This morning a Dane made a signal for a boat from hence, when two went to her, and brought on shore here twenty-five seamen who had been put on board the Dane by an American privateer in the Bay; they were the crew of two prizes, one of them a store ship, bound to Quebeck, and the other a vessel bound to the West Indies; they give an account of the privateer's having taken 11 prizes, and that the Captain said he would return to Boston as soon as he had made up his dozen. She is called the Tyrannicide.
