§ 38. He next consider'd those Bodies, which have neither Sense, Nutrition nor Growth, such as Stones, Earth, Air, and Flame, which he perceiv'd had all of them Three Dimensions, _viz. Length, Breadth, and Thickness_, and that their differences consisted only in this, that some of them were Colour'd, others not, some were Warm, others Cold, and the like. He observ'd that those Bodies which were Warm, grew Cold, and on the contrary, that those which were Cold grew Warm, He saw that Water was rarified into Vapours, and Vapours again Condens'd into Water; and that such things as were Burn't, were turn'd into Coals, Allies, Flame and Smoak, and if in its Ascent it were intercepted by an Arch of Stone or the like, it thickned there and was like other Gross, Earthly Substances. From whence it appear'd to him that, all things were in Reality, _One_, tho' multiplied and diversified in some certain respects, as the Plants and Animals were.
§ 39. Then considering with himself, what that common thing must be, in which the _Sameness_ of the Animals and Plants did consist he saw that it must be some _Body_, like those Bodies, which had a Threefold Dimension, _viz_, Length, Breadth, and Thickness; and that whether it were Hot or Cold, it was like One of those other Bodies which have neither Sense nor Nutrition, and differ'd from them only in those Operations which arise from the Organical parts of Plants and Animals. And that, in, all likelihood, those Operations were not Essential, but deriv'd from something else. So that if those Operations were to be communicated to those other Bodies, they would be like this. Considering it therefore abstractedly, with regard to its Essence only, as stript of those Operations, which at first sight seem'd to flow from it, he perceiv'd that it was a _Body_, of the same kind, with those other Bodies; upon which Contemplation, it appear'd to him that all Bodies, as well those that had Life, as those that had not, as well those that mov'd, as those that rested in their Natural places were _One_; Only there were some Actions in some of them, which proceeded from their Organical Parts; concerning which Actions he could not yet determine whether they were Essential, or deriv'd from something without. Thus he continu'd, considering nothing but the Nature of Bodies, and by this means he perceiv'd, that whereas at first sight, _Things_ had appear'd to him innumerable and not to be comprehended; _Now,_ he discovered the whole Mass and Bulk of Creatures were in Reality only _One_.
