| Title | Unpublished paper, 'On the velocities of two distinct groups of secondary corpuscular rays produced by a homogeneous Röntgen radiation and their absorption coefficients in various gases' by Lewis Simons |
| Date | 1918 |
| Description | The object of the paper is to investigate the absorption coefficients of the secondary corpuscular rays in various cases and to find, if possible, a velocity distribution, from the maximum downwards, of the particles about the radiator.
Annotations in pencil and ink throughout.
