principal advantage is the greatly increased weight.When clean and whole it gives more light, and is saferthan the Davy. In case of use in dangerous places, andwhen dirty it is probably inferior.—D. T. A.]

Vielle Montagne, Liege . (Agent, H. F. Sclnnoll,12 Manchester Buildings, Westminster.)
Haw ore, in the piece, and w r ashed. Ore, calcined andground. Ore and charcoal, mixed for the furnaces.
Baw zinc. Sheet zinc of all kinds, for roofing, ship’ssheathing, paper-dressing, household utensils, tin-smith’swork, &c. Bars, for ship nails. Drawn zinc, for nails ofall kinds. Brass.
An assortment of chemical compounds, made of zinc.Grey oxide, for paint. Cement, for boilers.
[The Vielle Montagne Mining Company has long beenknown as working large quantities of the common zincore of Belgium (calamine), and introducing the metal intothis country at rates which render the working of blende(or sulphuret of zinc) of England not profitable. Thezinc is used for many purposes, as well directly to replacelead and tiles in roofing and covering buildings, &c., asindirectly to supersede partly the white lead of commerceby the oxide of zinc prepared for this in a particular way.Zinc has very much more tenacity than lead, and is verymuch lighter for roof work than slate, tiles, or lead. Thezinc made by the Vielle Montagne Company is extremelypure, containing only a little iron and some traces of leadand sulphur.—D. T. A.]

32 Wautelet, J., for the Charbonnage d’Oignies-
Specimens of semi-bituminous coal, adapted for drying-houses and domestic fuel.
[The Hainault coal occupies a surface of upwards of200,000 English acres, and includes, as will be seen, bothbituminous and anthracite kinds. There are, in all,114 different seams in the district, the greatest expansionof which, near Charleroi , is of great industrial interest.There are three distinct kinds of coal, viz., 1st, the upperor Henu coal, which burns easily and rapidly, with muchflame and smoke, and is adapted for steam-boilers ; 2nd,the middle or bituminous coal, well adapted for cokingand for the forge, and also for domestic purposes ; and3rd, the lower or anthracitic coal—friable, contains littlebitumen, but bums with much heat and very slowly.The workings for coal in the Mons district are carried onat considerable depth, the upper beds being 1,000 feetdeep.—D.T.

38 Societe de Floreffe, Floreffe , Namur.
Specimens of anhydrous sulphate of soda; anhydrous
carbonate of soda; salt of soda, a combination of thepreceding; impure caustic soda, and crystals of carbonateof soda.
[The rock salt of commerce, and granular salt, whichconsist chemically of chloride of sodium, are the primesoiu-ces of this valuable chemical product. Formerly, bothsoda and potash were obtained by burning sea-weed.Soda of commerce is now prepared from salt, by mixingthe latter with sulphuric acid, so as to form a sulphate ofsoda, in a reverberating furnace. The sulphate of soda,or saltcake, is decomposed by chalk and ground coal,which are mixed with it, and is then exposed to a hightemperature. The mass is afterwards washed, and thesolution purified and crystallized. Carbonate of soda isformed by heating the impure alkali with sawdust, orother carbonaceous matters, washing the residue, andcrystallizing. By an ingenious combination of processes,muriatic acid, and bleaching powder, commonly calledchloride of lime, are made also in alkali works. Some ofthese establishments are among the most extensive of anyconcerned in the industrial arts. The crystallizing houses,in connection with manufactories of this description inGreat Britain, present a wonderful and interesting spec-tacle in the long rows of pans and masses and crystallizedalkali which are arranged in order throughout their ex-tent.—B.
