- Editor's Notes
- "Mr. Edison has been making some stests on the accuracy of our meters. I have followed the work and it has been very instructive. There are some questions not covered in his investigation which are of importance to us, and which should be gone into. I can bear witness personally to the hasty methods necessarily followed at the time the meter was adopted in its present form. ### In the present state of meter practice there are certain things we do not know, which it is important we should know. ### I will specify, ### Effect of Temperature, ### Effect of time, ### Effect of Oxidation, ### Effect of very large currents, ### Effect of very small currents, ### Effect of using the negative plate of this month for the positive plate of next. ### Mr. Kennelly has given me some information which he has obtained as to purity of materials, effect of acid in solution, compartive accuracy of pure and commercial zinc & c., which are of great value. ### We considering changes in the electrical constants of the meter, which if found practical willl largely decrease the expense of meter work. ### To decide intelligently we must know somethings exactly which we now know only generally or not at all. ### Mr. Edison having started the work and partly finished it at his own expense, and having facilities which could not have been obtained in former times-the present is a very favorable moment for our purpose." Respectfully, [unsigned]
