CORRESPONDENCE, 1856-66. ,335 



English, and 'uttering ' one's own coin is a felony. We cannot 1865. 

 say ' somehow or otherically.' 



Yours sincerely,

To Sir J. F. W. Herschel 



91 Adelaide Road, September 27, 1866. 



MY DEAR SIR JOHN, I write without much purpose, unless a 1866. 

 funny fact be one. Ulugh Bey is the end of the chain. An 

 Arabic dictionary maker came to talk to me about getting his 

 names of the stars in Arabic ; thence came various Turks, thence 

 Turkish pupils he had had whom I had had also ; thence 

 Ameen Bey, whose father was Hassein Effendi, who trisected 

 the angle, and who was taught by Ingliz Selim Effendi, who 

 translated ' Bonnycastle.' This Englishman who translated B. 

 must have been Richard Baily, Francis B.'s brother. He 

 certainly ran away and turned Turk, and both F. B. and 

 Miss B. told me that he translated Bonnycastle. Do you 

 happen to remember anything about him ? I remember that 

 Miss B. had his picture. 



I hope you have fought the weather with needle-gun success. 

 By the way, where is it set forth that a leech is a famous 

 barometer, by indications to be seen in his behaviour in the 

 water ? 



I have been looking at the writing of South about Babbage 

 and Davy. There is an exceeding patness of recollection about 

 him on this occasion as on former ones. Are we really to 

 believe that when he called on Sir H. Davy, and wrote a note 

 which he left in Davy's study, he took a copy of that note, so as 

 to be able to give it in complete form ? Or has he done what 

 Thucydides must be held to have done about the speeches of 

 his generals made them as they might have been and ought to 

 have been ? 



What is the real origin of the severance between South and 

 Babbage ? In all Babbage's ' Autobiography ' I cannot find a 

 hint of South' s existence ! 



Do you possess Hyde's edition of Ulugh Bey's ' Catalogue ' 

 (in Arabic and Latin) ? If so, I wish you would lend it to me. 

 I should not wonder if it were in your patrimony, though I 

 should hardly think you would have wanted it yourself. 



With kind regards to Lady Herschel and all around you, 



Yours sincerely, 



A. DE MORGAN.
