[CE87050], Letter from Alfred Ord Tate to Drexel Morgan & Co, December 30th, 1887



Re: your letter of 5th with communication from Co. Continentale. Discussed it at length wtih TAE. "From the information which Mr. Edison has given us, we are satisfied that iw doul really be impossible for him to prepare the data asked for by the Co. Continentale, for the reason that the improvements referred to have resulted simply from a careful revision of the various Departments through which the lamp passes on its way to completion, with the object of brigning each of the details of consrtruction as near to perfection as practicable. We find that special attention has been paid to the testing department, and all spotted or otherwise defective lamps eliminated, so as to avoid in a lot of, say, 10,000 lamps, the presence of two or three hunred inferior ones, which would reduce materially the average life of th ewhole. There is no one improvement which could be pointed to as the outcome of any patentable discovery. Mr. Edison is still engaged in an effort to effect further improvement..... We understand that the German Edison Co. has greatly improved its lamps though just such a course of attention to details as we have outlined, and we would suggest that the Co. Continentale adopt the same mehod....We have been informed that they have recently availed themselves of hte Agency of the Edison Lamp Co., at Antwerp, to which lamps from this country are sent for distribution in certain portions of Europe, and this will enable a comparison with the product of their own factory....."
