leaves is not strongly developed, but nevertheless persists on 

 the lower surface of the mature leaves, especially on the veins. 

 The fruit is abundant and resembles in size that of V. corym- 

 bosuin. In color, however, it is much more variable, ranging 

 from dark -blue with a little bloom to blackish with no bloom, 

 thus showing a very similar variation to that exhibited by 

 the common huckleberry \Gayliissacia baccata (Wang.) K. 

 Koch]. 



Judging from the original description of V. virgatwn by Aiton 

 (Hort. Kew. 2: 12) written in 1789, the plant intended to 

 to be named cannot be told with any certainty, but in Watson's 

 Dendrologia Britannica (/>/. jj) there is a good plate of the plant 

 cultivated in Great Britain under that name — evidently the same 

 species to which the name is applied in America. The exten- 

 sion of its range northward into New Jersey and New York is, 

 of course, not at all surprising when one considers the large 

 number of southern forms with a similar range.

Kraemer's Text=book of Botany and' Pharmacognosy* 



This book is intended for the use of students of pharmacy, as 

 a handbook for food and drug analysis and as a work of refer- 

 ence. It appears as a second edition of a former work of Pro- 

 fessor Kraemer's, published in 1902, even though that had a 

 slightly different title, and the subject-matter has been so 

 changed and extended that it might well be issued as an inde- 

 pendent work. The first edition was a small octavo book of less 

 than 400 pages, with 17 plates inserted at the close of the text, 

 and with practically no discussion of botanical theory. The 

 present volume is a larger octavo of over 800 pages, with 321 

 figures dispersed through the text, and over one fourth of the 

 discussion is devoted to pure botany.
