Augustus De Morgan
To:
Sir John Herschel
Date:
[11 May 1856]
Source of text:
RS:HS 6.281
Summary:

Has not heard from him for a long time. Thought that the Government was going to turn the R.A.S. out of Somerset House. There is someone to come to the rescue of Richard Sheepshanks. Has not seen Charles Babbage for many years. Their views are incompatible. C. P. Smyth is off to Teneriffe so now is the time for JH to make suggestions. Has set up a committee to make by-laws.

Glad that JH shows renewed interest in mathematics. Besides HW, JH, Augustus De Morgan, and Mr. Gerard, there appear to be no others interested in researching the differences of the powers of zero. Gave outline of HW's paper at Cambridge Philosophical Society. Plans to revise it according to suggestions from JH and De Morgan.
