| Title | Paper, 'On the reversal of the metallic lines as seen in overexposed photographs of spectra' by W N [Walter Noel] Hartley |
| Date | 1882 |
| Description | Hartley writes: 'In preparing series of photographs of metallic elements when their spectra are obtained by the action of a condensed spark passed between metallic electrodes, I have been very careful to ascertain the exact period of exposure of the sensitive plate to the rays, which will bring out the most characteristic lines without the additional diffused rays of the air-spectrum; at the same time very delicate and feeble air-lines are adequately shown.'
