“ This Book undertakes to deliver a more certain and more genuine Method of curing Feavers and Agues, than has obtained hitherto: And it being premised, First, that a Fever is Natures Engine, she brings into the field, to remove her enemy; or her handmaid, either for evacuating the impurities of the blood, or for reducing it into a New State: Secondly, that the true and genuine cure of this sickness consists in such a tempering of the Commotion of the Blood, that it may neither exceed, nor be too languide: This, I say, being premised by the Author, he informs the Reader ”

“ Representing, I say, an Animal in this manner, and thence inferring, how it may be alter'd for the better or worse by motions or impulses, confessedly Mechanicall, observes, How some are recover'd from swouning fits by pricking; others grow faint and do vomit by the bare motion of a Coach; others fall into a troublesome sickness by the agitation of a Ship, and by the Sea-air (whence they recover by rest, and by going a shore.) ”

“ Secondly, that whoever hath had a Quartan formerly, though many years be pass'd, shall, if he chance to have another, be soon freed from it; and that a Physician knowing that, may confidently predict this.
In the Fourth Section, the Author, in conformity to the Custom of those that write of Feavers, discourses of the Small-pox; and First, examining the cattle of this sickness and its universality, delivers his peculiar opinion of the bloud's endeavouring a Renovation or a New Texture (once at least in a Mans life) and is inclin'd to preferr the same to the received doctrine of its malignity. ”

“ A Method, by which a Glass of a small Plano-convex Sphere may be made to refract the Rayes of light to a Focus of a far greater distance, than is usual. This is proposed by Mr. Hook, in consequence of what was mention'd from him in Numb. 4 pag. 67, of these Transactions.
Prepare (saith he) two Glasses, the one exactly flat on both sides, the other flat on the one side, and convex on the other, of what Sphere you please. Let the flat Glass be a little broader than the other. ”

“ I intend likewise to plant them all, as if they were Currants or Goos-berries, so thick as hedges; whereby one man may gather as many of them, as otherwise, when they are planted in trees at distance, four persons may do.

“ Though he denies not, but that, having the honour and advantage of being a Fellow of the said Society, he inserts at times some of the Particulars that are presented to them; to wit, such as he knows he may mention without offending them, or transgressing their Orders; tending only to administer occasion to others also, to consider and carry them further, or to Observe or Experiment the like, according as the nature of such things may require. ”

“ As to the Latter, he observes, that one of the chief causes, rendring the Cure of Feavers so uncertain and unsuccessful, is, that Practitioners do accommodate their observations, they take from the successful cure of some Feavers in one season of the year, or in some one year, to that of all Feavers in any season, or in any year whatsoever. ”

“ In what space of time the Depuration if nature be not disturbed or hindred in her work, will be perform'd: When Purgatives are to be administred: How that Diarrhea's happen, if the Patient had in the beginning of the Feaver an inclination to vomit, but no vomit was given ”

“ I know I have mention'd to you an easie application of what I, some years since, made publick enough; but not finding it to have been yet made by any other, and being perswaded by Experience, that it maybe extended to other Fœtus's, which this season (the Spring) is time to make provision off, I think the Advertisement will not seem unseasonable to some of our Friends ”
