Art. XXXIV.—A new Metal in the Native Platinum of Rogue 
River, Oregon ; by C. F. CuanpLer, Professor of Chemistry 
at Union College. 
a ea ago, 1 became convinced of the probable existence 
of a hitherto unobserved metal. I have deferred publishing my 
in hydrochloric acid on the application of heat, but the solution 
thus obtained had no effect on a solution of protochlorid of mer- 
cury (HgCl), and on cooling deposited a small quantity of minute 
crystals, To guard against error these experiments were —— 
ie or three times on small portions of the original solution, 
‘Ways with the same result. 
_The chlorid of this metal differs therefore from the protochlo- 
of tin, in not reducing protochlorid of mercury to calomel, 
and in being but slightly soluble in the cold. 
N mentioning my observations to a friend, I was referred to 
Dr, FA. Genth’s announcement of a new metal, made in 1852, 
are. : 
h occurred among grains of 
Platinum from California. It was malleable; it fused readily on 
. ox . E ; 
became Opalescent on cooling; it was dissolved by hot hydro- 
chloric acid and by nitric acid; and its solution gave a brown 
therefore that the metal which 
River platinum, is identical with that observed by Dr. Genth.
