JOUENAL OF THE ROYAL HORTICULTURAL SOCIETY. 



and found the directions such as to give very satisfactory results. 

 We thoroughly agree with Dr. Cavers as to the necessity for a pre- 

 liminary course in organic chemistry for the intelligent study of this 

 chapter. Chapters IV. to VII., on the physiology of plants, are very 

 clear and exceedingly good. We are pleased to note Dr. Cavers' 

 criticism of makeshift apparatus, and his advocacy of the use of special 

 ready-made apparatus such as Ganong's. 



In the life histories in Chapters VIII. to XII. we note the 

 original treatment of Pellia and Funaria in particular. 



We have tested the book, and can confidently recommend it as an 

 excellent practical botany. 



"Elementary Lessons on Plant Life." By D. G. Scott, M.Sc. 

 8vo. 219 pp. (Methuen, London, 1911.) 2s. e>d. 



This book consists of chapters re " Observations on the Flowering 

 Plant as a Living and Growing Organism." At the head of each 

 chapter are suggestions for work that is to be done before the chapter 

 is read. We were pleased to note that there are chapters on *' Plants in 

 Eelation to their Surroundings " and " Plant Families," and that the 

 latter precedes the former. 



We should hesitate to introduce seaweeds, and particularly mosses 

 and the field horsetail at so early a stage as Part II. of the book. 

 The tabular arrangement of experiments is very helpful in the hands of 

 a capable teacher, but should not be put into the hands of a scholar, 

 as is recommended in the Preface. As a guide tO' a teacher who has 

 very little knowledge of plant life it is of assistance. 



We notice several printer's errors in the Preface: (1) Warming's 

 ''Geology of Plants" should be, of course, Ecology of Plants"; 

 (2) Willis's " Flowering Plants and Ferns " is mentioned twice in the 

 list of authorities consulted. 



" Second Stage Botany." By J. M. Lowson, M.A., B.Sc. 8vo. 

 644 pp. (University Tutorial Press, London, 1911.) 4s. 6d. 



This book has been written to meet the requirements of the Board 

 of Education Examination in Second Stage Botany; but we think 

 the section on Ecology, consisting of only thirty-seven pages of matter, 

 would require supplementing. The diagrams, which are quite a feature 

 of the book, are very clear and able to be easily reproduced. The life 

 histories of the lower cryptogams are graphically represented. We 

 wish the chapter on " The Eelationship between Vascular Cryptogam 

 and Flowering Plant " had been more fully treated. 



"A Text-book of Botany for Colleges and Universities." By 

 Members of the Botanical Staff of the University of Chicago. (Ameri- 

 can Book Company, New York.) 



Vol. I., Part I., includes Morphology, and Part II., Physiology; 

 Vol. II. is devoted to Ecology. Morphology is represented by brief 

 descriptions of types of all the groups of Cryptogams (pp. 1-170) and 

 Gymnosperms (pp. 180-228). In Angiosperms we have details on the
