| Title | Letter from William Huggins, 90 Upper Tulse Hill, S W [South West] London, to the Secretary [Joseph Larmor] |
| Creator | Huggins; Sir William (1824-1910); British astronomer |
| Recipient | Larmor; Sir Joseph (1857-1942); Irish theoretical physicist |
| Date | 21 July 1908 |
| Description | Huggins informs Larmor that [George Ellery] Hale 'has strong evidence of the existence of magnetic fields in sun-spots adequate to produce [Peter] Zeeman's effects. The Nichol has shown almost certainly that not only the double lines in spot spectra are true Zeeman doublets, but that also the widened lines are due to a magnetic field'. Hale will be writing to 'Nature'. Huggins questions the presence and strength of the magnetic fields. He reflects that 'an Iceland prism would be of no use', on account of loss of light, if only one ray were in use'. Hale is has prepared his reflector at the summit of Mt. Wilson, but it will scarcely be ready for work this summer. He dislikes [William] Ramsay's letter in 'Nature'. |
