The quantity reduced was so smail, and the balance I used

In color, hardness, and malleability, it corresponds exactly

“ In muriatic acid, with a gentle heat, it was entirely dis- 
solved, Hence I infer its comparative freedom from those 
alloys which eae as a black powder when common tin is 
dissolved in this acid. 
While the solution thus obtained was in the state ae a pro- 
tomuriate, the following tests of tin were applied. com- 
parative experiments, a piece of common block tin was dis- 
solved in muriatic acid, and the same tests applied. Jn every 
case the results were exactly alike. 
1. Muriate of platinum gave a deep orange precipitate. 
5 Muriate of gold, a purple do. 
3. Ferrocyanate of potassa, a white do. slight-
