Formal note of thanks for TA's paper on ozone.
Thanks for JH's kind comments on TA's paper on ozone.
Was elected yesterday to the Registrarship of London University, and thanks JH for his support.
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.
Comments on the state of JH's health, and on things astronomical and mathematical.
Is glad to hear his account of facts. Always thought he would recover his health. Gives one of his own mathematical formulae. Has no idea how the Decimal Coinage Commission is progressing.
[Form letter] Offers to send Commercium epistolicum J. Collins et aliorum... (1856), by J. B. Biot and Francisque Lefort, a critical edition of works by mathematician John Collins.
HW neglected to state principle from which he derived equation for eliminating differences. Expresses it in formula.
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.
