148 MEMOIR OF AUGUSTUS HE MORGAN. 



1842. Moon at. the Cape of Good Hope ? I have got his" book, and I 

 have read it with the greatest delight. 

 J. It's a hoax. 



He. A hoax ! Well, I was so delighted to think it was all 

 true. I told our Ambassador of it yesterday, all that had been 

 seen in the Moon, and his Excellency only laughed at me and 

 said it must be a hoax. 



Depend upon it there are thousands in the condition of this 

 young man. 



Yours very truly, 



A. DE MORGAN. 



To Sir John Herschel. 



Camden Street, Oct. 7, 1844. 



1844 MY DEAR SIR JOHN, A certain man, named Malby, who 



makes and edits globes, has procured the copyright and plates 

 of certain 36-inch globes, on which he means to lay down 

 nebulae, to wit, 



Messier, 



W. Herschel (1786, 1789, 1802), 



Dnnlop (1828), 



J. Herschel (1833) ; 



also double stars, &c., &c. Now it strikes me that if by waiting 

 any reasonable fraction of a revolution of the equinoxes he would 

 have your southern patches to dig into his copper, it would be 

 wisdom in him to wait. Can you tell me within two or three 

 revolutions of the Moon's node when the world is likely to have 

 your work ? 



To tough jobs long periods ought to be applied, both for 

 safety and solemnity. But if you are able to reply that you will 

 be ready in a jiffy, or a crack, or less than no time, or a brace 

 of shakes, or the twinkling of a bedpost, or before you can say 

 Jack Robinson, or even the sum of them, of course he must wait. 



Yours very truly, 



A. DE MORGAN. 



To Sir John Herschel. 



7 Camden Street, October 1844. 



MY DEAR SIR JOHN, I take much interest in Malby's globes. 

 1. Because I am writing a ' Use of the Globes ' for them, of 

 which I send you an old proof to destroy at your leisure.
