A December 1925 issue of Scientific Monthly featuring articles on telephone picture transmission, "Millikan rays," shadow bands from the total eclipse of January 24, 1925, biological engineering, the French race becoming extinct, and more. Millikan rays are cosmic electromagnetic radiation first captured by Nobel prize winner Robert Andrews Millikan. The eclipse article features some nice photos. This is a magazine packed with both ground-breaking real science and other work that did not pan out. About 6 1/2" x 9 1/2", 113 pages, softcover, well illustrated.

Good condition as shown with typical age tanning and edge wear. The binding is still intact and this is a good, solid, usable and readable copy.

A nice artifact of multi-disciplinary history and an awesome addition to any collection. I ship every day the post office is open with your item safely packed the way it deserves to be.
