TitleManuscript, 'On certain appearances of beams of light, seen as if emanating from candle or lamp flames' by James Thomson
Date1892
DescriptionWilliam Thomson introduces his late brother's paper: 'About the end of last January, when my brother was fully occupied in writing his paper on the Trade Winds for the Bakerian Lecture, he called my attention to the well-known beams or ladders of light seen below or above a lamp flame viewed with partially-closed eyelids, and he gave me verbally an explanation of the phenomenon which surprised me very much. By some simple and interesting trials with my own eyes, which he explained to me how to make, I was perfectly convinced that his explanation was correct; and believing it, as I still believe it, to be new, I urged him to write a short paper on the subject for the Royal Society, but not to let it interfere with his work for the Bakerian Lecture; and he undertook to do so as soon as might be after being freed from this work.'

Annotations in pencil and ink. Includes a diagram and corresponding sketch of the human eye.
