views in reference to lichens were fully stated in a review of his Zexrt-do00k of 
general lichenology, published in the GAZETTE (25 : 284. 1898), and there is no 
need to repeat them here. On account of existing difficulties of nomen- 
clature, the author omits all citation of authorities, stating that “the names 
given are well authenticated, so that those who have the desire and the oppor- 
clature controversy.” A selection is made of the more common forms of 
lichens occurring in the United States, those with which the collector is most 
likely to come in contact. 
The first part of the book discusses lichens in general, under such head- 
ings as “The history of lichenology,” “The use of lichens,” “ What are 
lichens,” “The morphology and physiology of lichens,” “ The occurrence 
and distribution of lichens,” and “Lichens and the naturalist,” under which 
last title directions for collection, study, and preservation are given. 
The second part is devoted to the systematic presentation of the group, an 
artificial key being provided for the more important genera, and a natural 
key for the families. A check list of lichens occurring in the United States is 
also given, useful to those who wish to make exchanges or to get some knowl- 
edge of the extent of the group and its various genera.— J. M. C. 
MINOR NOTICES. 
A NEAT MANUAL of seventy-nine pages and half a hundred cuts has been 
recently issued by W. Edgar Taylor, professor of biology in the Louisiana 
Industrial Institute, for the use of his classes. The printing was done and 
many of the drawings were made by pupils of the school, and the result is 
creditable. It is intended solely to meet local needs, including lessened cost 
to the pupils, and, although in book form, is of the nature of extended labora- 
tory notes. It goes over the ground of the cryptogamous plants and uni- 
cellular animals, with an introduction on the cell.—J. C. A. 
Justenia, and Chalazocarpus) and fifty-eight new species being described. 
The only other new genus is Campylochiton (Combretacez).— J. M. 
A LITTLE BOOK before us by Clarence Moores Weed, entitled Seed travel- 
ders, has been prepared as a supplementary reader in connection with nature
