This pair of charts of the China Sea was published by James Horsburgh, hydrographer for the British East India Company (EIC). When combined, the two sheets constitute a complete chart of the China Sea, and include additions made in 1859 to the original charts published by Horsburgh in 1821. They offer detailed navigational information of what is today China and Southeast Asia, including Singapore, and were dedicated to Captain Daniel Ross, the hydrographer for the EIC who accompanied Raffles and Farquhar to Singapore in 1819.
