Note 77 — DISSERTATION III.

"Quem penes arbitrium est, et jus et norma loquendi." Horace.——"Nothing," says Kenrick, "has contributed more to the adulteration of living languages, than the too extensive acceptation of Horace's rule in favor of custom. Custom is undoubtedly the rule of present practice; but there would be no end in following the variations daily introduced by caprice. Alterations may sometimes be useful—may be necessary; but they should be made in a manner conformable to the genius and construction of the language. Modus est in rebus. Extremes in this, as in all other cases, are hurtful. We ought by no means to shut the door against the improvements of our language; but it were well that some criterion were established to distinguish between improvement and innovation."——Rhet. Gram. page 6, Dict.
