PORTSMOUTH, Oct 17.The officers and crew of the Comet have at last returned to that vessel from the Fire Queen, and the latter has been laid up alongside the Britannia, 120, in charge of her engineers and stokers for the present. Rumour states that there is to be a complete change in regard to the tenders, which are in future to be steamers instead of sailing vessels, Undine and Fire Queen superseding Fanny, Emerald, and Mercury, at this port.
