No summary available.
Sends Dallas’ specimen of indexing [for Variation].
Asks CD’s opinion of likelihood of a hybrid of ass and bull, reported in a MS of a journey to Asia Minor he is reading.
Is grateful for his letter and will study the memoirs to which he refers. The Editor would also like a photograph; can JH oblige?
Will send proto-Lamarckian pamphlet [1799] by Charles White, if CD wishes. It has a graduated scale of types from snipe to man.
Dallas’ index [for Variation] well done but rather too full.
A hybrid from an ass and a bull is utterly incredible.
Variation to be published at end of month.
Dimorphism and self-sterility.

Writes to inquire as to the exact definition of the gallon and the pound, and the circumstances under which the appropriate measures would be made.
Believes Michael Faraday's boro-silicate of lead has not been used for telescopes, but JH and others have tried using it for other optical purposes. Describes method for producing veinless flint glass.
Reports two observations on crossing in dogs: the preservation of both pure types in the offspring of a pointer and a setter, and the influence of a first mating with a mongrel on the progeny of a Barbary bitch and a subsequent Barbary male.
Sends corrected title of Variation and report of progress in printing.
WSD is pleased that CD approves his index draft [for Variation]; notes his objection to long list of references under "Dogs" and will try to find a principle for shortening it. He has not indexed all authors’ names; is this practice satisfactory?
Provides JH with best definition that GA has available for the gallon [see JH's 1867-11-3], noting that methods for establishing standards are revised, even if the standards supposedly are not.
Plans for refracting telescope TW is constructing. Diagrams and questions about lens construction.
Feels that he has been quoted out of context, making it appear that JH favors the introduction of the metric system in India. This being not the case, JH then proceeds to show how the British system of measures is related to terrestrial measurements, especially the length of the earth's polar axis. In so doing, JH argues for the greater accuracy in the definition of the British units, as compared to the metric.
