A Green Sun


I RECOLLECT reading some years ago in NATURE an observation of Mr. Norman Lockyer, to the effect that he had seen the sun green through the steam escaping from the funnel of a boat on Lake Windermere. In May 1888, I spent a considerable time one day viewing the sun through steam escaping at various pressures from the boilers of a colliery in Monmouthshire. In no case could I, or the friends with me, succeed in seeing the sun of a green colour through the steam, although we viewed it in a very great variety of ways. All we saw was the usual orange or red coloration.
