Send me so manie as you thinke needfull vnto thes obseruations, and in requitall, I will send you store of observations. Send me also one of Galileus bookes if anie yet be come ouer and you can get them. Concerning my doubte in Kepler, you see what it is to bee so far fro you. What troubled me a month you satisfyed in a minute. I have supplied verie fitlie my wante of a spheare, in the desolution of a hogshead, for the hopes therof haue framed me a verie fine one. I pray also at your leasure answere the other pointes of my last letter concerning Vieta, Kepler and your selfe. I have nothinge to presence you in counter, but gratitude with a will in act to be vsefull vnto you and a power in proxima potentia ; wch I will not leaue also till I haue broughte ad actum. If you in the meane time can further it, tell wher in I may doe you seruice, and see how wholie you shall dispose of me. Your most assured and louing friend Tra’uenti the longest day of, 1610. Willm Lower. ~ _Addressed:_ To his espesial good frind Mr. Thomas Hariot Seal of Arms, _(B. M. Add._ 6789.) at Sion neere London. [Tra’venti or Trafenty, near Lower Court, is eight or nine miles south-west of Caermarthen, near the confluence of the rivers Taf and Cywyn.] The writer is fortunately able to throw some light upon these letters of Lower to Hariot. In _the Monatlicbe Correspondenz Vol._ 8, 1803, published by F. X. von Zach at Gotha, pages 47-56, is a most interesting fragment of an original letter inEnglish toHariot. Dr Zach says that he found this letter at Petworth in 1784, and it being without date or signature he confidently assigned its authorship to the Earl of Northumberland, and guessed the date to have been prior to 1619. In his many notes he is in raptures over his discovery, and deplores the misfortune of its breaking off in the most interesting place just as the Earl was about to announce the discovery of the elliptical orbit of the comet of 1607, as reasoned out of Hariot’s observations and the writings of Kepler. This famous letter has been used or copied in many places, particularly in Ersch and Gru-ber’s Algemeine Encyklopadie under Hariot.
