One door E and one door 1 suffice for the whole furnace. The doors E and F are hung on hinge-* : and when they are in position to close the openings to which they correspond, they are pressed tightly against their seats by screws. The decomposing chambers A. A, A, A. are charged with oxychloride of magnesium, in small pieces, from a tip-waggon charged therewith which has been pre- msly brought into position on the top of the furnace. The oxychloride enters the decomposing chambers by the opening H, Figs, (i and 8. The cover or door which closes this opening is seen in Figs. 6 and 8, but is not marked with any letter. This cover having been removed, a hopper is brought over the opening H, and oxychloride is then poured into the hopper, whence it falls into the chambers A, A, A.
