According to Christy, the precipitation with zinc follows equations for 2 according as potassium cyanide is present or not: (1) 4 KAu(CN)2+4Zn+2H20=2Zn(CN)2+ K 2 Zn(CN) 4 +Zn(OK) 2 +4H+4Au; (2) 2KAu (CN) 2 +3Zn+4KCN+2H 2 0 = 2K 2 Zn(CN) 4 +Zn(OK) 2 +4H+2Au; one part of zinc precipitating 3.1 parts of gold in the first case, and 2.06 in the second.
The important discoveries in the Madeleine cave and elsewhere were published by Lartet and Christy under the title Reliquiae Aquitanicae, the first part appearing in 1865.
Christy died before the completion of the work, but Lartet continued it until his breakdown in health in 1870.
HENRY CHRISTY (181o-i 865), English ethnologist, was born at Kingston-on-Thames on the 26th of July 1810.
Encouraged by what he saw at the Great Exhibition of 1851, Christy devoted the rest of his life to perpetual travel and research, making extensive collections illustrating the early history of man, now in the British Museum.
Christy joined the Geological Society, and in company with his friend Edouard Lartet explored the caves in the valley of the Vezere, a tributary of the Dordogne in the south of France.
To his task Christy devoted money and time ungrudgingly, and an account of the explorations appeared in Comptes rendus (Feb.
By his will Christy bequeathed his magnificent archaeological collection to the nation.
Christy took an earnest part in many philanthropic movements of his time, especially identifying himself with the efforts to relieve the sufferers from the Irish famine of 1847.
P. 286), that the human bones and worked flints had been deposited indiscriminately together with the remains of fossil elephant, rhinoceros, &c. Certain caves and rock-shelters in the province of Dordogne, in central France, were examined by a French and an English archaeologist, Edouard Lartet and Henry Christy, the remains discovered showing the former prevalence of the reindeer in this region, at that time inhabited by savages, whose bone and stone implements indicate a habit of life similar to that of the Eskimos.
Moreover, the co-existence of man with a fauna now extinct or confined to other districts was brought to yet clearer demonstration by the discovery in these caves of certain drawings and carvings of the animals done by the ancient inhabitants themselves, such as a group of reindeer on a piece of reindeer horn, and a sketch of a mammoth, showing the elephant's long hair, on a piece of a mammoth's tusk from La Madeleine (Lartet and Christy, Reliquiae Aquitanicae, ed.
To-day anthropology is grappling with the heavy task of systematizing the vast stores of knowledge to which the key was found by Boucher de Perthes, by Lartet, Christy and their successors.
