Encyclopaedia, of Cyclopaedia, signifies the circle, or chain, which connects the different arts and sciences.

In the present work, we have preferably adopted the term "En-cyclopaedia," for reasons which the philological reader will easily discover. But upon the motives which have induced us to combine this word with the epithet " Domestic," we cannot in this place expatiate; as such an account will appear with more propriety in a future preface.

Many attempts have been made by writers, to reduce the whole circle of the arts and sciences to a systematic order, and exhibit a con-netted view of them, by representing what has emphatically been called "The Tree of Knowledge;" but we confess our disappointment on such occasions, as we never have met with a satisfactory ar-rangement. Nor can it be expected that we should succeed in this arduous attempt, so long as there is no accurate and established meaning attached to the very words, which it Would be indispensably necessary to adopt, in order to distinguish the physical from the metaphysical sciences. The latter, indeed, are, at thisuncriticial period, in a manner exiled from the studies of the inquisitive; though they appear to be so closely cemented to the human mind, that they will Constantly intrude on our attention, engage the faculties of speculation, and absorb the powers of reflection, even when in a manner proscribed, - Conceiving, therefore, that it would be a fruitless Innovation to introduce any new terms in the present state of philosophical nomenclature, we shall content ourselves with Simply enumerating the heads of the. different branches of the arts and sciences.
