And how great a variety of Phaenomena the same matter, without the addition of any other, and only several ways dispos’d or contex’d, is able to exhibit, may partly appear by the multitude of differing Engins which by the contrivances of skilful Mechanitians, and the dexterity of expert Workmen, may be made of Iron alone. But in our present case being allow’d to deduce compound Bodies from four very differently qualified sorts of matter, he who shall but consider what you freshly took notice of concerning the new Concretes resulting from the mixture of incorporated Minerals, will scarce doubt but that the four Elements mannag’d by Natures Skill may afford a multitude of differing Compounds.
