Hamburg, January 10, 1644. 



Worthie Sir, It is so longe since I hearde from you that 

 I doute my letters which I last writ to you, came not to your 

 handes. I sent you inclosed in one of them the answeare 

 which I receaved from Auspurge concerning Reyeta's glass, 

 and allso my desire that you would be pleased to enquire of 

 Reyeta, who I heare is at Antwerp, of what conditions one 

 of his glasses may be had. I suppose some merchant of your 

 acquaintance will doe so much for your sake. I have latelie 

 had some discourse with Doctor Jungius and Mr. Tassius ; 

 douteless they are both verie learned men. I was at Doctor 

 Jungius his house, where he shewed me manie treatises of his 

 owne in manuscript, videlicet, DeLocisPlanis, DeMotuLocali, 

 staticks, hydrostaticks, and some observations of insects. I 

 have as greate an opinion of his abilities as of anie mans. I 

 finde he is not yet minded to print anie thinge, but I hope 

 hereafter he will, and I despaire not in the meane time but 

 he will imparte somewhat to me. I asked Mr. Tassius (as 

 you desired me) his opinion of your refutation of the Dane, 

 who aproves of it, and that you doe it without helpe of the 

 Table of Tangents. I writ in some of my last letters to 

 knowe if Cavalieros worckes and Sethus Calvisius of musick 

 were to be had. Sir, I have no more at this time, but wissh- 

 ing you all happiness remaine 



Your assured friend to serve you, 



CHARLES CAVENDYSSHE.

Hamburg, January |*-L, 1644, 



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

 the $ of this month. I am glad to heare you meane not to 

 trouble your self with Longomon. more than as an appendix 

 to some of your intended worckes, which I confess I longe 

 much to see, whatsoever it be, especiallie if it be of analytycks. 

 I give you also manie thankes for your inquirie of Reieta, and 

 hope shortelie to heare from you whether there be anie hopes 

 to procure one of his best glasses. I am glad he will print
