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.

Excerpt from An Analysis of a Mineral Substance From North America, Containing a Metal Hitherto Unknown
In the course of the last summer, when I was examining and arranging some minerals in the British Museum, I observed a small specimen of a dark-coloured heavy substance, which attracted my attention, on account of some resemblance which it had with the Siberian chromate of iron, on which at that time I was making experiments.
Upon referring to Sir Hans Sloane's catalogue, I found that this specimen was only described as "a very heavy black stone, "with golden streaks," which proved to be yellow mica; and it appeared, that it had been sent, with various specimens of iron ores, to Sir Hans Sloane, by Mr. Winthrop, of Massachu-sets. The name of the mine, or place where it was found, is also noted in the catalogue; the writing however is scarcely legible: it appears to be an Indian name, (Nautneauge;) but I am informed by several American gentlemen, that many of the Indian names (by which certain small districts, hills, &c. were forty or fifty years ago distinguished,) are now totally forgotten, and European names have been adopted in the room of them.
