tell him wher the are to be had and what manner of sphere (I
meant with what and how manie circles) wilbe most vsefull for
vs to thes studies. After all this I must needs tell you my
sorrowes. God that gaue him, hath taken from me my onlie sun,
by continual and strange fits of Epelepsie or Apoloxie, when
in apparence, as he was most pleasant and goodlie, he was most
healthie, but amongst other things, I haue learnt of you to
setle and submit my desires to the will of god ; onlie my wife
with more greife beares this affliction, yet now againe she
begins to be comforted. Let me heare fro you and according to
your leasure and frindshippe haue directions in the course of
studie I am in. Aboue al things take care of your health,
keepe correspondence with Kepler and wherinsoeuer you can haue
vse of me, require it with all libertie. Soe I rest ever,

Your assured and true friend to be vsed in

all things that you please.

Willm Lowër.
