Transcription

[fol. 307] Honoured Sr I must entreat you to putt into your Coach tomorrow Michel Mastlin’s Observations of the Comet of 1580, which I want to compare with Tycho Brahe’s Observations of the same, which were putt the other day into my hands by the Society. I know you have the book, for I formerly borrowed it of you, and made an extract thereof, which having mislaid is at present lost to me. If you please to favour me in this matter you will lay a new obligation on your most faithfull and Obedient servant Edmond Halley Greenwich Novemb 7 1722

Edmond Halley left Oxford without an undergraduate degree to travel the world, giving him the opportunity to study astronomy on the spot. Upon returning to England he had a prestigious career and collaborated with Sir Isaac Newton, entered the public service, served as a professor at Oxford, and was appointed Astronomer Royal in 1721 (Alan Cook, “Halley, Edmond (1656-1742)”, Oxford Dictionary of National Biography, Oxford University Press, 2004; online edn, May 2009 [http://www.oxforddnb.com/view/article/12011, accessed 1 June 2011]).
