 has been helping with the experiments on memory, is about to begin a 

 research on attention, and it is lioped that next year there will be 

 others ready to undertake original work. Among the subjects for wliich

 The l)nilding ofcomi)lex perceptions, exertion, and fatigue, tin* meas-

J)r. Joseph Jastrow bas prepared for the series of Fact and Theory 

 Papers a small volume on the time-relations of mental phenomena. "The 

 study of the time-relations of mental phenomena is imjxutant from 

 several points of view. It serves as an index of mental complexity, 

 giving the sanction of objective demonstration to the results of subjec- 

 tive observation ; it indicates a mode of analysis of the simpler mental 

 acts, as well as the relation of these laboratory products to the pro- 

 cesses of daily life; it demonstrates the close inter relation of psycho- 

 logical with physiological facts, an analysis of the former being indis- 

 pensable to the right comprehension of the latter; it suggests means 

 of lightening and shortening mental operations, and thus offers a mode of 

 improving educational methods ; and it promises in various directions to 

 deepen and widen our knowledge of those processes by the complication 

 and elaboration of which our mental life is so wonderfully built up. Au 

 excellent bibliography of well sele(;ted authorities relating to general psy- 

 cho-physics, time-reactions, adaptive reactions, and association times 

 will be found at the end of the volume. The Americaii Jonnud of 

 Faychology, edited by President Staidey Hall, and ))ublished at Clark 

 University, Worcester, Massachusetts, is the standard authority ou the 

 ])hysical side of psychology. 



Metai)hysical psychology, represented in the English i)ublicatiou 

 Mind, may be said to have fairly entered the arena of authropologj'

 both sides: Animal Intelligence, Alix, Foveau ; Double Conscious-
