It was discovered in 1886 by C. Winkler in argyrodite, a mineral found at Freiberg in Saxony.
When passed with carbon dioxide through a red-hot tube it yields carbon oxysulphide, COS (C. Winkler), and when passed over sodamide it yields ammonium thiocyanate.
C. Winkler decided the atomic weight of germanium by similar reasoning.
Tupaya, a Tahitian, who accompanied Captain Cook in the " Endeavour " to Europe, supplied his patron with maps; Raraka drew a map in chalk of the Paumotu archipelago on the deck of Captain Wilkes's vessel; the Marshall islanders, according to Captain Winkler (Marine Rundschau, Oct.
Winkler (1703-1770), professor of physics at Leipzig, substituted a leather cushion for the hand.
In 1756 he accepted the invitation of Gottfried Winkler, a wealthy young merchant, to accompany him on a foreign tour for three years.
They did not, however, get beyond Amsterdam, for the outbreak of the Seven Years' War made it necessary for Winkler to return home without loss of time.
Ann., 1875, 156, p. 466) on electrolysis of the fused chloride, while C. Winkler (Ber., 1890, 23, p. 78) prepared it by heating the oxide with a mixture of magnesium and magnesia.
It combines with water with evolution of heat, and on heating with magnesium powder in an atmosphere of hydrogen forms a hydride of probable composition La 2 H 3 (C. Winkler, Ber.
157171); by passing chlorine into milk of lime (C. Winkler, Jour.
Ann., 1875, 156, p. 466); and C. Winkler (Berichte, 1891, xxiv.
Peligot), by electrolysis of nickel ammonium sulphate (Winkler, Zeit.
Winkler discovered that an iron chain wound round the bottle could be substituted for the hand, and Sir William Watson in England shortly afterward showed that iron filings or mercury could replace the water within the jar.
Winkler de Ketrszynski, Vita sancti Stephani (Cracow, 1897).
This reaction, now known by the name of the catalytic or contact process, was made the subject of a patent by Peregrine Phillips, in 1831, and was tried later in many ways, but had been always considered as useless for practical purposes until 1875, when it was simultaneously and independently taken up by Clemens Winkler in Freiberg, and by W.
Winkler showed that this division was best obtained by soaking asbestos with a solution of platinum chloride and reducing the platinum to the metallic state, and he described later a specially active kind of "contact substance," prepared from platinum chloride at a low temperature.
This salt on strong ignition leaves a residue of the trioxide, which can be converted into the metal by heating in a current of hydrogen, or by fusion with sodium (C. Winkler, Journ.
The atomic weight of indium has been determined by C. Winkler and by R.
Clemens Winkler contributed two works, Anleitung zur chemischen Untersuchung der Industriegase (1876-1877) and Lehrbuch der technischen Gasanalyse (2nd ed., 1892), both of which are very valuable for the commercial applications of the methods.
For a good many years the further development of this industry was surrounded by great mystery, but it is now known that a satisfactory solution of the difficulties existing in the above respect was attained in several places, for instance, at Freiberg and in London, by the labours of the original inventors, Professor Winkler and Dr Messel.
