motor problems now prominent in psy- 

 chology. 



"While experimental psychology has been 

 successful in extending its work from sen- 

 sation to movement, it has found great dif- 

 ficulty in devising suitable experiments on 

 the feelings. We may, therefore, welcome 

 a paper by Prof. Joseph Jastrow, which will 

 appear in the January number of the Pop- 

 ular Science Monthly, entitled ' The Popular 

 .i3Esthetics of Color.' At the Columbian 

 Exposition Prof. Jastrow arranged a psy- 

 chological laboratory and many visitors 

 were tested. The results have not yet 

 been published, but the preferences of 4,500 

 people for color were separately determined, 

 and these have now been collated with in- 

 teresting results. J. McK. C.
