Paper, 'Note on the photographic spectrum of the great nebula in Orion' by William Huggins and [Margaret Lindsay] Huggins

Description

The authors write: 'From an examination of the photographs of the spectrum of the nebula in Orion taken by us in 1882, 1888, and 1889, we suggested in our paper “On the Spectrum, Visible and Photographic, of the Ore at Nebula in Orion,” “that the mottled and broken-up character of the nebular matter shown in Lord Rosse's drawings from eye-observations, and much more strikingly brought out in the recent photographs of Mr. Common and of Mr. Roberts, may be connected with differences of spectrum in the photographic region, though in the visible region there is no known alteration of the spectrum of the tour bright lines, except it may be some small differences of relative brilliancy of the lines. Until next winter we cannot go beyond the new information which these photographs give to us.'
