| Description | Refers to his previous letter of a year ago, where he asked Mackenzie Davidson of his success with Radium in the treatment of skin diseases, and to which Mackenzie Davidson kindly provided a reply. Notes that a number of members of the Royal Astronomical Society are deeply interested in Mackenzie Davidson's work, and have been enquiring whether the effects of this treatment are permanent. Also asks, with regards to the emanations, what strength is best to use. Finally, asks whether Mackenzie Davidson has published the results of the cases he referred to a year ago and, if so, he could provide the names of these publications. |
