| Description | Lyman is just back from Africa and as he sails tomorrow he will not be able to meet Larmor. He received an invitation from Mr. [Frederick] Purser in the [British Association] Dublin meeting and was sorry to put him to inconvenience. He found the sport so good in East Africa and the country so interesting that he prolonged his visit. He missed the Dublin meeting, saying that he has 'four lions, two rhino and lesser creatures'. He hopes to go on with the study of radiations from gases in the extreme ultraviolet, although the region shows peculiarities. He notes four sets of spectrum observations and the lack of spectral lines for some elements, writing 'what all this means I cannot guess'. He asks if Larmor is able to shed light on this. Lyman does not think it worth spending much time on 'this particular corner of the spectrum'. He has done the hydrogen spectrum as well as he can. He hopes to study the changes in excitation conditions and the effect on the nature of radiations of hydrogen, argon, and carbon. He asks for suggestions. |
