Prosecute that passage <in> the account of our Island, where 'tis said that [there is scarse anything more ignominious among <true> [ in pencil, replacing 'our' deleted] philosophers, than out of pride or Vanity to defend a detected Error, because one has once embrac'd it.

Entry 815: Editorial notes:

Entry 830: Editorial notes:

Rr: to defend this Passage of the 17th Essay, tho ['he' deleted] out of respect to Aristotle I am content to examine those opinions ['which he thought' deleted] of his, which tho perhaps Erroneous, are ['prob' deleted] somewhat probable; yet I do not thinke my selfe bound to examine those that are <thought> [ replacing 'made' deleted] probable <for> [ replacing 'by' deleted] nothing else, but because they were his opinions.

For in reference to more subordinate & particular Hypotheses the ['History' deleted] matter of fact is chieffly intended and the discourses but secondarily, as being requisite to <bring in &> connect the Historical things together and make the Discourse more uniform & coherent. But ['in reference' deleted] then these matters of fact, when they are subjoind to Principles & grand observations, are not so much set down for their own sake as ['because they' deleted] to illustrate or confirm those grand & pregnant Truths besides the use they may have of increasing the sylva of Natural History


Entry 835: Editorial notes:

Rr in the same Essay how Quailes are deceived by Quaile pipes and other animals are not able to distinguish between artificial songs & the voices [approximately 4-5 words illegible, illegible, at bottom of page] .

Entry 836: Editorial notes:

Remember there also to pursue the Reprehension of those [who, being more solicitous to pass for good Rhetoricians than good Philosophers, had rather injure a Proposition than forbeare adorning it, and wright a thing opposite to Truths than loose an Antithesis, or add to Truth than be wanting to the fullnesse and roundnesse of a Period, ['Justifying' deleted]

Entry 849: Editorial notes:

Those that have but narrow Principles and are acquainted with but few setts of Experiments are not competent Judges of the various wayes whereby the Nature & Qualitys of things may be investigated. As a chymists will not imagine that a Musitian by his viol ['o' altered from 'a'] or Harpsicon could be able to discover whether a metall were good Gold or no, and yet the experiments of Galileo & Marsennus shew that there is a notable difference between the sound of [altered from '&'] 2 strings that would els be an unison whereof the one is of Gold & the other of Copper <or> [ replacing '&' deleted] some other metall. And so Musitians generally thinke, that the proportion that makes <an eighth> [ replacing '⅛' deleted] or a fifth, must be found by that of the length of the strings struck together, whereas the newly nam'd Author shews that the length of the strings being invaried ['ried' altered from 'aded'] , an ⅛ or <a> ⅕ may be struck on them, by stretching them with weights in duplicate proportion to that which makes <an> ⅛ or <a> ⅕.

Shew in the 16 Ess. That Peripateticks & Chymists judge of the Nature & the operations of bodys, as Apothecarys doe of purging Medicines by the quantity & Prædominancy of the Ingredients only blended together, but the Corpuscularians judge of them as Mechanitians doe of Engins, where according to the size shape &c of the parts & their contrivance or the manner of their being join'd together, divers Engines to the same purpose may be made of differing materialls & the same materialls variously shap'd, siz'd, & put together may, by their Mechanical affections, constitute very differing Engines, & fit for very differing purposes.

When once we are reducd to acknowledge <such> a minuteness as is beyond the discernment of sense (& perhaps too of Imagination) tho we may by argueing infer, that some things may have yet a more admireable minuteness; yet tis bold & difficult, if not rash to take upon us, either to measure or (easily) to stint the degrees of that porvity.

How much some qualitys may depend upon the Mechanical affections of matter, may appeare by this, that thô water be accounted the moistest body in the world, yet when the moistening parts whereof alone water is supposd to consist are by glaciation brought to a state of rest or at least kept from that kind of motion that some call diffluence, they doe not at all moisten the bodys they touch, ['t' deleted] as appears in Ice, which, whilst it continues such has the Nature of a dry body, upon the score of its Mechanical affections, thô it cannot be prov'd that any positively drying Ingredient has been admitted into the water to procure an ['ines' deleted] exciccation.


Entry 1000: Editorial notes:

Shew in the 20th Ess. that to ascribe a distinct faculty to every power of operating in a body & to fancy an occult quality proceeding from a latent forme, whenever ['when' inserted, replacing 'n' deleted] vulgar Philosophers Peripatetic or Chymists can not reduce an <odd> effect or Phænomenon to the same Causes with the rest, is as if a man should fancy in a concaveSpeculum a peculiar faculty by which it reflects the beams of Light /BP 17, fol. 163v/ as becoms a specular body: an other by which it greatens the Image beyond the dimentions of the represented body: an other by which it makes the beams it reflects be Convergent ['Con' inserted, replacing 'come', originally part of 'become', deleted] , and so increases light near their concourse: and an other by which it kindles & burns combustible matter; & besides these an occult quality or faculty, whereby 'tis able to cast the image of a Candle (for instance) to a <considerable> distance from it self into the Aire.

['Remember to prove in the 16 Essay that' deleted] Their ['T' altered from 't'] may <perhaps> be no want <neither> in the Mechanical principles nor of ['the' deleted] knowledge of them, to implicate <in general> the Phenomena of nature ['their recited;' deleted] <but> [ replacing 'that' deleted] we may yet want Mechanical contrivances, to enable us to give large <modells or> patterns of the works of Nature. Archimedes wanted not skill in the Mechanical powers, but yet knew not how to make a watch &c. Nor is it requisite that the king of China ['there mention'd' deleted] should be able in so short a time as the Mech. <Philosophy> [ in Greg hand, replacing 'pH.[?]' deleted] has been well cultivated should know how all kinds of <watches> pumps and windmills &c are contriv'd, tho he might know a watch &c to be not an Animal but an Engine.

Entry 1007: Editorial notes:

['Shew there,' deleted] There ['T' altered from 't'] are those that will never hold their peace, till they have no more to say, and to pass for able men <they> [ replacing 'we' deleted] must meet with Readers that are not so.
