Rare sea chart of the northern portion of the Strait of Malacca, from Laurie & Whittle's East India Pilot.
The chart includes rhumb lines, depths, shoals, a compass rose and a detailed inset, "Plan of Poolo Pinang, now Prince of Wales's Island, with its straits and harbour...".
The coast lines are illustrated with topographical cross sections.
Published in "The East-India Pilot, or Oriental Navigator, on One Hundred and Eighteen Plates: Containing a Complete Collection of Charts and Plans, &c..." The chart is based on the 1745 French "Neptune Oriental" by Jean Baptiste Nicolas Denis d'Apres de Mannevillette, supplemented by English navigators.
Laurie & Whittle refers to the partnership of Robert Laurie (1755?-1836) and James Whittle (1757-1818), engravers and map publishers. Both men were employed by Robert Sayer (ca. 1724-1794), one of the most prominent British publishers and map sellers of the eighteenth century. Sayer died in 1794 and his business was taken over by his assistants. The two worked together as Laurie & Whittle until 1812, when Laurie retired. They were especially known for publishing sea charts and maritime atlases. From 1812-1818, when he died, Whittle worked with Laurie’s son, Richard Holmes Laurie, as Whittle & Laurie. After 1818, the firm was known as R. H. Laurie, even though Richard died in 1858. Later, the firm was managed by Laurie’s draughtsman, Alexander George Findlay, and, later, Daniel and William Kettle.
