[D8034ZDE], Letter from A W Weeks to Thomas Alva Edison, June 29th, 1880

Editor's Notes

Yours of 24th rcd. In your machine, do iron oxide & magnetite fall together or are they separated? Marg: "the ferrous or ferric oxides as well as the magnetite can be made to fall together or the magnetite may be separated from the oxide, but it is difficult to separate ferric from ferrous oxide. The machine requires 2 horses or a small motor of 2 horsepower."
