Professor Ernst H. Haeckel,
Referring to my letter of the 10th inst., I write to know wether this Association may have the pleasure of enrolling your name as an Honorary Associate. It may possibly interest you to hear that Mr Leslie Stephen, Mr Edward Clodd and Dr Stanton Coit are among those who have accepted Honorary Associateship.
