To Albert Müller   28 March [1866]


Writes on slave-making ants; cannot explain why fewer slaves are caught in England than in Switzerland.

From Albert Müller   28 March 1866

From Albert Müller   31 March 1866


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.

From Albert Müller   20 May 1868


Wilson Armistead’s death cut short his work on galls, but Müller is continuing it.

In China only uni-coloured animals are sold for meat, the rest are killed in the litter.
