Title
[MBLB4480], Letter from Charles Batchelor to Francis Robbins Upton, March 16th, 1883
Editor's Notes
#456. Yours of 2/22 enclosing 3 duration curves rcd. But I don't understand the curves---seem to give conflicting information. Also, they're for 8, 6, 17 cp lamps; I use 8, 6, 13.5cp--when did you change back, and why? Are they for central station or other use?
