Results of CD’s examination of data subvert JB’s former inferences. Will send abstracts from the data for his paper on colour of hair of single and married women 35 to 45 years old ["On the supposed increasing prevalence of dark hair in England", Anthropol. Rev. 1 (1863): 310–12].

Thanks JH for his positive judgement of his work. Mentions that [François] Moigno could only say that it was anti-religious. Another work on statistics has emerged: Versuch einer Sozialethik, 2nd. vol., by Alexander von Ochingen. In few days leaves for international conference on statistics.

Declares himself CD’s defender; but he is a "teleologist".

Sends CD three more papers.

His research confirms his faith and belief in variability of species.

Accepts JH's objection to his method of measuring stellar diameters. Quotes an argument he had published suggesting the existence of a hierarchy of systems in an infinite universe. Discusses his studies of the relation of proper motions to the sun's motion. Asks JH's permission to publish JH's idea that some nebulae may be 'miniature' of the Milky Way.

Requests permission to print JH's response approving of fixed-telescope system for time-keeping set out in TW's new book on civil time-keeping, How to Keep the Clock Right.
