Conclusion against blaming GOD81.
Its Inhabitants; which are either Sensitive or Insensitive.
Concerning the Sensitive, some things are
Common to all the Tribes, particularly these Ten:
I. The five Senses and their Organs; the85.
Eye, an admirable Piece of Mechanism in regard of its
Form, for the most part Spherical, which is best for
The Reception of Objects.
Motion of the Eye90.
Situation in the most commodious part of the Body of every Creature.
Motion, in some Animals,
Every way.
Fixed; and the excellent Provision in that case91.
Size: which is in

Such as live abroad in the Light; larger.
Such as live under ground, less.
Number, in some Animals:
Two94.
More: Together with the wise Provision to prevent double Vision.
Parts; some of which are viewed
Transiently, the Arteries, Veins, and some of the Muscles and Tunicks.
More strictly some of the
Muscles, and the excellent Provision made for their peculiar Uses, Equilibration, &c.96.

Situated in the very best place for Information, Security, and near the Eye and Brain.
The Fabrick of the Outward Ear, which is in
All Creatures formed, guarded, placed, and every way accoutered according to their various Places and Occasion115.
Man suitable to his erect Posture; and all its Parts, the Helix, Tragus, Concha, &c. admirably suited to the Reception and Melioration of Sounds, and the Security of the Part.
Inward Ear: In which I take a View of the121.
Auditory Passage, curiously tunnelled, tortuous and smooth and being always open, is lined with the nauseous Ear-wax for a Guard.
Tuba Eustachiana122.
Bone, particularly hard and context for Guard, and to assist the Sound.
Tympanum, and its Membrane, Muscles, and four little Bones to correspond to all kinds of Sound.
Labyrinth, Semicircular Canals, Cochlea; all made with the utmost Art127.

Object, Sound. Under which I consider,
The Improvements thereof by the Wit of Man129.
Its great Necessity, and excellent Uses132.
Its Pleasure, and the Power of Musick134.

A Guard against noxious Things138.
The spreading of the Olfactory Nerves.
Prodigious Use of it in all, especially some of the Irrationals139.

Nerves, and their Origine, Ramifications and Inosculations.
More particularly the Loco-Motive Act it self, which is
Swift or slow, with Wings, Legs many or few, or none at all, according to the various Occasions and Ways of Animals Lives. As particularly in
Reptiles, whose Food and Habitation is near at hand.
Man and Quadrupeds, whose Occasions require a larger Range, and therefore a swifter Motion164.
Birds, and Insects, whose Food, Habitation and Safety require yet a larger Range, and have accordingly a yet swifter Motion and direct Conveyance.
Geometrically and neatly performed by the nicest Rules.
Well provided for by the
Due Equipoise of the Body165.
Motive Parts being accurately placed with regard to the Center of the Body’s Gravity, and to undergo their due Proportion of Weight and Exercise.

Overstocked by their Increase.
Depopulated by their Death.
Which is effected in
The several Tribes of Animals by a due Proportion in the

Maintaining such large Numbers of all kinds of Animals on the Land, in the Seas, and divers Places too unlikely to afford sufficient Food.
Adjustment of the Quantity of Food to the Number of Devourers, so that
There is not too much, so as to rot, and annoy the World181.
The most useful is most plentiful, and easiest propagatedibid.
Delight which the various Tribes of Animals have to the Varieties of Food, so that what is grateful to one, is nauseous to another: Which is a wise means to cause
All Creatures to be sufficiently supplied.
All sorts of Food to be consumed.
The World to be kept sweet and clean by those means183.
Peculiar Food, that particular Places afford to the Creatures residing therein184.
Curious Apparatus in all Animals for Gathering, and Digestion of their Food, viz. the
Mouth, nicely shaped for Food, &c. In
Some, little and narrow189.
Some, with a large deep Incisure.

Which hath a curious Mechanism of Fibres, Tunicks, Glands, Nerves, Arteries and Veins.
Whose Faculty of Digestion by such seeming weak Menstruums is admirable.
Whose Size and Strength is conformable to the Nature of the Food, or Occasions of Animals.
Which is in
Tame Animals but one.
Ruminants, Birds, &c. more.
Guts, whose Tunicks, Glands, Fibres, Valves, and Peristaltick Motion deserve Admiration201.

VII. The Cloathing of Animals, which is214.
Suited to the Place and Occasions of all. In
Man, it is left to his own Reason and Art, joined with sufficient Materials: Which is best for him,
Because he may sute his Cloathing to his Quality and Business218.
For Perspiration and Health sake.
To exercise his Art and Industry.
To excite his Diligence in keeping himself sweet and clean.
In being the Parent of divers Callings219.
Irrationals: Who are either
Ready furnished with proper Cloathing.
On the dry Land with Hair, Fleeces, Furrs, Shells, hard Skins, &c.220.
In the Air with Feathers, light, strong and warm.

Convenience of their Nests and Habitations for the
Hatching and Education of their Young228.
Guard and Defence of themselves and their Young.
Fabrick of their Nests, scarce imitable by Man, and shewn by their Contrivance and Make, being exactly suitable to their Occasions, and made by
Putting only a few ugly Sticks, Moss, Dirt, &c. together231.
Building Combs according to the best Rules of Mathematicks.
Weaving Webs, and making Cases. For which Service the Parts of their Bodies, and Materials afforded by them are very considerable.
IX. Animals Self-Preservation. For which there is always a Guard in proportion to the Dangers and Occasions of their State. Which is observable in
Man, whose Reason and Art supplies the Defect of Natural Armature.
Irrational Creatures; who
As they are on one Hand sufficiently guarded by their

Compleat Order they observe.
Neat Apparatus their Bodies are provided with for this purpose248.
Natural Venom they inject with their Eggs into Vegetables to pervert Nature, and produce Balls, and Cases250.

Diligence and Concern for their Young, in point of
Incubation253.
Safety and Defence254.
Faculty of Nursing their Young, by
Suckling them. In which it is observable
How suitable this Food is.
How willingly parted with by all, even the most savage.
What a compleat Apparatus in all Creatures of Dugs, &c.
Putting Food in their Mouths, with their proper Parts
for catching and conveying Food255.
Neither way, but by laying in Provisions before-hand256.
Having in the Fourth Book thus dispatched the Decad of Things in common to the Sensitive Creatures, I take a view of their particular Tribes, viz. of
Man; whom I consider with relation to his
Soul. Concerning which having cursorily mentioned divers things, I insist upon two as shewing an especial divine Management, the
Various Genii, or Inclinations of Men, which is a wise Provision for the Dispatch for all the World’s Affairs, and that they may be performed with Pleasure263.
Inventive Faculty, In which it is remarkable that
Its Compass is so large, extending to all things of Use, and occasioning so many several Callings.
Things of greatest Necessity and Use were soon and easily found out; but things less useful later, and dangerous things not yet. Here of divers particular Inventions, with an Exhortation to exercise and improve our Gifts.

Feathers, which are
Most exactly made for Lightness and Strength.
All well placed in every Part, for the Covering and Motion of the Body.
Preened and dressed334.

The Neglect of it in any, as the Ostrich, and the wonderful Provision for the Young in that Case354.
Nidification. Of which before.
