SCIENCE. 



[N. S. Vol,. XVIII. No. 451. 



The educational applications of the subject 

 have found their chief outlet in The Edu- 

 cational Review (founded in 1891) and 

 The Pedagogical Seminary (founded in 

 1891), in which numerous special and gen- 

 eral articles have appeared from time to 

 time. For the present survey I deem it 

 hardly necessary to detail the avenues of 

 publication of psychological material to be 

 found in the medical, physiological and 

 biological periodicals. The work done in 

 abnormal psychology is also omitted in this 

 review. 



In lieu of having prepared a definite 

 statistical statement of fact respecting the 

 scope of the mass of literature thus vari- 

 ously appearing and which is steadily 

 growing, and thereby being able to specify 

 the exact items in psychology which have 

 been the successive objects of a possibly 

 shifting interest, I offer a sketch of these 

 considerations made by naming the first 

 and the last original articles appearing in 

 each volume of the two technical period- 

 icals published in this country. This 

 method of marking off the years has the 

 added benefit of the counter-checking due 

 to the multiple editorial selection of the 

 important and the less important material 

 available, which is apt to maintain a fairly 

 reliable average of values. The titles are 

 given in the following order : The first and 

 the last titles of a volume of the American 

 Journal of Psychology, with its years, are 

 first stated; then the respective titles of a 

 volume of the Psychological Review, with 

 its year — omitting in the latter instance 

 the presidential addresses before our asso- 

 ciation when they chance to be the leading 

 article, in which case the second article is 

 taken.

Generalization upon these captions is 

 impossible, and scarcely pertinent. These 

 thirty-six themes show a variation in in- 

 terest rather than a steady development 

 from a lower, narrower to a higher, broader
