3. Antimony , the grey sulphuret in grains : 4. Realgar , or sulphuret of arsenic ; 
and 5. Manganese , the black oxyde. 
Of earthy minerals, the following : crystalized sulphate and carbonate of lime, 
of rocks, gneiss, granite, &c., and fossil wood, silicified. Also, a bag of spinel rubies, 
or octohedral corundum. 
But the principal object of interest was a button of metal, supposed to be Platina. 
A paper was read by the Secretary on its analysis, which proved, beyond a doubt, 
the existence of the first five of the following ingredients, and rendered the presence 
of the remainder probable.

Tie proportions given were, of course, only approximations, as the composition 
was most complicated, and the quantity devoted to analysis only tea trains The 
spec.fic gravity of the head was 17,2. There could be no doubt, therefore, as to its 
an . ole of Platina ; and Mr. Lane has the credit of the first discovery of 
this precious metal among the gold dust of the Ava mines 1 . 7
