Dr. Kirchner's book deals with diseases due both to animal and veg- 

 etable parasites. Its statements are reasonably accurate and it is so 

 arranged as to greatly facilitate identification of diseases. No illus- 

 trations. 



eases and brief mention of many others. It was the first book of its 

 kind to pay much attention to bacterial diseases of plants. Its state- 

 ments are frequently inaccurate and the 17 plates illustrating fungi 

 and fungous diseases are poorly executed and add nothing to the value 

 of the book. 



Prof. Ward's little book is by far the best thing in English. It dis- 

 cusses only a few diseases and all of these in a very elementary, popu- 

 lar way, but there are ma stions, and the facts which 

 are given are usually stated accurately. There are 53 text figures and 

 a brief index. A book of about the same size and style by the same 

 author, on Timber and Some of its Diseases, (1889) makes a good com- 

 panion volume. 



Dr. Ludwig's book is uneven in its make up, some parts being quite 

 free from erroneous statements and others, those dealing presumably 

 with the subjects least familiar to the author, needing careful revision. 

 The book certainly deserves a second edition. From the pains taken 

 to say something about everything, it is perhaps more generally useful 

 than any of the preceding or than the following work. 



Dr. Tubeuf 's book is very attractive. The type is large and clear, 

 and the unhackneyed character of the illustrations, many of which 

 were prepared expressly for this work, i3 especially commendable. 

 The treatment of certain subjects indicates that the author depended 

 upon imperfect reviews rather than on the original papers, e. g., Wak- 

 ker's bacterial disease of hyacinths, and Mayer's mosaic disease of 

 tobacco ; but the book as a whole has not been read carefully enough 

 to warrant any extended criticism. 



Dr. Frank's book is the second revised edition of his well known 

 handbook, Die Krankheiten der Pfianzen, published in 1880, and now 

 sadly out of date. Much new matter has been added and an earnest 

 effort made to bring the subject up to date. This has succeeded as 

 well, perhaps, as the rapidly growing state of the science will admit. 

 The first volume deals with non-parasitic diseases ; the second with fun- 

 gous parasites. Most of the figures appear to be old, and the letter 

 press is indifferent. 



Dr. Prillieux's book is attractive in appearance, but some of it tt 

 sketchy and rather unsatisfactory, and due credit is not always given.
