AS far as the World is Extensible, so far is every part of it Divisible, that is, Infinitely, 1. Proved, 2, 3, 4, 5. From hence we may learn to conceive justly of the Smallness of the Principles of Bodies, 6. And from what is observable of Compounded Bodies with a Microscope, 7, 8. From hence also we may judge of their Qualities, 9. Particularly in the Magnet, 10. And some other Bodies which Attract, 11. The Principles of Bodies, likewise proved to be Unalterable, both in Consistent Bodies, 12, And in Fluids, 13. And this for great Reason, 14. And were therefore Created such, 15. The same Principles were also Created Regular. Proved by Instances in Fluids, 16, 17, 18, 19, 20. And in Consistents. As in Stones, 21, 22. In Metals, 23. In Salts, 24 to 30. In Snow and Frost, 31 to 35. The greater part of all which have One certain Angle in common, 36. Therefore Regular, and Created such, 37, 38.
THE Composition of Principles is also Regular, 1. As observable in the Substance of several Kinds of Bodies. In Plants, 2. And in Animals. Both the Consistent Parts, 3, 4, 5. And the Fluid, 6. Likewise in the Visible Organism of Bodies. As in Plants, 7. So in Animals. Wherein all the Parts, as well as in Plants, do Originally consist of Fibers, 8. Either Soft, or Hard, or both, 9, 10. By the various Position and Composition of which Two Sorts, all the Parts of an Animal are formed, 11. Cartilages and Bones, 12. Muscles, 13, 14, 15. Membranes and Skins, 16, 17. Glands and Glandulous Parts, 18. Whether Conglobated, 19. Or Conglomerated, 20. The Testicles, 21. The Heart and all Muscular Parts, 22. The Spleen, 23. The Kidneys, 24. The Pancreas, 25. The Brain, 26. The Coats wherein they are all involved, 27, 28. The like Regularity is also seen in their Figures, 29, 30, 31, 32. Some further Remarks of the Labyrinth of the Ear, 33. And the Crystal of the Eye, 34.
THE Use of Things further observable, 1. As appearing everywhere, especially in all the Parts of Plants and Animals, 2. In the manifold Variation of every Part; as for example, of the Skin, 3. The Swim-Bladder, 4. The Crystal of the Eye, 5. The Rock-Bone of the Ear, 6. The Parotides, 7. The Teeth, 8. The Wind-pipe, 9, 10. The Lungs, 11. The Brain, 12. Likewise, in the multifarious Use of each Part; as for example, of the Nose, 13. The Eye, 14, 15. The Tongue, 16. The Hand, 17. The Belly-Muscles, 18. In the Conspiring too of many Parts unto One Use; as for Nutrition, 19. For a Single Act, as the Flight of a Bird, 20. Or but to Talk, 21. Or Laugh, 22. Or for a Single Thought, 23. As also in the Relation of one Part to another, 24. And between Man and other Parts of the Universe, 25. All of them, the Undeniable Effects of a most Perfect Understanding, 26. And of Equal Goodness, 27.
