Title
[MB225], Letter from Edison Machine Works, Henry E Walter to Charles Batchelor, May 16th, 1887
Editor's Notes
Three page handwritten letter discussing the 8 1/2, 9, and 10 test results on armature cores. Table I sent you includes all the data I have on the tests. It gives the temperature of the armature inside and out, and that of the room, and also the cooling value of the armature and the probable absolute heat generated calculated from this.
