This work was illustrated with 26 tinted lithographs of natives and scenery in Sri Lanka after drawings from nature by the author, of which four were colored reproductions of underwater scenes made by the author using a diving bell he commissioned for the purpose. The plates were captioned in German, English, and French. An edition in German was issued from Braunschweig in 1868. Digital facsimile from Biodiversity Heritage Library at this link.
