[D8303ZCE], Letter from Thomas Corwin Mendenhall to Samuel Insull, April 15th, 1883
Editor's Notes
Would like some small cylinder of the hard carbon; ask about a plan of making the lamp with a ground joint so that the filament might be renewed. [SI2 replies: "ground glass wrs all right but the precentage of cracked Lamp & Slow leaking is so great where {?} under that it doesn't compensate for the advantages" "Will try & do what can in getting carbon cylinder for you"
