(Communicated in the meeting of June 29, 1918). 



I. Ill a previous publication ^) we iiave ostablislied that the 

 nebulae of salicjlic acid salts generated hy spraying, owe their 

 electrifying power to the contained anion. 



Kig. 1. hifluence of O.l n. NaCI and 6 "/i, canesugai- on the charge 

 of salicylas natricus.

1. Curve of the Charge of salicylas natricus alone. 



2. Curve of the Cliarge of salicylas natricus + salt. 



3. Curve of the Charge of salicylas natricus + sugar. 



Along the top-abscissa the normal concentrations, along the bottom abscissa 



the logarithms of the normal concentrations of salicylas Na. are given ; 



along the ordinate tlie deflections of tlie electroscope in scale-divisions.
