Southeast Asia is on the last sheet of this map of Asia. The South China Sea is labelled ‘Malayan Sea’. Small islands, shoals and reefs are shown. A label in Cochin China (Vietnam) reads ‘mountains inhabited by the uncivilized people called Kemoys’.

Nautical charts like this are detailed around the coasts and on the seas (e.g. river mouths, islands, shoals and reefs) while the interiors are blank. The web of lines is a rhumbline network, while the numbers indicate sea depth (bathymetry).
