An improvement on this method was patented by JohnThorn, and is here shown:— TJionCs Sulphurinr/ Appnratns.—Fir/. 138.

There are two windows, which are placed opposite each other, f is a cast-iron tray for burning the sulphur. It is placed on a flag, inclining towards the chamber atabout one inch to a foot. It is furnished with a slide, on which to put the sulphur to bepushed in, and to admit what air may be wanted. The space for air may be from half aninch to an inch wide. It costs £18 to £20. Preparation.—Pad the pieces, previously well bleached, (see Bleaching,) in a woodenpadding machine through stannate of soda at 10° twice over, then pass through a cistern- with rollers, containing dilute sulphuric acid at 3° T., wash gently, and partially dry, thenpad through sulphomuriate of tin at 4° T. twice.
