  value: I am instructed by Mr Edison to submit to your notice the following report upon the experiments with the Edison Electrolytic Meter conducted at his laboratory in Orange N.J. and in accordance with your wishes expressed in your letter to him of the 20th August last.##This report is divided into three principal sections as follows:--##1st The general discussion of the electircal working parts in the existing forms of meter and the degrees of accuracy under ordinary conditions obtainable together with the principal source of error##2nd The means can be adopted to eliminate or reduce these errors in the existing form of meter and under working conditions.##3rd The improvements in the existing form capable of being made in accordance with the results of the entire investigation.##Section 1.##General features##The accuracy of the Edison Electrolytic meter so far as its electrical operation is concerned depends upon the maintenance under all practical conditions of a fixed ratio between the resistance of the two branches of a divided circuit generally known as the shunt circuit, and - the bottle circuit: together with the restruction of the counter E.M.F. of polarization in the bottle circuit to certain due limits.##To determine practically how closely the indications of the meter were to be depended upon, under ordinary conditions, a series of experimental trials was made on various leads. The complete description and detail of their trials is given in Appendix A.##The conclusions afforded by these trials -- :--##1st That when meters are worked steadily at above 50% of this full lead, their indications are generally reliable to 2 o 3%.##2nd That when meters are worked at above 5% of their full lead but with marked intermission or period of rest they tend to underindicate.##3rd That this tendency to underindicate [inacases?] as the load on ht emeter diminishes. In actual trial error of as much as 15% have been met with at 20% & full load and under very unfavorable conditio…
