A detailed chart of the Channel with particular attention to the movements of tides and currents from the observations of Captain Edmond Halley. The coastlines of southern England and northern France are well mapped, extending from Brittany to Calais, and from Suffolk to Cardigan, with a portion of the Irish coast and the Isles of Scilly. Sandbanks, soundings, and hazards are all meticulously noted. An Advertisement in the lower right hand corner describes how the mariner is to make use of the chart. Sold by Sellers & Price.
