It having been already intimated ( of Phil. Transact. p. 140. 141.) that divers Philosophers aime, among other things, at the Composing of a good Natural History, to superstruct, in time, a Solid and Useful Philosophy upon; and it being of no slight importance, to be furnisht with pertinent Heads, for the direction of Inquirers; that lately named Benefactour to Experimental Philosophy, has been pleased to communicate, for the ends abovesaid, the following Articles, which (as himself did signifie) belong to one of his Essays of the unpublisht part of the ''Usefulness of Nat. and Experimen. Philosophy''.

But first he premises, that what follows, is design'd only to point at the more General heads of Inquiry, which the proposer ignores not to be Divers of them very comprehensive, in so much, that about some of the Subordinate subjects, perhaps too, not the most fertile, he has drawn up Articles of inquisition about particulars, that take up near as much room, as what is here to be deliver'd of this matter.

The Heads themselves follow;

The things, to be observ'd in such a History, may be variously (and almost at pleasure) divided: As, into Supraterraneous, Terrestrial, and Subterraneous; and otherwise: but we will at present distinguish them into those things, that respect the Heavens, or concern the Air, the Water, or the Earth.

1.To the First sort of Particulars, belong the Longitude and Latitude of the Place (that being of moment in reference to the observations about the Air &c.) and consequently the length of the longest and shortest days and nights, the Climate, parallels &c. what fixt starrs are and what not seen there; What Constellations 'tis said to be subject to? Whereunto may be added other Astrological matters, if they be thought worth mentioning. Rh
