Publisher's Synopsis
Excerpt from An Analysis of a Mineral Substance From North America, Containing a Metal Hitherto Unknown
Subsequent examination, however, convinced Rose (and his conclusions have been confirmed by others who have repeated his experiments), that the two metallic acids Obtained from the Bodenmais columbite were really the original columbic acid of Hatchett, discovered in 1801, and the tantalic acid discovered by Ekeberg in 1802. Instead, however, of calling the first mentioned acid niobic acid, its original name should have been left to it. The result of Rose's researches was in fact simply the demonstration Of the actual difference of columbium and tantalum; for Hatchett's discovery was clear, precise, and well made out, and has never been controverted.
This being a correct summary of the history of the composition of the columbium minerals, it is but right, just, and in accordance with chemical and mineralogical prece dence, that the name given by the discoverer should replace that of niobium, which originated forty-five years later.
