82 MEMOIR OF AUGUSTUS DE MORGAN. 



1836. which owns the upper storey, has cat a floor through what was 

 a ntaircase, so that our rooms in part present a section like the fol- 

 lowing. 1 .... However, I suppose it will come right somehow or 

 other. Our meeting-room will hold from ninety to a hundred com- 

 fortably. Our largest meeting hitherto has been eighty. 

 Give my kind regards all round, and believe me, 



Yours sincerely, 



A. DE MORGAN. 

 5 Upper Gower Street. 



To Dean Peacock. 



DEAR SIR, I send you herewith my series, corrected and 

 revised in the newest manner. The result is so much generalised 

 from that in the Calculus of Functions, that I think it may be 

 considered as new matter. 



I send also a small work with a new kind of title, being an 

 endeavour to make the fifth book of Euclid somewhat readable. 

 It is meant to be the first part of a book on Trigonometry. The 

 astronomical world here has been enlightened by a starlight 

 Knight, 2 at the Royal Institute. What Young and Faraday 

 have there said of physics has been completely outdone. I did 

 not hear the lectures, but am told that if I had I should have 

 known how George III., surrounded by his Astronomers, went 

 to Kew to see an occultation, foregoing the stag-hunt which 

 was going on ; how a cloud hid the moon, and how the pious 

 King, without a single murmur against Providence (a point dwelt 

 upon as remarkable), turned the telescope at the hunters, and 

 saw the stag killed, between the two horizontal wires. The second 

 lecture was closed by a description of the unfitness of Mathema- 

 ticians to be practical Astronomers, with the exception of Bessel. 

 Now Sir James would have lectured at Cambridge with half the 

 pains which were taken to get Airy. 



I remain, dear Sir, 



Yours very sincerely, 



A. DE MORGAN. 

 Upper Gower Street, April 25, 1836. 



To Sir J. Herschel 



MY DEAR SIR JOHN, Some months ago, when the Calculus 

 of Functions which I now send you was published, I marked 



1 The reader's imagination will easily supply the omitted sketch 

 from the context.
