mitis (mitis)

[NL. use of L. mitis, mild, gentle.] A South American cat: same as chat i, mitis-casting (mi'tis-kasting), n. The name given by P. Ostberg, the inventor of the proce , to a method of increasing the fluidity and lowering the fusing-point of iron and steel, by adding a small quantity of aluminium (about half of one per cent.) to the charge in the crucible the moment it has been melted. This is said greatly to facilitate the casting proce , and to add to the strength of the metal. The aluminium is added in the form of an alloy of 6 to 10 per cent, of that metal with iron. This alloy is made by a patented proce consisting, as is stated, in adding clay to the iron in the proce of smelting. The mitis-castings are said to be rapidly taking the place of malleable-iron castings.
