Prepared to think world infinitely old, but not that life originated with a single cell. Questions whether geological evidence supports gradual progress in organisation. HW thought scientific opinion during Vestiges debate was against this hypothesis. Argues that presence of same senses in lower animals and vertebrates does not imply descent; assumes resemblance is due to living in same world and thus having organs for the same purposes. Wants CD to know how others may see these questions.
