were preparing the material for further and higher work. It is 

 somewhat amusing, however, to recall how many of them resented 

 the demolition of their "species," and how reluctantly they received 

 the deductions from " sterilizing," " cultivating," and " infecting." 

 This has passed away, and the biologists are in the ascendant. 

 The most eminent amongst these, especially in relation to the 

 UredinecB, was the late De Bary, whose results Mr. Plowright, in the 

 main, has followed ; in the UstilaginecB the work of Von Waldheim, 

 Brefeld, and Schroter has been utilised : but the author has added 

 the results arisiug out of " between nine hundred and a thousand 

 experimental cultures" of his own. 



It is not possible in the space at our command to give an 

 analysis of the contents, but a general notion of the book may be 

 conveyed in a few words. About a third of it is devoted to a clear 

 and precise description of the mycelium of the UredinecB ; what is 

 known of the spermogonia, and so-called spermatia, about the 

 function of which latter much doubt still hangs ; the secidiospores ; 

 the uredospores ; the teleutospores ; heteroecism ; mycelium of the 

 lJstilaginc(B ; formation and germination of the teleutospores of the 

 last-named ; and their infection of the host-plants, concluding with 

 the details of artificial spore-culture, and infection. The classifi- 

 cation and description of species occupy 110 pages, and the remainder 

 contains a reprint of the Barberry Law of Massachusetts, a glossary, 

 a list of authors quoted, and a description of the eight excellent 

 lithographic plates with which the volume is illustrated. 



While we speak highly of the author's share in this book, and 

 strongly commend it to the student of mycology as a most useful 

 monograph, we must not omit to express our praise of the manner 

 in which the publishers have done their work. A clear type, good 

 paper, and admirably executed plates, which do full justice to the 

 drawings of the author, add greatly to its value ; but as every critic 

 must have a fling at something, we conclude with an unqualified 

 condemnation of the binding, which, though remarkable, is neither 

 ornamental nor useful. Wllliaji PmLLips.
