understands the painstaking work this represents. The detailed enu- 
meration of stations can not but be of vast help, not only to collectors, but 
in the study of geographical distribution as well. Professor Macoun has 
availed himself of all possible help from specialists, so that the catalogue 
contains the most recent changes in nomenclature. This part brings the 
genera to 737 and the species to 2950. 
THE LONG HOPED for continuation of Professor Tuckerman’s Synopsis 
cies being included in this part. Mr. Willey has done good service also 
in adding, in the form of an appendix, descriptions of N. Am. lichens not 
found in the Synopsis, but published by Professor Tuckerman in scat- : 
tered publications which are not easily obtained. 
“How to Stupy Botany” is the title of a very interesting paper by 
Dr. T. J. W. Burgess, of Hamilton, Ontario, read before the Hamilton 
Association. 
THE MEDICAL plants of the United States have attracted attention 
from Rafinesque down. The most recent contribution to this subject is 
by Dr. Carter, of Waukegan, Ill. The list is a very long one (over 300 
species), but only includes those plants whose medicinal properties are 
definitely known. The work has been carefully done, and forms a very 
compact reference book for information of that kind.
