Photogenic Drawings of Snow Crystals, as seen in January 1854. By James Glaisher, F.R.S. This collection includes between 20 and 30 varieties, and was the result of a morning's observation on January 1st, 1854, with a temperature of 22¦. The figures, though minute, and observed under a lens of very moderate power, exhibited a high degree of crystalline formation, and great harmony of arrangement. Temperature of air at 9 A.m. 23¦. Difference'of wet- and dry-bulb, 0o-5. Max. temp, during day, 31¦'5. Min. temp, during day, 21¦-2. Wind north. Photographic copies of the drawings made by Mr. Glaisher were presented to the meeting*.
* Mr. Glaisher has since continued his observations, in the winter of 1854-55, and has published many drawings of extremely varied forms in the ' Illustrated London News.' Drawings of Arctic snow crystals may be consulted in Scoresby's ' Voyages.'
[Snow crystals were sketched by James Glaisher and drawn properly by his wife Cecilia Louisa Glaisher. The drawings were then photographed for distribution and some of the photographs were sent in April 1857 to Herschel with permission to publish them "as he should wish".]
