[LM111357], Letter from Arthur Edwin Kennelly to William J Jenks, Edison Electric Light Co, March 13th, 1889

Editor's Notes

####[page 179]####13th March 1889####M W.J. Jenks####Director Standardizing Bureau####Dear Sir####I beg to acknowledge with many thanks your letter of yesterday's date. There is very little in the existing edition of the meter pamphlet to which I can find exception, but as you are kind enough to invoke suggestions I would mention the following page 12 paragraph 3 has already been pointed out to you I think as not being quite clear.####Page 16. (Placement of meters) Since the temps comp------ in apt -- considerably defective below 13 [degree symbol] F it might be -- to say that a meter operator better above that temps####page 23 paragraph 4 & 5. I think that in view of the results obtained in the past year that it would be well to advise the use of distilled water wherever it can be obtained, and ice water as second best only.####page 25. --- 4. I think as a mere detail that circular glass plates are more convenient than paper disk as --- covers being cleaner and less hygrometric.####page 29. Par. 0. Possibly it might be well to give the simple alternation (in the absence of potassium ind------ of dipping the two wires, carefully kept apart, in water, and that the wire which gives off gas is then negative. This is a very handy test as you know when test paper is not at hand.####[page 180]####page 31 at bottom and page 32 (radiation 2nd par) I do not know whether practice should go so far as to condemn the proceeding which results have shown to be attended with a certain loss of zinc. You will be able to judge.####Page 44 (Note) Mr Edison prepares#####Finally I think that I would add the figures for working out the meter constant given in your papers [rent?] before the Engineers. I certainly admire the absence of all complication formulae and figures that are not needed in the pamphlet, but for the uses of those who may desire to make themselves acquainted with further details I would give that information. Also I think I would give the resistance of the shunts in the various sizes of meter arranged in a tables. The meter need be ashamed of nothing.####Finally I would suggets a few concluding remarks emphasizing the statement made in the preface--to the effect that if the directions be followed out the meter is more accurate than any other in existence re. I think that the Edison meter will certainly justify all you can say for it.####Believe me to remain####Yours very truly####A.E. Kennelly####
