TitlePaper, 'Note on the photographic spectra of Uranus and Saturn' by William Huggins and [Margaret Lindsay] Huggins
DescriptionThe authors write: 'In 1871 I had the honour to communicate to the Royal Society an account of the examination of the visible spectrum of Uranus ['Note on the spectrum of Uranus and the spectrum of comet I., 1871', Proceedings of the Royal Society, volume 19]. The visible spectrum of this planet is remarkable, as it is seen to be crossed by several strong lines of absorption. Six of these dark bands are shown in a diagram which accompanies the paper, and their approximate positions in the spectrum are given. The spaces between the dark bands appear bright by contrast, and might suggest at first sight bright bands. I was unable to use a slit sufficiently narrow to enable me to determine whether the bright parts of the spectrum contain the Fraunhofer lines, which would be the case if Uranus, like the other planets, shines by reflected solar light.'
