Places enlarged and improved, and the neceffary Tables and Schemes fupplied by the Illuftrious Sir ISAAC NEWTON, at that Time Lucafian Profeffor of Mathematics in that Univerfity.

And

THE Reason why this great Man took fo much Care in Correcting and Publishing our Author, was, because he thought him neceffary to be read by his Audience, the Young Gentlemen of Cambridge, while he was delivering Lectures upon the fame Subject from the Lucafian Chair. tho' many Hundreds were then printed at Cambridge, and from that Edition often reprinted abroad; yet by being frequently read in both Univerfities, all the Impreffions were in Time fold off; fo that their Scarcity among the Bookfellers was observed by the Reverend Dr BENTLEY to be a great Detriment to the Young Gentlemen of Cambridge in perfecting their Studies (b).

WHEREUPON this worthy Encourager and Advancer of all Sorts of Literature, importuned the Learned Dr JURIN (as being the fittest Person) to take particular Care of a new Impreffion; and, for the Benefit of the younger Students, to fupply the Defects of Varenius with an Appendix, containing the later Difcoveries and Improvements.

TO Him therefore is owing that correct Edition of Varenius, with an excellent Appendix, printed in the Year 1712. and Dedicated to Dr BENTLEY: which is the Edition from whence the following Tranflation was made (c).

I beg leave to infift the more upon this because the Authority of our Author, back'd with three fuch Great and Learned Men, as Sir ISAAC NEWTON, Dr BENTLEY, and Dr JURIN, will doubtless make an English Edition of this Work more acceptable to an English Reader.

jus ego auctoritati, tanti Viri, & cujus eram beneficiis ornatus maximis, non obtemperare omnino non potui, &c.

(c) Bernhardi Varenii Geographia Generalis, &c. adjecta eft Appendix præ

cipua Recentiorum inventa, ad Geographiam fpeEtantia, continens, a JACOBO JURIN, A. M. Collegii S. Trinitatis Socio, & Schola publica Novocaftrenfis Archididafcalo. Can tabrigiæ 1712, in 8vo.

IT is therefore unneceffary to add any thing farther in Recommendation of the Author; or enter into an Encomium of the Work, fince they have both of them fo well recommeded themselves to the Public already. All that remains is only to indicate what has been farther done in our present English Edition.

AND first, in the Geometrical Part, we have given Demonftrations to several Propofitions, where they were wanting, and in a concife Manner explained feveral tedious Demonftrations; or at least have directed the Reader where he may find them ready demonstrated so that we hope by this Means to incite the Studious to pursue the Mathematical Studies, by giving them certain Specimens of their Excellency.

2. IN the Aftronomical Part, we have ftrengthened our Author's Arguments in Favour of the Copernican Hypothefis; and corrected or illuftrated his Affertions and Propofitions, by others taken from later Authors, or built upon more accurate Obfervations made fince his Time.

3. IN the Philofophical and Phyfical Part, we have rejected the improbable Conjectures of the Antients, and the unwarrantable Suppofitions of Des Cartes, which our Author feems to be fond of: Inftead

Instead whereof, we have (with the learned Dr JURIN) introduced the Newtonian Philofophy to folve the Phænomena, as being much more eligible than the Cartefian, for the Agreeable and Geometrical Manner of it's Conclufions. Wherefore we have frequently made use of this New Philofophy, in the Way of Annotations upon our Author, where he has used that of Des Cartes.

4. IN the Geographical and Hydrographi cal Part, there is often not the leaft Confonance or Similitude between the Latin and modern English Names of feveral Countries, Iflands, Seas, Streights, &c. And very often their Names are changed by later Difcoverers, and their Figures and Situations better difcovered fince our Author's Time. Wherefore, in fuch Cafes, we have taken the Liberty to alter their Names, Situations, and Defcriptions, in order to make them conformable to our latest and best English Maps; deviating as little as poffible from our Author's Senfe; and making use of the fame Words as 'tis likely he would have done, had he writ at the fame Time, and in the fame Language. We have done this to avoid, in fome Measure, Marginal Notes, which muft neceffarily have been inferted to have explained a frict Tranflation; but would have been neither entertaining nor inftruЄtive
