Practical Plant Physiology. An Introduction to Original Research for 

 Students and Teachers of Natural Science, Medicine, Agriculture 

 and Forestry. By Dr. W. Detmer, Professor of Botany in the 

 University of Jena. Translated from the second German edition 

 by S. A. Moor, M.A., Principal of the Gorasia College, India. 

 London: Swan Sonnenschein & Co. New York: The Macmillan 

 Co., 1898. 



Those who have used Prof. Detmer's book will be glad to see an 

 English translation which will render it available for the many students 

 who are unable to read German. It must be confessed that the trans- 

 lation itself is not very attractive, and although this does not perhaps 

 affect seriously the value of the book as a working guide, it greatly 

 detracts from the pleasure of reading it. 



It is not without some feeling of melancholy that one reads that 

 the book is intended for those (amongst others) interested in Medicine, 

 Agriculture and Forestry. Most of those who devote themselves to the 

 two last-named pursuits in this country would consider such a course to 

 be a pure waste of time; and with the modern contraction of the liberal 

 scientific education which used to form part of the medical curriculum, 

 it is to be feared that but few students in this profession will have much 

 use for the book. But for those who are really interested in Physiology 

 in the widest sense, Dr. Detmer's book provides a good introduction in 

 so far as its relations to plant life are concerned. 



Algemeine Physiologic, Ein Grundriss der Lehre von Leben, von Max 

 Verworn, a. o. Professor an der Med. Facultat der Universitat 

 Jena. Zweite neu bearbeitete Auflage, mit 285 Abbildungen. 

 Jena: Gustav Fischer, 1897. 



To many people the appearance of a new edition, enlarged and 

 improved, of Verworn's Algemeine Physiologie will come as a welcome 

 addition to physiological literature, and even those who do not sym- 

 pathise with the author's views will admit the interesting nature of the 

 book. Of course in a work embracing so wide a field as the present 

 volume of about 600 pages, the method of treatment is necessarily 

 somewhat sketchy and unequal, but in spite of this the large amount of 

 original work and of suggestive points of view will certainly assure for it 

 a welcome at the hands of those who are interested in the physiological 

 phenomena of living protoplasm. 



Organographie der Pflanzen, insbesondere der Archegoniaten und 

 Sameupflanzen. Von Dr. K. Goebel, Professor an der Universitat 

 Miinchen, Erster Theil. Algemen Organographie, mit 130 

 Abbildingen im Text. Jena: Gustav Fischer, 1898. 



Prof. Goebel's book is one which should appeal to a wide circle 

 of readers, for it provides a clear and connected exposition of the 

 new vegetable morphology, in which the old formal treatment is almost
