Alexander John Gaspar Marcet (1770-185) was a Swiss-British physician and chemist that carried a detailed study of the waters from different oceans and lakes, particularly those of the Dead Sea; with Berzelius determined the properties and correct composition of carbon disulfide and the strong cooling effect of its vaporization; designed a powerful alcohol lamp; studied the synthesis of nitrogen trichloride, compared the composition of the chyle produced from strictly vegetable and meat diets, and confirmed Wollaston’s (wrong) belief that diabetic blood did not contain sugar and that sugar passed directly from the stomach to the kidney, without participation of the blood torrent.

Keywords : Dead Sea water; carbon disulfide; chyle; chyme; nitrogen trichloride; sugar in blood.
