Few indeed are illustrious enough to claim such privileges as these. Those who alter names, often for the worse, according to arbitrary rules of their own, or in order to aim at consequence which they cannot otherwise attain, are best treated with silent neglect. The system should not be encumbered with such names, even as synonyms.

When, however, solid discoveries and improvements are made in the science; when species or genera have been confounded by Linnæus himself, and new ones require to be separated from them, the latter must necessarily receive appropriate appellations; as also when a totally wrong and absurd name has by mistake been given, as Begonia capensis; in such cases names must give place to things, and alterations proceeding from such causes must be submitted to. Thus I believe Mr. Salisbury's Castalia is well separated from Nymphæa. See Annals of Botany, v. 2. 71.
