[D8949AAT], Letter from John Birkinbine to Thomas Alva Edison, February 21st, 1889

Editor's Notes

I regret that I had so little opportunity to confer with you about my paper. I therefore spoke extemporaneously so as to take time to revise the matter with you for publication. I should very much like to spend several hours with you in this revision so that the paper when it goes to press will be truly valuable to you. There will be an edition fo about 1800 published for members, exchanges, etc. and in addition some 1400 will be printed to be bound in with the finished Volume of Transactions. As a member I have the prvilege of ordering as many author's copies as I choose at the cost of printing. It seems to me that by putting this paper in A. 1. shape it can be widely distributed to all the iron ore mines, blast furnaces, etc, and present concentration to them in such a light as will be advantageous.##Therefore think it very important that we take up the matter in detail together. If it will suit you I will come over some time next week. We should embrace a discussion of magnetism as it affects the action of your own and other separators.##I think it well also to sketch in a general way your investigations of various forms of separators to show that your present arrangement is the result of thorough study of the various methods proposed by others.##Everyone was delighted with the concentrator and the visit to the Laboratory in General. I think it now is the time to make the results generally known.
