This afternoon, the long-subsisting difference between Lord Townshend and the Earl of Bellamont was finally decided in Marylebone Fields, when the latter received a ball in the right side of his belly, near the groin. They were armed with small swords, and a case of pistols; but it was agreed to use the latter first. Lord Townshend fired first, which gave the unfortunate wound, and Lord Bellamont discharged his pistol immediately after, without effect. The seconds were the Hon. Mr. Dillon for Lord Bellamont, and Lord Ligonier for Lord Townshend. Lord Bellamont was immediately taken up and put into a chaise; but from the agony arising from his wound, he could not bear the motion. A chair was, therefore, immediately sent for to carry him to his lodging, where, on his arrival, he desired to be laid on his back. Mr. Bromfield and other surgeons were immediately called in, who endeavoured, but in vain, to extract the ball. His lordship ultimately recovered after great suffering. BETWEEN MR. SCAWEN AND MR. FITZGERALD. September 1, 1773. This day a duel was fought between Mr. Scawen and Mr. Fitzgerald, near Lisle, in which neither of the gentlemen received any hurt. Mr. Fitzgerald fired two pistols, one by design and one by accident. Mr. Scawen fired one in the air, when making some slight apology for the cause of the duel, the parties were reconciled, and returned highly satisfied with the issue of the affair. BETWEEN MR. WHATELY AND JOHN TEMPLE, ESQ., December 11, 1773. A duel was fought in Hyde Park, between Mr. Whately, brother of Mr. Whately, late Secretary to the Treasury, and John Temple, Esq., Lieutenant-Governor of New Hampshire, when the former was dangerously wounded. The cause of quarrel was—the discovery of the confidential letters written by Messrs. Hutchinson, Oliver, Paxton, &c. &c., which were lately laid before the Assembly at Boston, and have been since published in most of the London papers. * * * * * Soon after this duel was fought, the following information was given to the public by Doctor Franklin:—
