BOOK REVIEWS. 



Bulletin of the New York State Museum, lieport of the State 

 Botanist, 1898. By Charles H. Peck. AJhany, Univ. of the 

 State of K Y., 1899. Price 40 cents. 



The present report, which is dated October 1899, contains among 

 several interesting features, a list in parallel columns of 608 species 

 known to occur within the state which bear different scientific names 

 in Britton & Brown's Illustrated Flora and Gray's Manual. Mention 

 is also made of 46 species of fungi which are described as new. Several 

 pages are devoted to an interesting discussion of the flora of the open 

 summit of Mt. Marcy, an Adirondack peak 5,344 feet high and the 

 loftiest of the state. Descriptions of twelve additional edible mush- 

 rooms complete the pamphlet, the colored plates being issued separately 

 in folio forms. The report is one of the best of recent years. —

Pfeffer's Physiology of Plants. Second edition. Translated and 



revised by E. J. Ewart. Vol. I. Oxford. The Clarendon Press. 



Price 17.00. 



Professor Ewart has certainly rendered a very great service to 

 English speaking students by the translation of Pfelfer's splendid 

 work. From the appearance of the first edition in IS SO it has been 

 the standard, but the difficultv of the orioinal German has made its 

 use, until now, a matter of considerable difficulty. As Pfeffer took 

 occasion to say, this work is not intended as a text-book for beginners, 

 but as a hand-book containing a complete account of the present state of 

 our knowledge concerning the general processes of metabolism and 

 the sources of energy in the plant. Inasmuch as investigation is ad- 

 vancing rapidly along these lines new editions become necessary in 

 order to properly bring the sui)iect abreast of information. This has 

 been done both by the author and the translator, and it may be taken 

 as representing the present status of the subject. 



From the side of the book maker's art this volume is perfect. 

 The paper, typography and binding are ideal for a work of the kind, 

 although the consequent price may prove more or less of a drawback 

 to its widest circulation. — F. H. K.
