After chargingthe cylinders with the lead, each 4,000 lbs. is treated with asolution which contains 14 lbs. of 28 per cent, acetic acid toabout 40 lbs. of water. This solution is prepared separatelyin a small cask, or tank, running on a trolly on rails betweenthe various tiers of tanks, and connected by a flexible hose toan air-pipe coming from the air compressor, from which tankit is spread over the lead in the cylinders in quantities suffi-cient to make the whole mass thoroughly moist, and to anextent which has been found by experience to be hand-hole doors are then fastened on the front end of. The New Lead-Corroding Works at Montreal.—The corroding tanks or cylinders. These are arranged in ranks of twenty, and are rotated by means of a spur-wheel and worm-gearing. flows through a pipe connected with the bottom of the kettle,and the stream of lead, approximately three-eighths of an inchto one-half inch in diameter, in its passage through this pipeis atomized. There is connected to this pipe, in the mannerof an inspirator, another pipe connected with the boiler, andthi-ough which is blown a jet of steam. The action of thissteam on the molten lead is to atomize it, or blow it intominute particles, ranging from dust to perhaps 1-64 of aninch in diameter, and which are carried by the force of thesteam jet into a condensing chamber, where the fumes anddust are both collected. The efifect of this atomizing is notalone mechanical, but to a certain extent is chemical andoxidizing in its action, the resulting atomized lead showing a the t
