The increase in the dissociation constant when the ionic concentration 

 is large is found to be represented quantitatively by the equation: 

 yV(I — y) . f = A: -)- c (I — y)/y- This empirical formula is applica- 

 ble to acids of all strengths. 



The decrease in the dissociation constant wlien the total concentration 

 is large is found to disappear under the assumption that ionization is 

 not spontaneous, but induced by the solvent. The legitimacy of this 

 assumption has lieen discussed, and the experimental data shown to be 

 in its support. The dissociating power of the solvent is ascribed to its 

 unsaturated character, i. e., to the presence of free valences. 



A discussion followed. 



The Section then adjourned. E. E. Smith, 



Secretary.

Summary of Papers 



Mr. Smith : 



Importance of Emotion. — Psychological study is beginning to confirm 

 common observation as to the significance of the feelings and emotions in 

 behavior. Educational practice has been in advance of educational the- 

 ory ; for it has sought to utilize feelings and emotions in development of 

 sane and efficient social workers. It has recognized that things that 

 affect or evoke emotional reaction and tend to ffet more immediate motor
