| Title | Copy letter from Robert William Frederick Harrison to Prof P V Bevan, Royal Holloway College, Egham |
| Date | 24 January 1912 |
| Description | 'Paper on Spectra of Li and Cs.
Sir Joseph Larmor wishes me to enquire if you will be agreeable to the plate to above paper being reproduced by half-tone process, similarly to your plates with earlier papers. The only difficulty is that some of the fainter-white lines in the spectra may not show up. We believe however that it is not these but the dark lines which are the important ones - if you agree and will let me know the plate shall go forward at once.' |
