But it is within the knowledge of many persons in the midst of whom these memoirs are penned, that even the Juliana Library Company, in Lancaster (an inland and secondary town of Pennsylvania) experienced repeated proofs of the munificence of Mr. Penn, and also of his late truly noble and excellent consort, after whom that institution was named. The writer himself, well knows, from the tenor of numerous letters, not only from Mr. but Lady Juliana Penn, (who honoured the Rev. Mr. Barton with their friendship and correspondence, for the space of twenty years,—a patronage which was continued to a member of his family, long after Mr. Penn’s death,) the generous and unremitted attention of both, to whatever seemed likely to promote the honour or the interest of Pennsylvania.
Thomas Penn, Esq. died on the 21st of March, 1775, when he had just completed the seventy-fourth year of his age. He was the survivor of all the children of the illustrious founder of Pennsylvania; “whose virtues, as well as abilities, he inherited in an eminent degree,”—as was justly observed in an obituary notice published soon after his decease. Lady Juliana, his widow, survived him many years.
In the Pennsylvania Gazette (then published by Messrs. Hall and Sellers, but originally by Franklin and Hall,) for May 17, 1775, appeared the following just tribute to the memory of Mr. Penn.
“He had the principal direction of the affairs of this government for half a century, and saw such an increase of population, arts, and improvements in it, as during the like period, perhaps no man, before him, ever beheld in a country of his own. He rejoiced at the sight, was a kind landlord, and gave a liberal, often a magnificent encouragement, to our various public institutions. The Hospital, the College, our different Libraries and Religious Societies, can witness the truth of this: For he did not confine himself to sect or party; but, as became his station, and the genius of his father’s benevolent policy, he professed himself a friend to universal liberty, and extended his bounty to all. In short, as the grave, which generally stops the tongue of flattery, should open the mouth of Justice, we may be permitted to conclude his character by saying,—that he was both a great and a good man.”
The writer of these Memoirs hopes he will not be censured by any Pennsylvanian of generous feelings, for introducing, in the Appendix, some elegiac verses (by an unknown hand,) in commemoration of the virtues of this worthy man; who was not only a munificent benefactor to this country, and a bountiful patron of the Memorialist himself, as well as his family; but who, also, took a very friendly interest in the reputation and prosperity of Mr. Rittenhouse. These verses were published in The Pennsylvania Magazine, for Oct. 1775.
[125]. In addition to the honourable testimony of the Astronomer-Royal, in favour of the Pennsylvania Observers of the Transit of Venus, is the following eulogy of another eminent English astronomer,—as communicated by Dr. Franklin to Dr. T. Bond, one of the Vice-Presidents of the Philosophical Society, in a letter from London dated the 5th of Feb. 1772. The Rev. Mr. Ludlam, the gentleman referred to, and whom Dr. Franklin styles “a most learned man and ingenious mechanic”—in a paper published in the Gentleman’s Magazine (and a copy of which, subscribed by himself, was sent by him to the Society,) giving an account of the Society’s Transactions, more especially their Observations of the Transit of Venus,—applauds both the General Assembly and the late Proprietaries of Pennsylvania, for the countenance and assistance they gave to the making those Observations.——“No astronomers,” said Mr. Ludlam, “could better deserve all possible encouragement; whether we consider their care and diligence in making the Observations, their fidelity in relating what was done, or the clearness and accuracy of their reasonings on this curious and difficult subject.” He then mentions, in very honourable terms, the papers of Mr. Rittenhouse, Dr. Smith, Dr. Ewing, and Mr. Biddle, who drew up the several accounts of the Observations made at Norriton, Philadelphia, and Cape-Henlopen; and adds, that “they have very honestly given not only the Result of their Observations, but the Materials also, that others may examine and judge for themselves; an example worthy of imitation by those European astronomers, who are so very shy of giving particulars, and vouch for their Instruments and Observations in general terms.”
The same gentleman, in a letter dated at Leicester (in England,) January the 25th, 1772, and transmitted to the Philosophical Society by Dr. Franklin, wrote thus:—“The more I read the Transactions of your Society, the more I honour and esteem the members of it. There is not another Society in the world, that can boast of a member such as Mr. Rittenhouse: theorist enough to encounter the problems of determining (from a few Observations) the Orbit of a Comit; and also mechanic enough to make, with his own hands, an Equal-Altitude Instrument, a Transit-Telescope, and a Time-piece. I wish I was near enough to see his mechanical apparatus. I find he is engaged in making a curious Orrery. May I ask,” &c.
As further evidence of the high estimation in which the Transactions of the American Philosophical Society, and particularly of the Observers of the Transit, were held abroad, Dr. Wrangel, an eminent and learned Swedish clergyman, wrote thus to Dr. Smith from Stockholm, under the date of Oct. 18, 1771:—“I have been agreeably surprised to observe the rapid progress of your American Society, of which I esteem it a great honour to be counted a member,” &c.—“Your accurate Observations of the Transit of Venus have given infinite satisfaction to our (Swedish) astronomers; as will the rest of your Transactions, to the literary world, when they come to be further known.”
[126]. According to Mr. Lalande, (in his Astronomie, vol. ii.) the transit of Venus over the Sun, in 1639, observed by only Messrs. Horrox and Crabtree, two Englishmen, and which was the first ever observed, was seen in consequence of a fortunate accidental circumstance. He says, that Horrox had been occupied in making calculations for an almanack, from the Tables of Lansbergius, which are much less perfect than the Rudolphine[Rudolphine] Tables: that these Tables of Lansbergius were in an error of 16′ for the latitude of Venus, while the Rudolphine[Rudolphine] Tables had an error of only 8′; but the one of Lansbergius made Venus pass on the sun in such a way, as that the transit ought to be visible; whereas the tables of Kepler represented the planet as passing below him; and thus it was, remarks Lalande, that bad tables occasioned a good observation. Relying on these tables, which Lansbergius had extolled with a confidence likely to produce imposition, Horrox prepared himself to observe that transit; and on the 24th of November, it took place at the time he expected, Venus being about half an hour on the sun when he set. He had sent on the occasion to his friend Crabtree, who was at Manchester, some miles from Hoole: and he observed the transit, likewise; though very imperfectly, by reason of intervening clouds. W.

Flamsted, Halley, Bradley and Bliss, successively occupied the royal observatory at Greenwich, from the time of its institution by Charles II.; and, in the year 1765, the last of these eminent men was succeeded in the place of Astronomer-Royal, by Nevil Maskelyne, B. D. a man who, in the words of the profound French astronomer, Lalande, “has sustained perfectly the reputation of that famous observatory.”
