Visitors to Venus:
Evans, Ways of the Planets, p. 140:
That, in 1645, a body large enough to look like a satellite was seen near Venus. Four times in the first half of the 18th century, a similar observation was reported. The last report occurred in 1767.
A large body has been seen—seven times, according to Science Gossip, 1886-178—near Venus. At least one astronomer, Houzeau, accepted these observations and named the—world, planet, super-construction—"Neith." His views are mentioned "in passing, but without endorsement," in the Trans. N.Y. Acad., 5-249.
Astrophysical Journal, 1-127:
A light-reflecting body, or a bright spot near Mars: seen Nov. 25, 1894, by Prof. Pickering and others, at the Lowell Observatory, above an unilluminated part of Mars—self-luminous, it would seem—thought to have been a cloud—but estimated to have been about twenty miles away from the planet.
Luminous spot seen moving across the disk of Mercury, in 1799, by Harding and Schroeter. (Monthly Notices of the R.A.S., 38-338.)
In the first Bulletin issued by the Lowell Observatory, in 1903, Prof. Lowell describes a body that was seen on the terminator of Mars, May 20, 1903. On May 27, it was "suspected." If still there, it had moved, we are told, about 300 miles—"probably a dust cloud."
In 1859, Dr. Lescarbault, an amateur astronomer, of Orgères, France, announced that, upon March 26, of that year, he had seen a body of planetary size cross the sun.
We are told that Leverrier "satisfied himself as to the substantial accuracy of the reported observation." The story of this investigation is told in Monthly Notices, 20-98
According to the Annual Register, 9-120, upon the 9th of August, 1762, M. de Rostan, of Basle, France, was taking altitudes of the sun, at Lausanne. He saw a vast, spindle-shaped body, about three of the sun's digits in breadth and nine in length, advancing slowly across the disk of the sun, or "at no more than half the velocity with which the ordinary solar spots move." It did not disappear until the 7th of September, when it reached the sun's limb.
M. Croste, at Sole, about forty-five German leagues northward from Lausanne, had seen it, describing the same spindle-form, but disagreeing a little as to breadth. Then comes the important point: that he and M. de Rostan did not see it upon the same part of the sun. This, then, is parallax, and, compounded with invisibility at Paris, is great parallax—or that, in the course of a month, in the summer of 1762, a large, opaque, spindle-shaped body traversed the disk of the sun, but at a great distance from the sun. The writer in the Register says: "In a word, we know of nothing to have recourse to, in the heavens, by which to explain this phenomenon."
That another amateur astronomer, M. Coumbray, of Constantinople, had written to Leverrier, that, upon the 8th of March, 1865, he had seen a black point, sharply outlined, traverse the disk of the sun. It detached itself from a group of sun spots near the limb of the sun, and took 48 minutes to reach the other limb. Figuring upon the diagram sent by M. Coumbray, a central passage would have taken a little more than an hour.
Haase had collected reports of twenty observations like Lescarbault's. The list was published in 1872, by Wolf. Also there are other instances like Gruthinsen's:
Amer. Jour. Sci., 2-28-446:
Report by Pastorff that he had seen twice in 1836, and once in 1837, two round spots of unequal size moving across the sun, changing position relatively to each other, and taking a different course, if not orbit, each time: that, in 1834, he had seen similar bodies pass six times across the disk of the sun, looking very much like Mercury in his transits.
In the London Times, Jan. 10, 1860, is Benjamin Scott's account of his observation:
That, in the summer of 1847, he had seen a body that had seemed to be the size of Venus, crossing the sun. He says that, hardly believing the evidence of his sense of sight, he had looked for someone, whose hopes or ambitions would not make him so subject to illusion. He had told his little son, aged five years, to look through the telescope. The child had exclaimed that he had seen "a little balloon" crossing the sun. Scott says that he had not had sufficient self-reliance to make public announcement of his remarkable observation at the time, but that, in the evening of the same day, he had told Dr. Dick, F.R.A.S., who had cited other instances. In the Times, Jan. 12, 1860, is published a letter from Richard Abbott, F.R.A.S.: that he remembered Mr. Scott's letter to him upon this observation, at the time of the occurrence.
Or the total eclipse of July 29, 1878, and the reports by Prof. Watson, from Rawlins, Wyoming, and by Prof. Swift, from Denver, Colorado: that they had seen two shining objects at a considerable distance from the sun.

Prof. Watson and Prof. Swift published their observations.
In the Observatory, 2-161, Swift says that his observations and Watson's were "confirmatory of each other."
In 1783 and 1787, Herschel reported more lights on or near the moon, which he supposed were volcanic.
