Title
[D8227ZAA1], Memorandum, Charles Lorenzo Clarke, June 30th, 1882
Editor's Notes
1st page is graph plotting 3 quantities: investment, lamps per hp, and "amount recd per M. S. 1.20"(?). "Explanation of diagram showing advantage commercially of high economy of lamps if the life can be maintained constant. It is a fact that with all other factors the same, any increase in the economy of lamps decreases their life, but the great end to be attained, with reasonable endurance of the life of the lamp, is to increase the economy, for besides the direct running expenses it diminishes the investment and depreciation for a plant with a given lamp capacity." xxx It's long, but maybe select; good view of engg economy; dh 17jan03 xxx
