Nassau Hall, the principal edifice of the College of New Jersey, is a spacious building, one hundred and seventy-six feet long, fifty wide, and four stories high, built of stone. It was erected in 1757. The college was commenced by Jonathan Dickinson, in Elizabethtown, and was first incorporated in 1756. Governor Belcher was one of its earliest and most efficient patrons. He made "generous donation of his library of books, * with other valuable ornaments," to the college; and, upon his recommendation, Nassau Hall was so called in memory "of the glorious King William the Third, who was a branch of the illustrious house of Nassau." The Hall stands in the center of spacious grounds, fronting on the principal street in Princeton. The edifice on the left of Nassau Hall, containing the college library and the philosophic hall, was erected after a conflagration in 1802. The library contains about eight thousand volumes, and the libraries of two societies of the institution about four thousand more, making twelve thousand volumes. There is also a mineralogical cabinet, a museum of natural history, and a fine collection of drawings made for the purpose of elucidating lectures on astronomy and architecture. There is also a good collection of philosophical apparatus there, which includes that wonderful piece of scientific mechanism, the planetarium of Doctor David Rittenhouse. ** Through the politeness of Professor MacLean, I was permitted to examine its construction, and view the wonderful precision with which the machinery performed its difficult functions. On the front is inscribed,
"INVENTED
BY DAVID RITTENHOUSE, A.D. 1768;
REPAIRED AND EXTENDED BY HENRY VOIGHT,
1806;
BOTH OF PHILADELPHIA."
Dr. Gordon, writing in 1790, says of this planetarium, "There is not the like in Europe. An elegant and neatly-ornamented frame rises perpendicular near upon eight feet, in the front of which you are presented, in three several apartments, with a view of the celestial system, the motions of the planets around the sun, and the satellites about the planets. The wheels, &c., that produce the movement are behind the wooden perpendicular frame in which the orrery is fixed. By suitable contrivances, you in a short time tell the eclipses of the sun and moon for ages past and ages to come; the like in other cases of astronomy." It is said that it was Lord Cornwallis's intention to carry this planetarium away, and take it to England with him; but the Americans kept him too busily engaged in affairs of greater personal moment, while in Princeton, to permit him to plunder the college of this great treasure. This intention on the part of an enemy was not as reprehensible as the proposition which Silas Deane, the American commissioner, made, who suggested the propriety of presenting it to the French government as a bonus for its good will!
I have mentioned that the first cannon-ball which entered Nassau Hall, when Washington opened a fire upon it, passed through the portrait of George the Second, and destroyed it. The frame was uninjured, and left suspended upon the wall. It is alleged that Wash-
* It consisted of four hundred and seventy-four volumes, many of them very rare and of great value. The Hall being used alternately by the American and British troops during the war, a large portion of the books were purloined or destroyed. The few that remained were destroyed by fire in 1802, when the Hall was burned, leaving nothing but the strong walls, which were not materially injured by the fire.
* David Rittenhouse was born near Germantown, Pennsylvania, on the 8th of April, 1732. His ancestors were from Holland. His early life was spent in agricultural pursuits, and was marked by a love of mathematical studies. Feeble health would not allow him to pursue the labor of a farm, and he became, by self-instruction, a proficient clock and mathematical instrument maker. It was while working at his trade he planned and executed his orrery, a piece of mechanism far superior, for its intended purposes, to any thing before constructed. It was purchased by the College of New Jersey. Another was made by him, after the same model, for the College of Philadelphia. He pursued his trade in that city for several years. His first philosophical publication was an account of his calculations of the transit of Venus, as it was to happen on the 3d of June, 1769. He observed the phenomenon, a spectacle never seen but twice before by an inhabitant of earth, and he was so much affected by its proof of the accuracy of his calculations, that he fainted. He was engaged in government surveys, fixing territorial boundaries, &c., during the Revolution, and became one of the leading practical philosophers of the day. On the death of Franklin in 1791, he was chosen president of the Philosophical Society, which office he held by annual election until his death. He was treasurer of Pennsylvania from 1777 to 1789. In 1792 he was appointed director of the Mint of the United States, but his ill health compelled him to resign the office in 1795. He died on the 26th of June, 1796, aged sixty-four years. His birth-place is yet standing, a mile west of Germantown.

ington, in order to make good to the college the damage sustained by the cannonade, made the trustees a present, from his private purse, of two hundred and fifty dollars, which sum they, expended in procuring a full-length portrait of the eommander-in-chief.
