Abstract

"In reference to your telegram of yesterday, re insulating compound, we sent you on Nov. 21st last 30 lbs. of material (No. 326) that was meant to be melted and soaked into the cotton covering of the wire. ### In your letter of 12th instant you stated that the above material was all right, except that it would not liquefy sufficiently to penetrate the cotton thread. Before receiving your letter of 12th inst. We sent you 55 lbs of a material similar to No. 326. ### On Nov. 28th we sent you 160 lbs of a material which contained rubber. This latter was not supposed to be melted, but was intended to be masticated and squirted on wire. Your telegram of yesterday evidently referred to this. If it is worthless, you have been somewhat tardy in notifying us of the fact. ### We not have a compound that melts to perfect fluidity and will send you some of it in the course of a week." Very truly yours, [signed] TAE
