PREFACE.

The Family Encyclopedia of Useful Knowledge and General Literature, was commenced with the year 1832; and, the publication of it, having been continued in monthly parts, agreeably to the Prospectus, is now brought to a close. Having thus completed an engagement with the public, the compiler avails himself of the opportunity now offered of making a respectful acknowledgement for the patronage received. The commendations bestowed, by Editors and others, on this enterprise, have been truly gratifying to his feelings. He would not be insensible to such indications of an approving community. To merit them is his highest ambition.

Although the first edition of the Family Encyclopedia has been published, as a periodical, in numbers of an uniform size, still it has been the intention of the compiler, to give it a character fitting it for standing use. Accordingly, it has been stereotyped, and will hereafter be furnished to the public in successive editions, as they shall be needed. A multitude of facts, pertaining to general literature, both interesting and useful, is here embodied in a cheap and convenient form, which could scarcely be found, except in larger Encyclopedias, till thus collected together. It is believed that most persons may accustom themselves to make this volume a source of amusement and instruction in their leisure hours. Let them open it where they will, they will probably be obliged to turn over but a few leaves, before they will meet an article that will catch the attention, and amply repay them for the time devoted to its perusal.

Boston, December, 1833.
