when the figure was rotated through 360 degrees and was 

 divided so that the illusion for each of the long lines was deter- 

 mined without reference to the next long line. It was found 

 that the illusion is not the result of equal deflections in opposite 

 directions of the neighboring lines. In some cases one of two 

 neighboring lines is not deflected at all, or even in a direction 

 opposite to that usually assumed. The important deflection is 

 in every second long line. Rotation through various angles 

 shows that there are four positions in which deflection is great, 

 four in which it is small. 



Professor Cattell described the methods he has employed to 

 select 1,000 American men of science for scientific study. 

 Among about 4,000 scientific men, there are about 200 psy- 

 chologists. The methods by which they w^ere arranged in the 

 order of merit were explained, and the possibility of measuring 

 degrees of scientific merit by the positions and probable errors 

 was discussed. Some statistics were then given in regard to 

 the academic origin, course and distribution of the psychologists. 

 They were educated at 'j6 different colleges, this large dispersal 

 indicating that in general psychologists are not greatly influ- 

 enced by the institutions at which they study. The members 

 who pursued graduate studies at different institutions were : 

 Berlin, Leipzig 35, Columbia 31, Clark 31, Harvard 30, Cor- 

 nell 25, Yale 16, Johns Hopkins 13. Of the 200 psycholo- 

 gists, all but eight are engaged in teaching or administrative 

 educational work, being distributed among JJ institutions. 

 Statistics were also given in regard to publications, from which 

 it appears that the United States contributes about one seventh 

 of the more important publications, leading in experimental psy- 

 chology. The paper will be published in the American Journal 

 of PsycJiology. 



Professor Dodge showed that photographic registration of 

 eye movements has exposed the poverty and inaccuracy of all 

 introspective data with respect to their number, velocity and 

 amplitude, while it shows that, even if our consciousness were 

 full and exact in all three aspects, it would be either useless or 

 misleading as a datum in the visual perception of motion.
