[D8835ACF], Letter from Samuel Insull to West Orange Laboratory, April 6th, 1888



"I return you herewith your two bills of March 29th. I do not understand the bill rendered against us prior to January 1st. The only experiments that we know of, which Mr. Edison was conducting at our expense, was experiemnts on a new dynamo and experiments on insulation. The arrangement made with him as to these were after January 1st., and not prior to January 1st. On your statement you show five different experiemtns. I should like very much to have some further information with relation to your bill for the month of January. We ourselves, under Mr. Edison's instructions, have made a series of experiments, which we presume are analogous to the magnetic pendulum experiment, and if Mr. Edison had desired to continue this experiment, we could have sent him our appratus, as it is of no use to us. Our previous remarks with relation to the experiments on hand at the Laboratory for our account also belongs to this bill. We think it only right that we should have a full understanding as to what experiments are conducted for our account, what becomes of the material after the experiments are finished. You charge us with labor and material in connection with the experiments, and when the experiments are voer we certainly should be credited with such material, as I presume you seel it as scrap." "P.S. You must remember that we are running this business to show profit, that experimental exenses like other expenses have to come out of our profits--which are anyways very small now--& that it is our duty to keep our expenses as low as possible."
