Mr. C. Binks on Electricity, 



wards repeated with other acid mixtures of the strength 

 stated in the subjoined table. The copper plate being move- 

 able at pleasure, is fixed, first, at the nearest position to the 

 zinc, and afterwards in succession at each succeeding position 

 marked upon the horizontal line. All other particulars af- 

 fecting such experiments have already been sufficiently ad- 

 verted to throughout section 3rd, and the observances there 

 stated as necessary being fully discussed in that section, will 

 in no instance be restated or again referred to in the course 

 of the details that now follow. The amount of voltaic action 

 obtained at each position, is estimated by the length of time 

 in seconds required for the production of J^th of a cubic 

 inch of the hydrogen which is evolved from the copper plate.

 which the comparative amount of voltaic action is estimated 

 by the length of time in seconds required for the production 

 of one measure of gas.
