Summary

Asks for a testimonial for Edward Newman.

Discusses the Origin, considers natural selection works well when applied to the evolution of nations and groups of men; on the other hand feels the classification of mineral elements is a damaging analogy as it parallels organic classification but could not be derived by any evolutionary means.

Summary

Thanks CD for his letter about GM’s review of the Origin.

Sends instances of correlative organisation and functions which he finds difficult to believe could have accumulated by gradual modifications.
