To William Horsfall 8 February 1882
Summary
Does not feel that the occurrence of perfect trilobites in the oldest known fossil-bearing rocks is fatal to evolution, as he does not believe these rocks to be contemporaneous with the first appearance of life.
Locomotive spores of some algae are like animals.
