with Freundlich's law of adsorption as I had erroneously supposed 
(these Proceedings, 1, p. 270; 2, p. 37). 
The distilled water used in my previous experiments was slightly 
acid and thus stimulating in slight dilution and depressant in stronger 
dilutions (see Table I, column 1) thus giving the semblance of an ad- 
sorption curve. Nor did I realize the effects of sHght changes in tem-

Lillie advocates an extension of the theory of Faraday and de la Rive, 
that the transmission of the excitation state from the immediate site of 
activity to the adjoining resting area is dependent on an electrical local 
action of the same essential nature as that which is responsible for the 
etching or corrosion of non-homogeneous metallic surfaces, such as iron
