 ... to be made of forged steel, and supplied by Elswick. In appearance it very closely resembles those fired from the 100 ton gun at Spezia, but if it is made on the Firmini system, it will differ from it in the composition of its metal, inasmuch as it will contain a large proportion of chromium, probably from 1 to 2 per cent., whereas an analysis of Krupp's shell gives none. In fact, as Krupp's agent at Spezia predicted, the analysis is less instructive than we could ...

For example, at first he represented ferrous and ferric oxides by the formulae FeO2, FeO3, and by the analogy of zinc and other basic oxides he regarded these substances as constituted similarly to FeO2, and the acidic oxides alumina and chromium oxide as similar to FeO3. He found, however, that chromic acid, which he had represented as CrO6, neutralized a base containing 1/3 the quantity of oxygen. He inferred that chromic acid must contain only three atoms of oxygen, as did sulphuric acid SO3; consequently chromic oxide, ...
