TitleLetter from Francis H. Williams, 505 Beacon Street, Boston, to James Mackenzie Davidson
Date20th century
DescriptionTells Mackenzie Davidson of his enquiries into radium ores in America. Thinks that he has found a good ore for [Frederick] Soddy - one that will act on a photographic plate after an exposure of five days - and notes that he has made enquiries into the alleged presence of radium bearing ores in Colorado. Reminisces about the time they spent together in Mackenzie Davidson's dark room, and comments that he would be glad to hear more of the radium cases he showed him then.
