4,24, Dr. Wollaston on a new Metal , 
evaporated, did not crystallize ; the residuum was soluble in 
alcohol, and of a rose colour. Sal ammoniac, nitre, or common 
salt, caused no precipitation from the muriatic solution; but 
formed triple salts, which were not soluble in alcohol. 
(D 2.) The solution in nitric acid also did not crystallize. 
A drop of this solution, being placed upon pure silver, occasioned 
no stain. On the surface of mercury a metallic film was preci- 
pitated, but did not appear to amalgamate. The metal was also 
precipitated by copper and other metals, as might be presumed, 
from the usual order of their affinities for acids. 
(El.) The precipitate obtained by zinc (C 2.) from the re- 
maining half of the salt, appeared in the form of a black powder, 
weighing, when thoroughly dried, nearly 2 grains, corresponding 
to about 4 grains in the 1000 of ore dissolved. 
(E 2.) When exposed to heat, this powder continued black; 
with borax, it acquired a white metallic lustre, but appeared 
infusible by any degree of heat. 
(E 3.) With arsenic, however, it is, like platina, rendered 
fusible; and, like palladium, it may also be fused by means of 
sulphur. The arsenic, or the sulphur, may be expelled from 
it by a continuance of the heat; but the metallic button obtained 
does not become malleable, as either of the preceding metals 
would be rendered by similar treatment. 
(E 4.) It unites readily with all metals that have been tried, 
excepting mercury; and, with gold or silver it forms very mal- 
leable alloys, that are not oxidated by a high degree of heat, 
but become incrusted with a black oxide, when very slowly 
cooled. 
(E 5.) When 4 parts of gold are united with 1 of rhodium, 
although the alloy may assume a rounded form under the
