Title
[D8230ZCE], Letter from Francis Robbins Upton to Thomas Alva Edison, October 4th, 1882
Editor's Notes
"I have examined the principles of Mr [Boucher de Boucherville?] mercury pump. I think the pmup will work and that it embodies a new and patentable idea. That it will produce a vacuum cheaper than the present pump is to me, however, very doubtful."
