[215]. The difference of 16′ 42″, between the latitude above mentioned and the beginning of the 40th degree of north latitude, (which was the southern limit assigned to Pennsylvania, by her charter,) was gained by Mr. Penn, as far as the northern boundary of Maryland extended westward, in consequence of a compromise entered into by him and Lord Baltimore; whereby the latter obtained some advantage on his part in return. From the western extremity of this northern boundary of Maryland, the line between Pennsylvania and Virginia was continued, westward, in the same parallel of latitude, (instead of these coming back to the 40th deg. of N. lat.) by virtue of an agreement between these two states; the former, in consideration of that privilege, relinquishing her right to run her western boundary line parallel to the meandrings of the river Delaware.

[216]. “Principem Philosophorum,” in the original:—Such was the appellation (Principes Philosophorum) by which Cicero honours Pythagoras, Democritus, Plato, Xenocrates, Zeno, Cleanthes, Diogenes the Stoic; men, among others, whose usefulness (he observes) old age might diminish, but not destroy.

[217]. Mr. Boyle was the seventh son of Richard, the first earl of Cork, in Ireland, and first earl of Burlington, in England; and was born at Lismore in Ireland, the 26th of January, 1627[1627]. This eminent philosopher and sincere Christian established, by his will, in the year 1691, a perpetual fund, equivalent to about two hundred and twenty-two dollars per annum, for instituting a course of eight sermons or lectures, to be delivered annually; designed to prove the truth of Christianity, generally, without engaging in any of the controversies subsisting among its professors: And to this establishment, denominated Boyle’s Lectures, the world are indebted for many able and elaborate defences both of natural and revealed religion. In addition to several extensive benefactions, for charitable and religious purposes, of this great and excellent man, besides his donation to the College of William-and-Mary (which, according to Mr. Jefferson, was “considerable” in its amount,) he gave, in his lifetime, a sum equivalent to thirteen hundred and thirty-three dollars, towards propagating the Christian Religion in America. So great was his veneration for the name of God, that he never pronounced it without a discernible pause: he was steady in his secret addresses to the throne of heaven: and, amidst all his enquiries into nature, his chief design seemed to be that of continually elevating his own mind, and the minds of others, by contemplating the Glory, the Wisdom, and the Goodness of God. Were this illustrious man to be considered in no other point of view, than that of a benefactor to America, his memory would be entitled to respect in this country: but his virtues, his talents, and the services he has rendered to mankind in general, will for ever endear his name to the good and wise of all nations. He died the 30th of December, in the year 1691.

[218]. The author of a poem, entitled, ‘The Dying Negro,’ has introduced these lines into that poem:[[218a]]

“Oft have I seen them, at the break of day,

“Rous’d by the lash, go forth their cheerless way.”

No man ever held the slave-trade, and the condition of the hapless people who are the objects of that nefarious traffic, in greater abhorrence, than the benevolent Rittenhouse: a passage in his Oration, fully evinces his sentiments on this subject.

In addition to this highly respectable testimony against Negro Slavery, let it be remembered, that one of the last acts, of a public nature, in which our philosopher’s predecessor[[218b]] was concerned, was to sanction with his name the Memorial presented to the government of the United States, on the subject of the Slave-Trade, by “The Pennsylvania Society for promoting the Abolition of Slavery, and the relief of free Negroes, unlawfully held in Bondage;” of which Society, that distinguished man was the President.
