A proliﬁc observer, Hind also discovered two comets during this period: C/1846 O1 (de Vico-Hind) and C/1847 C1 (Hind). Included among notable works of his that concern us is The Comets: a Descriptive Treatise (1852), his work in tracing the apparitions of Halley’s Comet back to 11 BC, his careful analysis of ancient Chinese cometary records and his computations of the orbits of dozens of comets and asteroids. By the mid-nineteenth century asteroid discoveries were coming in so thick and fast that giving each one its own special planetary symbol was becoming extremely impractical.
On November 27 a magniﬁcent meteoric display took place, with its radiant in the constellation of Andromeda, on the very same day that Earth intersected the path of Biela’s Comet. If it was still out there, it would have been at that point in its orbit 2 months previously. Although the shower was by no means as spectacular as the Leonid storm of 1866, many who saw it were of the opinion that it was better than any other they had ever seen, Leonids excepted. Edward Lowe (1825–1900) at Highﬁeld Observatory near Nottingham, England, estimated that he had observed no fewer than 58,660 meteors between 17 h 50 min and 22 h 50 min.
S. government surveyor, observed the same storm from the deck of a ship off Cape Florida in the Gulf of Mexico. He recorded the event in his journal: About three o’clock am. I was called up to see the shooting of the stars (as it was commonly called). The phenomenon was grand and awful; the whole heavens appeared as if illuminated with sky rockets, which disappeared only by the light of the Sun after daybreak. The meteors, which at any one instant of time appeared as numerous as the stars, ﬂew in all possible directions, except from the earth, toward which they all inclined more or less; and some of them descended perpendicularly over the vessel we were in, so that I was in constant expectation of their falling upon us.
