From J. D. Hooker [23 September 1873]
Summary
Thanks for C. E. Norton’s address.
Tyndall’s answer [Nature 8 (1873): 399] has surprised and disappointed him;
great trouble in announcing Tyndall’s election as President Elect [of BAAS] yesterday. Tyndall may throw up the Presidency. Spottiswoode and JDH have concocted a letter telling him the facts.
A very poor dull meeting. Comments on papers by W. C. Williamson, Clerk Maxwell, David Ferrier, Burdon Sanderson [Rep. BAAS 43: lxx–xci, 23–32,126–7, 131–3].
Has heard Huxley is back quite well.
