Thanks JDH and Lyell for the actions they have taken with respect to ARW’s and CD’s papers. Considers himself fortunate to have been given any merit for his work. Is pleased that his correspondence has led to the earlier publication of CD’s work. It would have caused him "much pain & regret" if CD had made ARW’s paper public unaccompanied by his own views.

Anticipates that all their differences are fated to find expression in projected book on man.

Offers his early MS with useful references related to the distribution of animals. Hopes ARW’s book will not be "little".

Sends 6th ed. of Origin;

draws attention to his criticism of ARW’s estimate of Kovalevsky;

mentions his disagreement with much of Spencer’s doctrine

and in a postscript points out an inaccuracy in an article in Once a Month.
