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.
