ditions of sensation elements in non-psychical processes, so a 

 careful analysis of the facts of perception force us to look for the 

 represented factors and for the synthetic activities in non-psychical 

 conditions. In support of this position examples were cited in 

 which the representative factors were not capable of conscious re- 

 vival even with concentrated attention, and it was shown that syn- 

 thetic activities become progressively less conscious the more 

 complete and immediate the process of perception becomes. 

 'Finally, the attempt was made to discover in the facts of move- 

 ment and in the nervous processes which follow the reception 

 of sensory stimulations, the conditions of perceptual synthesis 

 and the conditions which make possible the present effects of past 

 experience without complete or even partial revival of any sen- 

 sory factors, either as revived sensations or as repeated sensoiy 

 stimulations in the nervous system.

PUBLIC LECTURE. 



October 30, 1899. 



Under the Auspices of the Section of Anthropology and 



Psychology. 



Professor Hugo Munsterberg of Harvard University lectured 

 to a large audience on The Psychical and Physical World. 



The Professor pointed out that the science of Psychology 

 must seek to discover the factors of mental phenomena which 

 are more elementar}' than sensations. These factors are the 

 psychical atoms. Some of their attributes may be inferred from 

 the similarities which exist among sensations and from the 

 fusions which take place between sensations. Such atoms are 

 not forms of reality, but logical concepts made necessaiy by the 

 demands of explanatory science.
