wh_> desire or are obliged to obtain 

 some elementary knowledge of plants, particularly in 

 relation to general biology. It will also be useful in the 

 highest forms of schools, but it is not a work for the very 

 young. It aims at providing a course of teaching which 

 shall be as interesting as possible, and shall serve to 

 introduce the student to the fundamental facts and 

 principles of biology, both as part of his training for life, 

 and more particularly as an introduction to the study of 

 medicine. It is based on the first portion of the course 

 in elementary biology at Cambridge (where the author 

 is University lecturer in botany), for the preliminary 

 examination in science and the first examination for the 

 M.B. degree. This portion deals mainly with plants 

 and serves to introduce freshmen, many of whom know 

 nothing whatever about the subject, to biology. It 

 differs from most textbooks of similar scope chiefly in 

 two ways. It devotes nrore space to biological facts of 

 general significance, illustrating them by a study of the 

 lower forms of plant life. Second, it introduces the 

 student early to the most important substances which 

 make up the body of the organism, and to a brief 

 consideration of some of the physical characters of organic 

 substances and of protoplasm. At the end of each 

 chapter are schedules of practical work, occupying about 

 two hours, based on those in use in the course at 

 Cambridge.
