- Editor's Notes
- [sends tables of Lalande battery cells required for different CP battery lamps; also includes note for Kennelly (this should probably be indexed as Marshall to Kennelly) The drop in candle-power, given is that due to the drop in the cells and no allowance is made for the drop due to burning.####The calculations are made from the average --lls and amperes of the lamps that were sent us l####P.S.--Perhaps 9 cells would be better to use for the 3 c.p lamps but they will not give quite 3 C.P.
