myne, it represents objects even. I had not discourse enough 

 with him alone to aske him manie quaeres, but douteless he 

 is an excellent man and verie courteous, and I found him free 

 and open in his discourse to me. He saies he can easilie and 

 infalliblie finde the longitude, but he discovers not that in 

 this booke. He saies the satellites of Jupiter are little sunns, 

 and divers other novelties he hath observed, manie of which 

 he will not discover in this booke. I have no more nowe to 

 trouble you with, but to desire that you will thinke of pub- 

 lishing some of your rarities, especiallie in the analitickes. 

 And so wisshing you all happiness, I remaine 



Your assured friend and servant, 



CHARLES CAVENDYSSHE. 

 Wee are nowe going towardes Bruxells. 



SIR CHARLES CAVENDISH TO JOHN PELL. 



[MS. Birch, Brit. Mus. 4278, fol. 149, Orig.] 



Hamburg, Julie 26, 1644. 



Worthie Sir, I give you manie thankes for your letter, 

 which I received yesterdaie, and since things goe not so well 

 in England, I am glad you are so well placed for the present, 

 for I suppose it a place of good means as well as of honor ; 

 yet I hope by the grace of God wee shall one daie meet in 

 England, and live more happilie there than ever wee did. I 

 thinke wee shall remaine a whyle in this towne, and so be 

 deprived of the happiness of your conversation but by letter, 

 which I desire you will be pleased sometimes to afford me at 

 your best leasure. I desire you will doe me the favoure to/"\ 

 send me one of De Cartes his new bookes, De Principiis Phi- ^ 

 losophi&y without anie addition of his olde worckes, except he"" 

 hath either added or altered something in the matter ; I de- 

 sire you will let me knowe the price of it, and howe I maye 

 with most convenience returne monie to you, for I am likelie 

 to trouble you for more bookes. I praye you let me knowe 

 whether Mr. Warner's Analogicks be printed. I hope you 

 proceed in your intended worcke of Analiticks, which if you 

 doe not, I beseech you doe, and finish it with all convenient 

 speed; for I confess I expect not anie absolute worcke in that 

 kinde, but from yourself. I praye let me knowe what new 

 inventions are extant in the mathematicks latelie, if anie. 

 And so wisshing you all happiness, I rest 



Your assured freind to serve you, 



CHARLES CAVENDYSSHE.
