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

Description

William Huggins writes: 'I have added the name of Mrs Huggins to the title of the paper, because she has not only assisted generally in the work, but has repeated independently the delicate observations made by eye. In the year 1882 I had the honour to lay before the Royal Society a note on the photographic spectrum of this nebula [see PP/1/35], in which I described a new bright line in the ultra-violet, to which I gave a wave-length of about 3730. In addition to this new line, the lines of hydrogen, Hβ and Hγ, which I had discovered by eye in my early observations on the visible spectrum, were to be seen upon the plate.'

Annotations in pencil and ink throughout. Includes one page of diagrams of the spectrum of the Orion nebula.
