PLATINUM.
TO THE EDITOR. Sir,—Mr Henry Rose asks for information for saying platinum. There is no more difficulty iv saving platina than line gold; the only difference is that fine gold amalgamates with quicksilver, and is therefore extracted from the black sand, whereas platinum will not amalgamate with quicksilver, and therefore the panuings off requires . a streaming down —if in quantities, on plush first, and afterwards on baize or calico. When dry, a strong magnet may he useful in extracting what particles of irousand remain.—l am, &c.' Archik.'.i.d Butx.ee, i Dunedin, March 19. Miner.
