At the end of July, the H.C. steamer Phlegethon, Lieut. M'Cleverty, nearly the exact counterpart of the Nemesis, arrived at Hong-Kong, bringing the intelligence that Captain Elliot's treaty of Chuenpee had been disapproved of by the home government, and that Sir Henry Pottinger had been appointed to succeed him, as sole plenipotentiary. Shortly before this, also, her Majesty's 55th regiment had arrived from Calcutta, and everything indicated that a movement upon Amoy would take place as soon as possible, after the expected arrival of Sir Henry Pottinger as plenipotentiary, and Sir William Parker as admiral. The season for active operations was already advanced, and even for the sake of the health of the troops, it was the anxious wish of all the officers that a change of some sort or other might speedily take place. In the afternoon of the 10th of August, the arrival of the H.C. steamer Sesostris, from Bombay, in the Macao roads, was announced, and great was the joy of every one when it was made known that both Sir Henry Pottinger and Sir William Parker were on board. They had come from London in the wonderfully short period of sixty-seven days, ten of which had been spent in Bombay. At daylight next morning, the Nemesis went out to convey these high functionaries from the Sesostris, in the roads, to the town of Macao, where they were received with every demonstration of respect, under a salute from the Portuguese forts. A conference was held in the course of the morning, between Captain Elliot and Sir Henry Pottinger, together with the Admiral and Sir Hugh Gough. Energetic measures appeared to be at once resolved on. Sir William Parker went over to visit the fleet at Hong-Kong, and as soon as visits of ceremony had been exchanged between the new plenipotentiary and the Portuguese authorities, Sir Henry Pottinger lost no time in publishing the notification of his appointment, as minister extraordinary and sole plenipotentiary, and also as chief superintendent of trade in China.
