for it would be hard to accumulate too much knowledge of the so-called Fungi. 

 The pamphlet before u? is devoted to the Leueospori under the immense genus 

 Agaricus, and the species number just 80. Four good plates illustrate six new 

 species, all of Mr. Morgan's describing except the A. Morgani of Mr. Peck. 

 The species are arranged according to the Hymenomycetes Europceioi Elias Fries, 

 whose classical descriptions are also carefully translated, the local variations 

 and general observations being appended in the form of remarks, which are very 

 interesting. Lea's catalogue is the only other one covering this region, and his 

 34 Leueospori have been increased to 80 by Mr. Morgan, 5 of which he lias 

 described as new species, and 12 bear Mr. Peck's name as author. The second 

 paper will be devoted to the remaining Agariri. 



Tables for the use of Students and Beginners in Vegetable Histology. By D. P. Pen- 

 hallow, B. S. Boston. S. E. Cassino. 1882. 



This little book of some 40 pages is printed and bound in a most elaborate 

 way, the large type, broad pages, and stiff back, fitting it more for the library 

 than the laboratory. It is hardly fairly named, as it deals only with the micro- 

 chemistry of plants, and by no means presents the broad principles of vegetable 

 histology. It could be made useful under an efficient teacher, but then it 

 would hardly be needed ; but for an unskilled teacher, or one who is attempt- 

 ing self-instruction, it seems hardly the thing. There is given a list of reagents, 

 but with nothing practical as to their preparation or application. Then fol- 

 lows an account of the common "vegetable products," under which, among 

 others, we find grouped protoplasm, the nucleus, and silica. A better heading 

 would have been "cell-contents," which is used for Table I. The second table 

 is devoted to "Cellulose Forms," by which is meant the form and structure of 

 cells ; and Table III. is headed "Plant Products," which by no means includes 

 all the "vegetable products" mentioned in the text under that caption. In fact, 

 to the casual reader, it would seem rather difficult to draw the line between 

 "cell-contents" and "plant products," although a table is devoted to each. The 

 conception of the work is excellent, but the execution seems very imperfect.
