NOTICES OF BOOKS. 



System der Bakterien. Handbuch der Morphologie Entioickelungs- 

 geschichte 7ind Systematik der Bakterien. Von Dr. W. Migula, 

 a.o. Professor an der technischen Hochschule zu Karlsruhe. 

 Erster Band, mit 6 Tafeln. Jena: Verlag von Gustav Fischer, 

 1897. 



Dr. Migula has earned the gratitude of those who, unable by reason 

 of the pressing claims of other work to cope with the hordes of original 

 contributions so rapidly following on each other's heels, yet desire to be 

 placed au conrant with the main lines of advance in bacteriology. He 

 has not attempted an easy task. The mere working through the steadily 

 increasing literature must have required an immense amount of perse- 

 verance, but he has succeeded in giving his readers a fair account of a 

 many-sided subject. Opening with an historical introduction, occupying 

 the first fifty pages or so, he proceeds to give a fairly detailed discussion 

 on points connected with the morphology and development of the organ- 

 isms themselves. The methods of growing the plants, and the varied 

 conditions of their life, including their influence on the substratum, 

 occupies the concluding chapters of a volume so full of information as 

 to cause one to express the hope that its promised successor will appear 

 as soon as may be. Dr. Migula is decidedly to be congratulated on this 

 first instalment of an important work. 



Views on Some of the Phenomena of Nature. By James Walker. 

 London: Swan Sonnenschein & Co., 1898. 



The general character of this book is sufficiently set forth in the 

 following extract, taken from p. 187 : — 



" Light is the combined Plasma of all the several substances which 

 are in the sun's pyrosphere in an incandescent state, and carried off by 

 a flood of force generated in, and ejected from the sun, and which com- 

 bination constitutes Electrogene ". 



A Text-book of Zoology. By T. Jeffrey Parker, D.Sc, F.R.S., and 

 William A. Haswell, M.A., D.Sc, F.R.S. In two volumes. 

 Pp. lvii., 1462. With 1 173 illustrations. Macmillan & Co. 

 Price 36s. net. 

 The appearance of this important work, for which many of us have 

 been eagerly waiting, will be hailed with pleasure, but not, alas, unmixed 

 with sorrow. For almost simultaneous with its publication we have to 

 record the premature death of one of its authors. The late Prof. 

 Parker's earlier works are well known and highly appreciated by all 

 students and teachers, and we believe that the present book, represent- 

 ing as it does the finishing and crowning work of a life devoted to the 

 furthering of biological science, will attain to an equal if not to a greater 

 degree of popularity than that enjoyed by his previous works. 



While we cannot avoid attaching this melancholy interest to the book 

 before us, in connection with one of its authors, we must, on the other 

 hand, congratulate Prof. Haswell on the completion of his great task.
