TitlePaper, 'On a re-determination of the principal line in the spectrum of the nebula in Orion, and on the character of the line' by William Huggins and [Margaret Lindsay] Huggins
Date1890
DescriptionThe authors write: 'I think it desirable to put on record the results of a re-determination of the position of the principal line in the spectrum of the nebula in Orion, under the more favourable conditions of a higher position of the nebula, and of some improvements in the instrumental arrangements. The spectroscopes have been furnished with new and sensibly perfect object-glasses by Sir Howard Grubb, and a new bright pointer has been fitted to the spectroscopes by Mr Hilger, which is illuminated by a small incandescent lamp, of which the brightness is controlled by suitable resistances. In all other respects the instrumental arrangements have remained unaltered.'

Annotations in pencil and ink. Includes one diagram of the telescope used by the authors and a printed proof of the paper.
