comitance.’’ Of course thisis a wider field than 
mere joy as specific emotion, but inclusive of it. 
It may be surmised that the expansive move- 
ment for the pleasant and contrary for painful 
stimulus—which is reinforced by these experi- 
ments—is simplest biological reaction concerned 
with appropriation and rejection in feeding by 
primitive organisms. However, joy as specific 
emotion is later and must be studied more intro- 
spectively in its functional activity than Mr. 
Dearborn hasdone. In neurasthenia joy does 
not act, as I recall in my own case, once 
receiving news which normally would have 
brought great joy but left me quite listless at 
the time. 2

THE June number of the Botanical Gazette 
opens with a morphological study of the com- 
mon May apple, Podophyllum peltatum, by Mr. 
Theo. Holm, illustrated by ten figures drawn 
from nature by the author. Mr. Holm dis- 
cusses the mode of germination, the distribu- 
tion, relation and arrangement of the leaves 
and buds. Some structural details of the mature 
plant are also given. The study shows clearly 
that Podophyllum is closely related in its habits 
and ecological peculiarities to a little natural 
group of plants: Diphylleia, Jeffersonia, Caulo- 
phyllum, Acteea and Cimicifuga. He thinks it 
better to associate these plants than to separate 
them by the insignificant floral characters which 
have been used to put them into separate orders. 
Capt. John Donnell Smith continues his descrip- 
tion of new plants from Guatemala and other 
Central American republics. Mr. T. S. Bran- 
degee also describes a considerable number of 
new species of Western plants. Dr. C. O. 
Townsend discusses the effect of ether upon the 
germination of seeds andspores. He finds that 
a weak atmosphere of ether tends to hasten the 
time of germination, while a larger amount of 
ether retards or prevents it. Dr. A. P. Ander- 
son figures and describes a new Tilletia para- 
sitic upon the cultivated rice. Anappreciative 
biographical sketch of the late Dr. Alvin Went- 
worth Chapman is contributed by Dr. Charles 
Mohr, a long-time friend of Chapman. It is 
accompanied by a small but excellent portrait 
of Dr. Chapman. Professor F. A. Waugh dis- 
cusses the application of the name Prunus insi-
