viz.  Sensible Cold, and a Propension to move downwards; But if heated by the Fire or the Sun, its Coldness was remov’d, but its Propension to move downwards still remain’d:  But afterwards, when it came to be more vehemently heated, it lost its tendency downwards, and mounted upwards; and so it was wholly depriv’d of both those Properties which us’d constantly to proceed from it, and from its Form:  Nor did he know any thing more of its Form, but only that these two Actions proceeded from thence; and when these two ceas’d, the Nature of the Form was alter’d, and the watry Form was remov’d from that Body, since there appear’d in it Actions, which must needs owe their Origin to another Form.  Therefore it must have receiv’d another Form which had not been there before,from which arose those Actions, which never us’d to appear in it whilst it had the other Form.

Sec. 49.  Now he knew that every thing that was produc’d anew, must needs have some Producer.  And from this Contemplation, there arose in his Mind a sort of Impression of the Maker of that Form, tho’ his Notion of him as yet was general and indistinct.  Then he paus’d on the examining of these Forms which he knew before, one by one, and found that they were produc’d anew, and that they must of necessity be beholden to some efficient Cause.  Then he consider’d the Essences of Forms, and found that they were nothing else, but only a Disposition of Body to produce such or such Actions.  For instance, Water, when very much heated, is dispos’d to rise upwards, and that Disposition is its Form.  For there is nothing present in this Motion, but Body, and some things which are observ’d to arise from it, which were not in it before (such as Qualities and Motions) and the Efficients which produce them.  Now the fitness of Body for one Motion rather than another, is its Disposition and Form.  The same he concluded of all other Forms, and it appear’d to him, that those Actions which arose from them, were not in reality owing to them, but to the efficient Cause, who made use of these Forms to produce those Actions which are attributed to them, [i.e, the Forms].  Which Notion of his is exactly the same with what God’s Apostle [Mahomet] says; I am his Hearing by which he hears, and his Seeing by which he sees. And in the Alcoran; You did not kill them, but God kill’d them; when thou threwest the Darts, it was not thou that threwest them, but God.

Sec. 50.  Now, when he had attain’d thus far, so as to have a general and indistinct Motion of this Agent, he had a most earnest Desire to know him distinctly.  And because he had not as yet withdrawn himself from the sensible World, he began to look for this voluntary Agent among sensible Things; nor did he as yet know, whether it was one Agent or many.  Therefore he enquir’d strictly into all such Bodies as he had about him, viz. those which he had been employ’d
