A second telegram concerning the death of Captain Brownrigg. of H.M.S. London, has been received at the Admiralty, from which it appears that two of the wounded men, Venning and Tallis, have recovered ; and the third, Massey, is progressing favourably. The dhow was flying French colours, and when the London's boat ran alongside to verify its nationality, the Arab crew fired a volley and immediately boarded the boat, killing, wounding, and driving the crew overboard. Captain Brownrigg made a most gallant resistance, receiving twenty-one wounds, and falling at last, shot through the heart. The dhow, which is stated to have been full of slaves, has since been captured empty; but some Arabs suspected of belonging to the crew have been arrested by the Sultans troops.
