Gen. Howe admits that the loss in this affair, was 17 killed, and nearly 200 wounded and missing. But the Americans say, they have taken near 300 prisoners, of whom 14 are officers, all British. Capt. Leslie, the son of the earl of Leven, who was killed in the engagement, was buried by the Americans with the honors of war, not only as a British officer, but in testimony of respect to his lordship’s worth. The American officers commended the bravery of the troops under colonel Mawhood; one of the generals, observing how they fought, exclaimed, “When will our men fight like those fellows!” General Mercer met with hard usage, being bayoneted in three places, of which wounds he is since dead. He was a deserving character, and merited different treatment. Some may pronounce the treatment that captain Philips, of the thirty-fifth grenadiers, has met with, much baser; but not when they have the case properly represented.—The captain, as he was returning from New-York, to join his company, was surprised between Brunswick and Princeton, by a party of militia, who threatened him in case he attempted to escape; regardless of the threat, he clapped spurs to his horse and pushed forward, on which they fired and killed him. General Gates, who is married to the captain’s sister, blames the captain more than the men. The eagerness of the royal army to reach and secure Brunswick, occasioned their marching through Princeton with such expedition as to divert their attention from either carrying off or destroying the curious orrery belonging to Nassau college. It was contrived and made by an original genius and self-taught astronomer, Mr. Rittenhouse of Philadelphia. There is not the like in Europe. An elegant and neatly ornamented frame raises 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 round the sun, and the satellites about the planets. The wheels, &c. that produce the movements, are behind the wooden perpendicular plane, on 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 lord Cornwallis intended to have carried it over to Great-Britain; no man of conscience can blame his taste, which may have preserved it from ruin, by securing to it that protection while in the hands of the enemy, that might otherwise have been denied. But the children of the _alma mater_, whose it is, triumph in its preservation, though somewhat damaged. The college library did not escape so well as the orrery; but suffered considerable.
