contains an account of Bacteria, which may be read with the 

 greatest profit by those already familiar with the whole subject, but 

 it is written in such a manner that no cultivated reader who 

 desires information about Bacteria will turn to it in vain. 



It would be needless to attempt a calculation of the numbers of 

 botanical and other scientific books which have been designed for 

 the general educated public. The almost invariable result is, that 

 when an enlightened member of the public sits down to peruse 

 such a book with thankfulness in his heart that now at last he will 

 learn something fundamental about so-and-so, he begins exceedingly 

 comfortably and all goes well for a page or two. Then a sentence 

 is reached which has to be read again ; if he be persevering, index 

 or glossary are consulted and — welJ, the result is that he feels a 

 few minutes later he " would like his money back." The present 

 book not only contains, as has been said, the whole matter from the 

 author's point of view; it is not only a severely and profoundly 

 accurate book, but it is intelligible to the merest chemist who needs 

 biological information on the subject. "With this book, and with 

 Dr. Klein's ■ Micro-organism and Disease,' especially that portion 

 of it which deals with the methods of research, the student may 

 equip himself, for a few shillings, with the necessary fundamental 

 literature of Bacteriology. 



Prof, de Bary may be heartily congratulated on the successful 

 form of the English edition of his lectures, which conveys them to 

 all here "who are not strangers to the elements of a scientific 

 training.' ' 



The book contains, besides a good index, an excellent con- 

 spectus of the literature, with notes on it.
