Where are the Nebulæ?

Abstract

MR. PROCTOR'S interesting paper in your last number reminded me of an essay on “The Nebular Hypothesis,” originally published in 1858, and re-published, along with others, in a volume in 1863 (“Essays: Scientific, Political, and Speculative.” Second Series), in which I had occasion to discuss the question he raises. In that essay I ventured to call in question the inference drawn from the revelations of Lord Rosse's telescope, that nebulæ are remote sidereal systems—an inference at that time generally accepted in the scientific world. On referring back to this essay, I find that, besides sundry of the reasons enumerated by Mr. Proctor for rejecting this inference, I have pointed out one which he has omitted.
