|Title||Paper, '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|
|Description||The 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.
