 ... to analysis, and found to contain carbonates of lime and magnesia; silica, alumina, and oxides of iron; and of— Copper (metallic) . . . .5.72 per cent. b. A portion of the copper mineral, from which the rock or vein-stuff had been detached as far as practicable, was found to consist of impure hydrated silicate ...

... stiff clay, often of great thickness, produced by the disintegration of the rocks;* [An analysis of the soil will be found in the Appendix.] the clay makes excellent bricks, and often contains nearly 30 per cent. of alumina. ...

... approach and goals are more dynamic than those of Browne, and he attempts to analyze various embryonic fluids by coagulation and distillation procedures. His experiments reveal, for example, that "coagulations" effected by different acids vary according to the fluid; thus, the addition of "alumina" to bovine amniotic fluid produced a few, fine precipitations, whereas the allantoic fluid was precipitated like urine. By such means Needham was able to demonstrate, however crudely, that there are considerable differences in the ...

... modern artists; the blue was either cobalt or oxide of copper; the white was oxide of tin.

... also for this purpose. "Filaments of carbon placed in a combustion tube with a little chloride ammonium. Chloride tungsten or titanium passed through hot tube, depositing a film of metal on the carbon; or filaments of zirconia oxide, or alumina or magnesia, thoria or other infusible oxides mixed or separate, and obtained by moistening and squirting through a die, are thus coated with above metals and used for incandescent lamps. Osmium from a volatile compound of same ...

... ferruginous or brick-dust colour, sometimes deepened into dark red. Apparently the special character which distinguishes laterite from other forms of red-coloured weathering is the presence of hydrous oxide of alumina in varying proportions. . . . 'Though there is still a great deal of uncertainty about the way in which laterite was formed, the facts which are known of its distribution seem to show that it is a distinct form of weathering, which is confined to low ...

... Another gramme was also taken, without picking out the metallic iron, and was tested for chlorine and for phosphoric acid. The results of the qualitative analysis were that the stone contains silica, magnesia, a little alumina, oxide of iron and nickel, a little tin, an alloy of iron and nickel, phosphoric acid, and a trace of chlorine. These ingredients being determined, the plan for a quantitative analysis was laid out, and was duly executed by the usual and approved methods The following ...
