1. Earlier predicted returns of comets (which were not fulfilled) made by Cassini and Bernoulli do not seem to have attracted any public attention.
2. The most detailed recent studies of this return are Taton René, “Clairaut et le retour de la comète de Halley”, pp. 253–74 in Arithmos-Arrythmos: Skizzen aus der Wissenschaftsgeschichte; Festschrift für Joachim Otto Fleckenstein zum 65. Geburtstag, ed. by Figala Karin and Berninger Ernst H. (Munich, 1979); Wallis Ruth, “The glory of gravity — Halley's comet 1759”, Annals of science, xli (1984), 279–86; and Broughton Peter, “The first predicted return of Comet Halley”, Journal for the history of astronomy, xvi (1985), 123–33. Wallis's paper is the only one of these to deal specifically with the public reaction to the comet's return. Based primarily on a selection of articles (mostly appearing after the actual reappearance of the comet) in the Gentleman's magazine and Benjamin Martin's General magazine, her paper deals almost exclusively with the interest in vindicating gravitational theory.
3. A more general study of “comet lore” in the seventeenth and eighteenth centuries is now being undertaken by Sara Schechner Genuth in her Harvard doctoral dissertation.

8. The alleged periods of the latter two comets were first suggested by Halley in the various 1705 printings of his “Synopsis”, e.g., A synopsis of the astronomy of comets (London, 1705), 22. The proposed 575-year period for the comet of 1680 was first attributed to Halley by Newton in the second edition (1713) of the Principia. Halley himself first publicly discussed this period in the expanded version of the “Synopsis” that was written sometime before 1717 and published in his posthumous Astronomical tables (Latin, 1749; English, 1752; French, 1759).
9. These figures were calculated by Newton and mentioned in the Example following Proposition XLI, Book III of the Principia; in the familiar Motte-Cajori translation (Berkeley and Los Angeles, 1934; hereafter: Motte-Cajori ed.), 521.

Whiston William, Astronomical principles of religion, natural and reveal'd (London, 1717), 155–6: “I observe, that the Sacred Accounts of Hell, or of the Place and State of Punishment for wicked Men after the general Resurrection, is agreeable not only to the Remains of ancient profane Tradition, but to the true System of the World also. This sad state is in Scripture describ'd as a State of Darkness, of blackness of Darkness, of Torment and Punishment for Ages, or for Ages of Ages, by Flame, or by Fire, or by Fire and Brimstone, with Weeping and Gnashing of Teeth; where the Smoak of the Ungodly's Torment ascends up for ever and ever; where they are Tormented in the Presence of the Holy Angels, and in the Presence of the Lamb; when the Holy Angels shall have separated the Wicked from among the Just, and have cast them into a Furnace of Fire. Now this Description does in every Circumstance, so exactly agree with the Nature of a Comet, ascending from the Hot Regions near the Sun, and going into the Cold Regions beyond Saturn, with its long smoaking Tail arising up from it, through its several Ages or Periods of revolving, and this in the Sight of all the Inhabitants of our Air, and of the rest of the System; that I cannot but think the Surface or Atmosphere of such a Comet to be that Place of Torment so terribly described in Scripture, into which the Devil and his Angels, with wicked Men their Companions, when delivered out of their Prison in the Heart of the Earth, shall be cast for their utter Perdition or second Death; which will be indeed a terrible but a most useful Spectacle to the rest of God's rational Creatures; and will admonish them above all Things to preserve their Innocence and Obedience; and to fear him who is thus able to destroy both Soul and Body in Hell.” I am grateful to Michael Hoskin for this reference.

Wesley may have been referring to the expanded passage (quoted below; see the text attached to ref. 76) on the close approach of the comet of 1680 with the Earth that Halley inserted in the revised version of the “Synopsis” that appeared in his Astronomical tables. As will be described below, it was Whiston who predicted a collision of this comet with the Earth at its next return.

A note (p. 125) that follows these papers says that Halley refrained from publishing them in 1694, “he being sensible that he might have adventured ultra crepidam; and apprehensive least by some unguarded Expression he might incur the Censure of the Sacred Order”.

See also ref. 67. In a collection of calculations of the transit of Mercury by an assortment of observers that appears in GM, xxiii (issue for May 1753), 211–12, the reporter “Candidus” says that he observed the transit with John Bevis (see ref. 68). In his account of the observations that appears in the Philosophical transactions, xlviii (1753), 192–200, James Short says that he observed at the house of Thomas Birch along with Bevis. I am grateful for these references to Ruth Wallis, who thus identifies “Candidus” as either Bevis, Birch, or Short, in descending order of probability.

Containing a brief description of the true system of the world, and an enumeration of all the discoveries which have been yet made concerning those temporary appearances, with respect to their orbits, forms, velocity, magnitudes, distances, tails, &c. particularly that whose return is expected in this or the following year, extracted from the writings of Sir Isaac Newton and other astronomers. To which is added, the opinion of that illustrious author, concerning the use of comets, the origin of matter, and his definition of the supreme being of the universe (London, 1757). Cowley's pamphlet was favourably reviewed in MR, xvii (issue for August 1757), 178–9. For biographical information on Cowley (1719 elected frs, 1768), who later taught (1761–73) at the Royal Military Academy at Woolwich, see Taylor, Mathematical practitioners (ref. 37), 226.
57. He was of course contrasting his pamphlet with Halley's Astronomical tables (Latin, 1749; English, 1752), in which the expanded and revised version of the “Synopsis” was to be found. It might be worth noting here that J. Richardson, the successor to W. Innys, the publisher of the tables, advertised the English version of the tables in LC, i, no. 68 (4 to 7 June 1757), 544, col. 3, and no. 74 (18 to 21 June 1757), 592, col. 3, as “This day is publish'd”, but this most likely was a new printing or remainders from Innys' stock.

The book received a favourable review in MR, xvii (issue for August 1757), 177–8.

62. LC, ii, no. 102 (23 to 25 August 1757), 190, col. 3. This newspaper dispatch was dated “Newcastle, August 20”. It perhaps may be worthwhile to quote here the extract regarding the phenomenon from one of the navigator's journals: “That, at Midnight, on Friday the 3rd of June last, in 77 Deg. 30 Min North Latitude, the Weather being clear, they observed the Sun to be very bright, and encompassed with a luminous Circle, coloured like the Rainbow, at the Distance of 10 Degrees from his Body. After this they had dark close Weather; and, at Four in the Morning, the Appearance of a bright Sun broke out to the Eastward, about 60 Deg. above the Horizon, accompanied with a broken Halo or Semicircle, distant from it 11 Deg. the Back of which was turned towards the true Sun, and from this Halo issued a Tail or Stream of Light, extending 50 Degrees in Length towards the North.” The author of the newspaper dispatch remarked that this phenomenon resembled one that had been seen at Rome on 20 March 1629 and which Descartes had circumstantially described in the tenth chapter of his “Book of Meteors”, i.e., the final portion of his Discours de la méthode … (Leiden, 1637).
63. Bradley J., “Observations upon the comet that appeared in the months of September and October 1757, made at the Royal Observatory”, Philosophical transactions, I (1757), 408–15. The first sighting of the comet was made by Christian Gärtner near Dresden on 11 September, according to Klinkenberg Dirk, “Observations on the late comet in September and October 1757; made at the Hague”, “That, at Midnight, on Friday the 3rd of June last, in 77 Deg. 30 Min North Latitude, the Weather being clear, they observed the Sun to be very bright, and encompassed with a luminous Circle, coloured like the Rainbow, at the Distance of 10 Degrees from his Body. After this they had dark close Weather; and, at Four in the Morning, the Appearance of a bright Sun broke out to the Eastward, about 60 Deg. above the Horizon, accompanied with a broken Halo or Semicircle, distant from it 11 Deg. the Back of which was turned towards the true Sun, and from this Halo issued a Tail or Stream of Light, extending 50 Degrees in Length towards the North.” 483–8. For other European observations of this comet, see Pingré A.-G., “Mémoire sur la comète qui a paru en cette année 1757”, Mémoires de l'Académie Royale des Sciences [Paris], 1757 (publ. 1762), 97–107, and those cited in refs 64–66 and 68 below. On the western side of the Atlantic Ocean, apparently only Thomas Stevenson and others in Barbados observed this comet. A brief dispatch concerning this sighting appeared in The Boston-gazette, and country journal, no. 139 (28 November 1757), p. [2], col. 3.

65. LC, 2, no. 118 (29 September to 1 October 1757), 313, col. 1. An identical report was published at the end of October in LM, xxvi (issue for October 1757), 514.

The first letter, dated 27 September, was written by “Astrophilus Londinensis”; the second, dated 29 September, by “B.J.” (John Bevis). The latter letter also appeared in GLM, xxvi (issue for September 1757), 443. Extracts from both letters appeared in SM, xix (issue for September 1757), 489–90.

Martin's lecture rivals also took advantage of the current popularity of comets. James Ferguson also advertised in the 10 October DA (p. [2], col. 3) to announce that he would that night begin a course of astronomical lectures; in the first lecture, on the solar system, he promised that “the Motions of the Comet [will be] shewn by a particular Machine”. Two weeks later, Richard Oliver, a mathematics teacher at Greenwich, announced a lecture, to be given on 27 October, on comets, in which “the Nature and Uses of these stupendous Bodies will be shewn, also the Observations necessary to trace their Orbits exemplified, and the Methods of delineating their Paths on a Celestial Globe. The whole illustrated by the Comet which now appears, and that which is soon expected to return into our System” (DA, no. 8357 (24 October 1757), p. [2], col. 3).

79. Season also recalled that comets were thought to be “certain Presages of the Death of Emperors, Kings, or Men in eminent Stations, and of Destruction to ancient Powers”. He was joined in this belief by “Francis Moore”, who thought “there is Reason for postponing the Downfall of France till 1759, and for looking upon the Comet, which is to appear this present Year 1758, as the fore-runner of this important Event” (Vox stellarum: Or, a loyal almanack for the year of human redemption, 1758 (London, n.d.), 11).

The article title given here is from LsEP; GM had the page heads “Comets not dangerous” and “Desiderata in astronomy”, while the NGM printing carried neither a title nor a page head. Ruth Wallis identifies the author as Thomas Fisher, gent., Cold Bath Square, who is mentioned in GM, xx (1750), 446; xxi 1751–177; and 28 (1758), 367–8.
85. Quoted from a second letter from Fisher (see ref. 104).

87. LsEP, iii, no. 162 (31 July to 2 August 1758), 109. In the passages from this essay that I quote below, I have retained the original small caps and italics, but 1 have divided the essay into several paragraphs for clarity.
88. On Martin's failed attempts to become a Fellow of the Royal Society, see Millburn John, “Benjamin Martin and the Royal Society”, Notes and records of the Royal Society of London, 28 (1973), 15–23.
89. A reference to Martin's lecture of 23 December (see ref. 77); Fisher (see ref. 104) refers explicitly to this lecture. The authors may have attended this particular lecture.
90. In an earlier dispute with Martin over electricity, John Freke, an eminent surgeon and Fellow of the Royal Society, criticized those who took money for electrical demonstrations, a practice Freke thought would inevitably encourage the employment of any tricks that could more easily gain the applause of the audience, and characterized Martin as a mere “country showman”. Martin took great offence at these remarks and wrote a witty and devastating attack on Freke in A supplement containing remarks on a rhapsody of adventures of a modern knight-errant in philosophy (Bath, 1746). On this dispute, see Millburn, Martin (ref. 5), 54–58. The satirists, like G.T. and Henry Season earlier, apparently shared Freke's contempt for those individuals, such as Martin, who lectured or wrote for profit on natural philosophy.
91. An obvious reference to the broadside published by Martin in February 1757 (see ref. 41).
92. Apparently Fisher (see ref. 84).
93. Possibly a reference to John Bevis (see ref. 68).
94. In LsEP, ii, no. 91 (15 to 17 February 1758), 168, and LC, iii, no. 178 (16 to 18 February 1758), 166, there appeared a letter (dated 16 February) from “B. I.” entitled “Of the present remarkable bright appearance of the Planet Venus”. The author recalled that “The late eminent Dr. Halley has, in the Philosophical Transactions, observed, That it may be justly reckoned one of the principal uses of the Mathematical Sciences, that they are in many cases able to prevent or correct the superstition of the unskillful vulgar; and by shewing the genuine causes of rare appearances, to deliver them from the vain apprehensions they are apt to entertain of what they call Prodigies, which sometimes by the artifices of designing men (as of late with regard to the expected Comet) have been made use of to very ill purposes”. The author then briefly described Halley's determination that Venus would be brightest at about 40° elongation from the Sun, about halfway between its greatest elongation and inferior conjunction. After noting that the latter two events in early 1758 would occur on 14 January and 27 May, the author observed that the time for Venus's greatest apparent brightness was thus “just now”. In the semiannual index to their newspaper, the editors of the LC attributed this article, perhaps inadvertently, to “Dr Bevis”, although the identity of “B.I.” was probably well known to readers.
95. Martin, The theory of comets illustrated (ref. 59), 18–19. How Martin could square a c. September perihelion date with a possible 12 May descending-node passage is unclear. Perhaps he was unaware of the contradiction between his statements on the times of these separate but related events.

97. Martin, “The young gentleman and lady's philosophy” (see ref. 5), 107–13. The performance and use of such devices by Martin, Desaguliers, Demainbray, Ferguson and others has been studied by John Millburn and J. E. Nuttall in a paper currently being considered for publication.
98. Millburn, Martin (ref. 5), 108. For comments on Cuffs work, see Turner G. L'E., “Henry Baker, F.R.S., founder of the Bakerian Lecture”, Notes and records of the Royal Society of London, 29 (1974), 53–79.
99. For a description and illustration of them, see Millburn, Martin (ref. 5), 90, 92–95. Among his advertisements for them were “Visual Glasses, or Spectacles of a new Construction, agreeable to the Rules of Optics for assisting the Sight in the best Manner, and preserving the Eyes from the ill Effects they are liable to from common Spectacles” in LC, ii, no. 131 (29 October to 1 November 1757), 420, col. 3. Apparently inferior imitations were produced, causing Martin to warn in another advertisement that “Those that have not the initial Letters B.M. on the Frames, are not of Mr. Martin's Make, but pirated” (DA, no. 8477 (13 March 1758), p. [2], col. 3). This advertisement apparently did not go unnoticed, for soon, as Millburn notes, pedlars and hawkers were selling their cheap imitations with BM initials on the frames.
100. The relevant passage, as excerpted from Samuel Butler, Hudibras, with Dr. Grey's annotations, ii (London, 1819), 199–203, is as follows: It happen'd as a boy, one night, Did fly his tarsel of a kite; The strangest long-wing'd hawk that flies, … His train was six yards long, milk white, At th' end of which, there hung a light, Inclosed in lanthorn made of paper, That far off like a star did appear. This Sidrophel by chance espy'd, And with amazement staring wide, Bless us! (quoth he,) what dreadful wonder Is that, appears in heaven yonder? A comet, and without a beard! Or star that ne'er before appear'd? … It must be supernatural, Unless it be that cannon-ball, That shot i' th' air point-blank upright, Was borne to that prodigious height, That learn'd philosophers maintain, It ne'er came backwards down again; This passage has appeared more recently in DigbyJoan,(ed.), Permutations: Readings in science and literature (New York, 1985), 116–18. Martin himself had quoted two unrelated lines from Hudibras in the “Of the comets” section of “The young gentleman and lady's philosophy” (ref. 5), 104.
101. An announcement that “Mr. Dunn, a Teacher of the Mathematicks, has discovered a Method whereby several Maps of the Earth and Heavens of his constructing, answer all the uses of a large Pair of Globes”, appeared in DA, no. 8383 (23 November 1757), p. [1], col. 2, and LC, ii, no. 142 (24 to 26 November 1757), 506, col. 2. John Millburn has informed me that a testimonial — signed by six mathematics teachers, including John Cowley — for Samuel Dunn's planispheres appeared in the 7 January 1758 issue of Jackson's Oxford journal. In 1759, Dunn published both a Lecture on comets and The description & use of the universal planisphere; or, terrestrial & celestial globes in plane. With their applications … in geography, astronomy & navigation. For further biographical information on Dunn (1723–94), who was head of an academy in Chelsea at this time, see Taylor, Mathematical practitioners (ref. 37), 204–5.
