about parabolicall draughts. If you please you may now 

 keep a week or more before the press, but I shall undertake 

 that it shall attend your leisure. I do not find I have order 

 in your last to proceed to the xxix. probl : and therefore hope 

 to see your directions. I fear you give yourselfe the trouble 

 to copy verbatim what you send me. I conceiv you might 

 adventure to send me your only accurate draughts, and ease 

 yourselfe of that labour, keeping the notions by you possibly 

 in some other method. Begging your pardon and continu- 

 ance of undeserved favours, I commit you to God's care and 

 protection. 



Yours ever to honour and serve you,

 you had received mine, but to this morning I have not re- 

 ceived any, which makes me doubt that you have not received 

 mine, or else that you doubted the truth, or that it was not 

 of any worth. If it came not to your hand, pray be pleased 

 by a few lines to give me notice and I shall give you (if you
