Note 120 — MEMOIRS OF THE LIFE OF DAVID RITTENHOUSE; ANTERIOR TO HIS SETTLEMENT IN PHILADELPHIA.

The first volume of the Society’s Transactions contains (p. 125,) among other observations of the transit of Venus in 1769, those made at Baskenridge in New-Jersey, by the late Earl of Sterling. William Alexander, the gentleman referred to, and who held this title, was (it is believed) a native of New-York. It is presumable that the title he bore was one to which he had an equitable right: It was recognized in America, the country of his birth, from the time of his first assumption of it until his death, although his claim to that honour was not juridically established in Great Britain, where, in official acts of that government, he was styled “William Alexander, Esq. claiming to be Earl of Sterling.” He was descended from Sir William Alexander, in the reign of James I., to whom that monarch made a grant of the province of Nova Scotia, on the 20th of September, 1621. On the 12th of July, 1625, Sir William obtained from King Charles I. a grant of the soil, lordship and domains, of that province, which, with the exception of “Port-Royal,” (Annapolis, on the Bay of Fundy,) formerly the capital of the province, he conveyed on the 30th of April, 1630, to Sir Claude de St. Etienne, lord of la Tour and Uarre, and to his son Sir Charles de St. Etienne, lord of St. Deniscourt, on condition that they should continue subjects to the crown of Scotland. This Sir William was appointed by Charles I. commander in chief of Nova-Scotia. Soon after the institution of the order of Baronets of Nova-Scotia, he had been advanced to that dignity by Charles I. viz. on the 21st of May, 1625; when the king conferred on him the privilege of coining copper-money. In 1626, he was created Viscount Sterling: and on the 14th of June, 1633, he was further promoted by the same king to the Earldom of Stirling.

The late Lord Stirling, who was seated at Baskenridge in New-Jersey, inherited his Baronetage and titles of Nobility, as heir-male to Henry, the fourth Earl. He married Sarah, daughter of Philip Livingston, Esq. of New-York, by whom he had issue two daughters; Lady Mary, married to —— Watts, Esq. of New-York, and Lady Catharine, first married to William Duer, Esq. of New-York, and after his decease to William Nelson, Esq. of the same city.

This nobleman appears to have been in some degree skilled in astronomy, and was reputed a good observer. In the first volume of the Transactions of the American Philosophical Society there is contained, besides his lordship’s observations of the transit of Venus, a letter from him to Dr. Smith, communicating an account of his having discovered, on the 28th of June, 1770, a comet, which he observed astronomically on that and the three succeeding nights; being the same that Mr. Rittenhouse first saw on the 25th of that month; and respecting which, there are two letters from him to Dr. Smith, in the same volume.

Immediately before the American revolution, lord Sterling was one of the king’s council in New-Jersey; and held also, under the crown, the appointment of surveyor-general for the eastern division of that province. With the talents of a philosopher, he united those of the soldier: On the 1st of March, 1776, his lordship was appointed a brigadier-general in the continental army, and was afterwards promoted to the rank of major-general. He was esteemed a brave and faithful officer, and served with reputation; but he died before the close of the war.

In the same volume of the Transactions of the American Philosophical Society, with lord Stirling’s observations, there are, independent of those made under the direction of that society, the observations of the transit of Venus in 1769, made at Cambridge in New-England, by John Winthrop, Esq. F. R. S. and member of the American Philosophical Society, Hollisian Professor of Mathematics in Harvard-College—(see p. 124;) likewise, the result of those made by captain Holland and Mr. St. Germain, at and near Quebec; and by other skilful observers, at sundry places in Europe and the West-Indies; all reported (p. 120) by a committee of the American Philosophical Society.
