Title
[NM023123], Technical Note, Arthur Edwin Kennelly, May 22nd, 1889
Editor's Notes
Meter Test. Measurement of the Res. Of the new bottles. This test commenced on the 22nd May. 8 bottles were made up of this form shown on the opposite page [drawings on left page]. The density of solution was 1.110 and the solution was neutral. Five of these bottles were put in a warm box and three in the refrigerator The temperature record in F was as follows:-- [table folllows] The current strength was 5 x 10[-3] ampere so that the full deposit should be 5 x 15 x 1.135 x 10[3] x 1.224 = 0.695 grammes. The actual amount was observed to be 730 or 5% greater. Three of the bottles in the hot box and all three in the refrigerator were shunted. The current strength was found to have been excessive and the plates in the refrigerator were found to have smelted.[table follows on next page labeled: Measurement of Meter-Bottle = Resistance. Following this is a note undated, probably from end of May or beginning of June, on Rough Calculation of the variation of the Earths's Potential (do/dt) in time on the supposition that the sun is an electrified body.]
