Kepler I read diligentlie. but therein I find what it is to be so far from you. For as himfelf, he hath almoft put me out of my wits, his Aequanes, his sections of excentricities, librations in the diameters of Epicycles, revolutions in ellipses, have fo thoroughlie seased upon my imagination as I do not onlie ever dreame of them, but oftentimes awake lose my selfe, and power of thinkinge with to much wantinge to it. not of his caufes for I cannot phansie those magnetical natures, but aboute his theorie which me thinks (although I cannot yet overmafter manie of his particulars) he eftablifheth soundlie and as you say overthrowes the circular Aftronomie. Do you not here startle, to see every day some of your inventions taken from you ; for I remember long since you told me as much, that the motions of the planets were not perfect circles. So you taught me the curious way to observe weight in Water, and within a while after Ghetaldi comes out with it in print, a little before Vieta prevented [anticipated] you of the gharland of the greate Invention of Algebra, al these were your deues and manie others that I could mention ; and yet to great reservednesse had robd you of these glories, but although the inventions be greate, the first and last I meane, yet when I survei your storehouse, I see they are the smallest things and such as in comparison of manie others are of smal or no value. Onlie let this remember you, that it is possible by to much procrastination to be prevented in the honor of some of your rarest inventions and speculations. Let your Countrie and frinds injoye the comforts they would have in the true and greate honor you would purchase your selfe by publishing some of your choise workes, but you know best what you have to doe. Onlie I, because I wish you all good, with this, and sometimes the more longinglie, because in one of your letters you gave me some kind of hope therof. But againe to Kepler I have read him twice over cursoridlie. I read him now with Calculation. Some times I find a difference of minutes, sometimes false prints, and sometimes an utter confufion in his accounts, these difficulties are so manie, and often as here againe I want your conference, for I know an hower with you, would advance my studies more than a yeare heare, to give you a taft of some of thes difficulties that you may judge of my capacitie, I will send you onlie this one [upon the _Locum Martis_ out of Kepler’s Astronomy, de motibus Stella: Martis, etc. Pragæ, 1609, folio Ch. xxvi, page 137.] For this theorie I am much in love with these particulars; 1° his permutation of the medial to the apparent motions, for it is more rational that all dimensions as of Eccentricities, apogacies, etc.. . . should depend rather of the habitude to the sun, then to the imaginarie circle of orbis annuus.
