Orthography.

The proper spelling of words. In the present work all various spellings are treated as synonyms. Some difficulty will always be found in trans-literating proper names from foreign languages; modes of spelling fluctuate rapidly, becoming in general a mere matter of habit or fashion. It would be impossible to ignore the long-established usage in such words as Mongol and Tartar; but an attempt has been made to give the most recent forms in addition.
