Hayne; Xyris Caroliniana, Walt.; Utricularia cornuta, Michx.; and 
Eriocaulon septangulare, Withering.  Pogonia ophioglossoides, Nutt., 
in fruit was also abundant and showed two late albino blossoms. 
Along the water's edge, but not immersed, numerous plants of .Se/e- 
rolepis verticillata were found, with flowers almost mature. A com- 
parison of the specimens collected in Bradford with those from 
southern localities reveals no important differences. The species 
as it occurs in its more southern habitat is somewhat variable in 
height, in width of leaf, and in the firmness of the stem, differences 
depending in part upon whether the individual plants are growing 
in, or near the water. The Bradford specimens correspond to the 
shorter form, growing on the sand, and having a firm stem and 
numerous short leaves. Specimens collected at Bradford have 
been deposited in the Gray Herbarium of Harvard University. —

A Work FOR TEACHERS OF BroLoGY. —In “The Teaching of 
Biology”* Professor Lloyd and Dr. Bigelow have treated their 
theme with considerable fulness, great painstaking, and much 
advantage to teachers of biology. ‘The aims and scope of the 
book may be seen from the following partial list of chapter sub- 
jects: the value of biology in education; nature study; the value 
of botany in secondary education; various types of botanical 
courses ; principles to be emphasized; detailed discussion of the 
course; laboratory and materials; botanical literature; the value of 
zoology; animal nature study and human physiology in the elemen- 
tary school; the subject matter and the outline of a course for the 
secondary school; the relation of zoology in secondary school and 
in college. The full bibliographies and references to pedagogical 
literature are especially valuable. As regards the class of teachers 
to whom the work will prove to be of most service, it may be said 
that the general suggestions and the specific directions to teachers 
in secondary schools are of most value. The ideals of the authors
