Sir,

I herewthherewith send you Mr Boyle's new Book of Effluviums, wchwhich he desired me to present to you in his name, wthwith his very affectionat service, and assurance of yethe esteem he hath of yryour vertue and knowledge. I take yethe liberty to Ioyne in thesame pacquet two Copies more of yesamethesame Book, one for Dr Barrow, and yethe other for Dr More; wchwhich he intreats you to send to ymthem from him, if they be now at Cambridge; if not, to keep ymthem in yryour hands, till they shall returne thither.

I receiued lately a letter from MonsrMonsieur Hevelius, and in it the Frontispice and Title of the First part of his Machina Cœlestis, together wthwith an Advaice, that he hat deliver'd severall Copies of this Book to a Master of a Ship bound for London; among wchwhich there is one designed for the University of Cambridge: wchwhich when it shall come to my hands, I shall not faile, God willing, to transmit it to yryour Vice Chancellour, whose name, in the Interim, I desire to know. The Title of the book is,

Iohannis Hevelis Machinæ Cœlestis Pars Prior, Organographiam, sive Instrumentorūum omnium Astronomicorūum, quibus Author hactenus sidera rimatus ac dimensus est, accuratam delineationem et descriptionem, pluribus iconibus, æri incisis, illustratam et exornatam, exhibens: Cum aliis quibusdam tam jucundis quam scitu dignis, ad Mechanicam Opticamque Artem pertinentibus, imprimis de Maximorum laborūum constructione et commodissāam directione; nec non, novâ ac facillimâ Lentes quasvis, ex Sectionibus Conicis, expoliendi ratione.

I haue lately procured an Astronomical Correspondence between SignrSignor Cassini and our Mr Flamsteed, wchwhich I belieue will contribute not a litle to yethe Advancement of Astronomy especially if yethe latter, whom SignrSignor Cassini acknowledges to be an a very accurat Observer, can furnish himself wthwith good Instruments.

The two new Planets about Saturn, lately discovered by Cassini, are now to be very well seen, as I am informed from Paris, where SignrSignor Cassini saith they see you wthwith a Telescope of 21. parisian feet.

I shall be glad to hear, ytthat this pacquet is safe come to yryour hands. I am yryour humble servant

Oldenburg.
