The unfortunate catastrophe, which produced such an awful result to Major Campbell, it is hoped will not fail to leave a lesson to mankind of salutary influence. Both of the parties were gentlemen, eminent in their profession, of high character and honour, who had long lived on terms of mutual friendship and esteem. The unfortunate irritation of a moment, at once deprived society of one of the best of men, and left a widow and infant family to mourn their irreparable loss. Retribution of the most awful kind fell to the lot of the other; and his amiable widow and helpless family were also involved in all the distress which the human mind can conceive. From the period of the unhappy event to the closing of the tragic scene, Major Campbell evinced the most heartfelt grief for what had happened to his friend. BETWEEN LORD PAGET AND THE HON. CAPT.

In order to prevent the appearance in the papers of any mis-statement respecting the duel which took place this morning between Lord Paget and Captain Cadogan, we, the respective friends of the parties, feel it incumbent on us to submit the following as the correct statement of the event as it occurred:— In consequence of a challenge having been received by Lord Paget from Captain Cadogan, and every attempt to prevent a meeting having failed, the parties, attended by their respective friends, Captain Cadogan by Captain Mackenzie of the navy, Lord Paget by Lieut.-Colonel Vivian of the 7th Light Dragoons, met, as agreed, at seven o’clock, on Wimbledon Common.

Both the seconds being clearly of opinion that such was not his intention (although the degree of obliquity he gave to the direction of the pistol was such as to have been discovered only by particular observation), Captain Mackenzie stated to Captain Cadogan, that as it appeared to be Lord Paget’s intention not to fire at him, he could not admit of the affair proceeding any farther. Lieut.-Colonel Vivian then asked Captain Cadogan whether he had not himself observed that Lord Paget had not aimed at him, to which he replied in the affirmative. Captain Mackenzie then declared his determination not to remain any longer in the field, to witness any further act of hostility on the part of Captain Cadogan. Captain Cadogan replied, that of course his conduct must be decided by his second; declaring, at the same time, that he had come prepared for the fall of one of the parties. On Captain Mackenzie and Lieut.-Colonel Vivian making it known to Lord Paget, that as he evidently did not intend to fire at Captain Cadogan, the affair could go no farther; his lordship replied, “As such is your determination, I have
