| Title | Paper, 'On the geometrical construction of the oxygen absorption lines great A, great B, and α of the solar spectrum' by George Higgs |
| Creator | Higgs; George (fl 1891-1893) |
| Date | 1893 |
| Description | Higgs writes: 'In the early part of August, 1890, the photographic work of the normal solar spectrum which I had undertaken had been carried as far as great A, or the limit of visibility in the red, and to λ 8350, or beyond z, in the invisible regions. During the two previous months of continuously dull weather, while classifying and comparing results, I was interested, on making a close examination of the head portion of the A line, to find the symmetrical construction, the rhythmical grouping, the harmonic order of sequence, and other characteristics of the B line repeated here in every detail.'
