ANIMAL KLECTKRITV. LFXTURE VI. 12/ 



find it convenient to adopt some conventional ex- 

 pression for that ratio. The number expressing the 

 value of the magnitude of A. divided by the magnitude 

 of K. presents itself as a natural formula, and we shall 

 hereafter refer to it as the quotient ^/k- 



We are now able to say from examination of 

 records in which both A. and K. have been modified, 

 that the characteristic effect of acidification is a 

 diminution of the quotient ^/k, and the characteristic 

 effect of basification an augmentation of the quotient 



We are entitled further to make the statement 



that acidification affects first Anodic then Kathodic 



polarisation, causing first increased then decreased 

 effects, their order of appearance being : 



1. Increased A. as the first effect. 



f Diminished A. ) .u . • i /r . 



2. -, T T jr -as the typical enect. 

 ( Increased K. ) ^^ 



3. Diminished K. as the last effect. 



The first effect is frequently missed, even with 

 a weak acid, such as COo. The second effect is not 

 often obtained pure ; more frequently we find a large 

 diminution of A. together with a relatively smaller 

 diminution of K., i.e. an absolute diminution of the 

 quotient -^ k. 



These are dry statements ; it was, however, in- 

 cumbent upon me to make them, in order to lay open 

 the grounds upon which I have concluded that //ic
