NOTICES OF BOOKS. 



life-histories of the Schizoinycetes stands in the way of a satisfactory 

 botanical classification, but that is decidedly no reason for adopting 

 bases of arrangement which have been long discharged from 

 service in Botany. Dr. Zopf has divided his book into four sections, 

 dealing with the morphology, physiology, methods of investigation, 

 and systematic arrangement respectively. He divides the group 

 thus : — 



I. CoCCACEiE 



Gen. 1. Streptococcus. 



2. Merismopedia. 



3. Sarcina. 



4. Miciococcus. 



5. Ascococcus. 



II. Bactebiace^. 



Gen. 1. Bacterium. 



2. Spirillum. 



3. Leuconostoc. 



4. Bacillus. 



Gen. 5. Vibrio. 



6. Clostridium. 



III. Leptoteiche^. 

 Gen. 1. Crenothrix. 



2. Beggiatoa. 



3. Phragmidiothrix. 



4. Leptothrix. 



IV. ClADOTEICHE/E. 



Gen. 1. Cladothrix. 



The author, who, by the way, accepts the Spirilhim CholercB 

 Asiaticce (which is doubtless the defeated comma- shaped Bacillus 

 of Koch's researches), deals concisely with the pathological 

 literature. The book is clearly written, and excellently illustrated. 

 A very useful catalogue of the literature of the subject is to be 

 found at the end. G. M. 



Die Methoden der Bacterien-Forschung. Von Dr. Ferdinand Hueppe. 

 (Kreidel. Wiesbaden, 1885). 



Db. Hueppe, who is a pupil of Dr. Koch's, has gathered together 

 into a handy form a very useful body of information on the subject 

 of the methods of investigating Bacteria. Much of this information 

 has been collected from sources difficult of access, and the whole 

 has been judiciously arranged by the autbor, who shows a wide and 

 intimate knowledge of the methods in use. The methods of stain- 

 ing and cultivating, the principles of sterilization, the relation of 

 Bacteria to decomposition and to disease are very fully discussed, 

 as well as the general Biology of the group. The illustrations of 

 apj)aratus, &c., are a useful feature of the book. The author has 

 done excellent service in not only gathering together, but in 

 selecting the materials for a book which is sure to be welcome 

 among students of the important group of Schiwmijcetes. G. M. 



Text-hook of General Botany. By Dr. W. J. Behrens. Translation 

 from the second German edition revised by Patrick Geddes, 

 F.E.S.E. [Pentland, Edinburgh, 1885] . 



A Course of Practical Instruction in Botany. Part I. By F. 0. 

 Bower and S. H. Vines. (London, Macmillan & Co., 1885). 



Few German text-books of Botany better deserve translation 

 than Behrens', and very few have been better translated. Miss 

 Harris Smith and Mr. Geddes nre to be sincerely congratulated on
