Title

[LB031328], Letter from Thomas Alva Edison to Lewis Miller, July 18th, 1889

Editor's Notes

"Referring to your favor of the 9th instant, there must be something wrong in the analysis you sent me, as the total doesn't foot up 100%. The original ore had about 20% iron in it. We simply raised the concentrate to 41.5 by tumbling. It probably could be got up to 45%, which is equivalent to a 55% magnetic ore." Yours truly, [signed] TAE
