The attractions which tend to preserve the original ar- rangement of bodies presented to each other, are denominated Quiefcent attractions; those which tend to destroy the original,, and to form a new arrangement, are termed Divillent attractions. 21. It is evident, that no new arrangement can take place, un- less the divellent be more powerful than the quiescent attractions. classification of elementary or undecomposed sub- stances. 22.

Although, from their not having been yet decompounded, the muriatic, fluoric, and boracic acids are enumerated here, theirr properties are detailed under the head of acids ; for there is every; analogical reason for believing them to be compounds. In treating of these substances, I shall begin with the firs;; class, on account of the very great influence of caloric on alll chemical actions : but, of the second class, I shall first consider the last order, because they are tangible objects, considerably * The brilliant discoveries lately made by Mr. Davy have shewn, that this- arrangement, and, indeed^ every other synthetic arrangement, of the objects ol chemistry, is incorrect: but it was thought better to retain it, as it is, than to attempt any new arrangeraeut, which svould probably require to be altered in^ .the next edition; and to give, in the preface, a summary and connected view oj; his experiments.
