The importance of correctness and uniformity, in the several impressions of a book of such general use, has suggested the propriety of adopting effectual measures to insure the desirable objects; and it is believed that such measures are taken, as will render all future impressions of this work, uniform in the pages, as well executed and perfectly correct. In the progress of society and improvement, some gradual changes must be expected in a living language; the corresponding alterations in elementary books of instruction, become indispensable; but it is desirable that these alterations should be as few as possible, for they occasion uncertainty and inconvenience. And although perfect uniformity in speaking not probably attainable in any living language, yet it is to be wished, that the youth of our country may be, as little as possible, perplexed with various different systems and standards. Whatever may be the difference of opinion, among individuals, respecting a few particular words, or the particular arrangement of a few classes of words, the general interest of education requires, that a disposition to multiply books and systems of teaching the language of the country, should not be indulged in to an unlimited extent. On this disposition, however, the public sentiment alone can impose restraint.
