Mr. T. S. Davies on Geometry and Geometers. 387 



is sufficiently minute, as I have not omitted to mark even what 

 are most obviously the blunders of transcription. I did not, 

 however, think it necessary to set down where words were 

 differently divided from what they are in the printed text, 

 and which in many instances occurs in No, 9 without any 

 reason, and I gave up any attention to accents in that MS.; 

 indeed you may remember what Wallis says, ' accentuum 

 spirituumque notae et interstinctionum puncta desiderantur fere 

 omnia.' He certainly studied these MSS. with great atten- 

 tion ; but still I cannot feel perfectly satisfied with his conjec- 

 ture of the one being only a copy of the other. Readings 

 and omissions likewise will be found in each which do not 

 occur in the other; and though there are very many instances 

 of peculiar similarity in them, this may have been occasioned 

 by their both being transcripts from the same original. 



"Pray remember me to my old acquaintance Mr. Dalby, 

 whom by some strange oversight I neglected to mention in 

 my last letter. " Your most humble Servant, 



" Oxford, Feb. 24, 1816." " S. P. RiGAUD." 



" P.S. You omitted to mention the bookseller who receives 

 the subscription for the Diaries. I shall go to the publisher 

 if I hear nothing from you to the contrary ; and I should not 

 have troubled you on the subject, if I had not been afraid of 

 a mistake between your copies (for one of which I consider 

 myself as subscribing) and those which remained as Mr. Maw- 

 man's property."
