For not only must variety of knowledge have led to copiousness of expression, but the most cultivated minds would naturally be most apt to observe what was orderly in the use of speech.

A language, indeed, after its proper form is well fixed by letters, must resist all introduction of foreign idioms, or become corrupted.

Hence it is, that Dr.
Johnson avers, "The great pest of speech is frequency of translation.

No book was ever turned from one language into another, without imparting something of its native idiom; this is the most mischievous and comprehensive innovation."-- _Preface to Joh.

Dict._, 4to, p.14.
