N. SPON: LONDON AND NEW YORK * * * * * * Transcriber's note: A Table of Contents was added for the convenience of the reader. Hyphenation has been made consistent except where the meaning would be affected. Metre and centimetre changed to mètre and centimètre for consistency; all other accentuation unchanged. Original spelling has been retained with the exception of 'guage,' which has been changed to 'gauge;' Parimaribo changed to Paramaribo; filteration changed to filtration; homogenous changed to homogeneous. Suction 'powder' appears to be a misprint for 'power' and has not been changed. Some illustrations are not referenced in the text and have no title, e.g. Fig. 10. Descriptive titles were added by transcriber where needed in the plain text version only. 'P. S. Reed' is mentioned in several places and is probably a misprint for 'Reid'; see NEIMME Library. H. S. Merritt changed to H. S. Merrett.
