James Glaisher: James Glaisher (1809–1903) was the Superintendent of the Department of Meteorology and Magnetism at the Royal Observatory, Greenwich. Active in several scientific societies he pursued research on astronomy and meteorology and determined how the variation of the dew point with humidity.
copy … snow-crystals: Probably refers to Glaisher, ‘Snow Crystals in 1855’, Quarterly Journal of Microscopical Science, 3 (1855), pp. 179–85. This paper, which was illustrated with impressive drawings by Cecilia Louisa Glaisher (1828–92), was published in the journal’s July issue. Glaisher also delivered a paper ‘On the Severe Weather at the Beginning of the Year 1855: and on Snow and Snow-Crystals’ at the AGM of the British Meteorological Society on 22 May 1855. It was published later that year (or possibly even early 1856) in Report of the Council of the British Meteorological Society, read at the Fifth Annual General Meeting, May 22, 1855 (London: n.p., n.d), pp. 16–30. Tyndall referred to Cecilia’s illustrations of snow particles in his journal on 20 June 1855 (RI MS JT/2/13c/761).
