Darwin Correspondence Project

From Albert Müller   31 March 1866

2. Camden Villas, | Jasmin Grove | Penge SE.

31st. March 1866.

Dear Sir.

Whilst thanking you for your kind note of the 28th.,1 I cannot help observing, that if our time would only devote a tithe of the energy it gives to the description of new species, to observations on the habits of living creatures, we should soon have “more light” on that most puzzling question, whether the theory of the descent from one ancestor can really bear the weight not so much of reasoning, but of facts.— I only hope, we may get more extensive evidence in your intended work, which has my best wishes.—2

Your’s obediently | Albert Müller

Charles Darwin Esqre.


Müller refers to Variation.


Calls for more study of behaviour and less of classification to determine whether descent theory can bear the weight not [only] of reasoning but of fact. Hopes CD’s intended book [Variation] will help.
