LITERATURE OF COLUMBIUM

1801-1887.

PREFACE.

The following "Index to the Literature of Columbium" has been pub- lished upon the recommendation of the Committee on Indexing Chemical

Literature, of the American Association for the Advancement of Science. " " " In its original draft the word was used in place of columbium ; but upon suggestion from members of the Committee the author consented to a change. It is well known that the name columbium, originally given by Hatchett, has clear priority; while "niobium," and its supposed twin

"pelopium," grew out of errors made by Rose, Although in European treatises the name "niobium" has generally been adopted, no good reason for the substitution has ever been offered, and all the accepted rules of nomenclature demand the retention of columbium. This note has been written at the request of Professor Traphagen. F. W. Clarke.
