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.

2° His elliptical iter planetarum. for me thinks it shiews a Way to the folving of the unknown walks of comets.  For ai his Ellipfis in the Earths motion is more a circle [here endeth Dr Zacb’s fragment, and here beginneth the continuation from tie original in the Britith Museum] and in Mars is more longe and in some of the other planets may be longer againe so in thos commets that are appeard fixed the ellipsis may be neere a right line.

3.  His phansie of ecliptica media or his via regia of the sun, vnto wch the walke of al the other planets is obliqj more or lesse; even the ecliptica uera under wch the earth walkes his yeares journie; by wch he solues handsomelie the mutation of the starres latitudes.  Indeed I am much delighted with his booke, but he is so tough in rnanie places as I cannot bite him.  I pray write me some instructions in your next, how I may deale with him to ouermaster him for I am readie to take paines, te modo jura dantem indigeo, dictatorem exposco.  But in his booke I am much out of loue with thes particulars.  I. First his manie and intolerable atechnies, whence deriue thos manie and vncertaine assayes of calculation. 2.  His finding fault with Vieta for mending the like things in Ptol:  Cop..... but se the justice Vieta speakes sleightlie of Copernicus a greater then Atlas.  Kepler speakes as slightlie of Vieta, a greater then Appollonius whom Kepler everie wher admires.  For whosoever can doe the things that Kepler cannot doe, shalbe to him great Appollonius.  But enough of Kepler let me once againe intreate your counsel how to read him with best profit, for I am wholie possessed with Astronomical speculations
