JACOBSEN'S CHLOR GOLD.

To the Editor of The Colonist. Sht, — I am pleased to inform the public that Mr J. .S. M: Jafiobsen has at last achieved a grand success with his chlor gold. For a long period has Mr Jacobsen been at work trying to convert his chlor gold into marketable yellow gold without success; Recently, however, he has triumphed in acquiring the desired color for his chlor gold, by fluxing it with other native gold. Mr Jacobsen experimented by alloying one-fourth of his metal with threefourths of gold obtained from local alluvial 1 workings, which resulted in forming an 1 alloy of clean yellow gold. This alloy is as ; bard as our British sovereigns. In this ' alloy the chlor gold chemically combines : with the other native gold, and the iridium : in Jacobsen's metal is in such proportions 1 that it brings the gold when so alloyed into 1 a desirable hard metal, whilst it also increases its specific gravity, the specific ; gravity of the said alloy being twenty-two. • Thig brilliant success will be a great boon to Great Britain, as for centuries experi--1 ments have been made by scientists to • manufacture coins free from base metals; 3 but without success, as the alchemists' ■ failures were chiefly due to the fact • that their counterfeit alloys would • not stand proof against acids, or fell . short in retaining the specific gravity • of gold. Mr Jaoobsen's alloy ia proof > against nitric and other simple acids, and > its specific gravity is greater than gold. - This alloy will save an enormous amount of work in coining, whilst coins manufacfactured from it will consist entirely of noble metals. It is important and noteworthy to mention that although Jacobsen's Foft metal is so difficult to analyse, when Blloyed as herein described it can be easily 3 analysed by dissolving it in acqua regia, which produces a clear gold solution, with 1 a residium of iridium and a small percentj age of ruthenium. Mr Jacobsen will shortly go to Nelson to make arrangements for the erection of buildings and plant to manufacture chlor gold from the vast deposit of ore 1 that abounds on his licensed holdings, ' which he has secured from the Govern- , ment. Yours, etc., Joseph Jacobsen. J Takaka, January 2Drd, 1899. i i ~ ~~~ "
