Pleased by CD’s letter; his object was to apply CD’s principles to the reform of zoology. When this is done, it is wonderful to see how improved one’s understanding of the Crustacea (Arthropoda) becomes. Cites examples.

Is grateful for his letter and will study the memoirs to which he refers. The Editor would also like a photograph; can JH oblige?
Soliciting articles for People's Magazine.
Concerned about 'Commercial weight' of new standard of weights and measures.
Suspects that discrepancy between old and new commercial weights of Standard Pound may be due to trapped air in new standard. Needs WM's reply soon, so JH may inform India Committee on weights and measures.
Offers advice to president of committee for adoption of uniform system of weights and measures for India.
Please transmit enclosed recommendations by JH to Richard Strachey or other members of committee to establish uniform system of weights and measures for India.
Has nothing of Mendelsohn to send to JW. Has R.S.L. letters, but JH does not want to part with them.
[Last page only] Seeks financial support for exploratory survey of Sinai Peninsula.
Impressed by JH's argument against French metric system. Will forward JH's letter to Richard Strachey or, if Strachey is in Abyssinia, to committee for weights and measures in India.
About some instruments to be taken to India by JH's son John.
Does not know if equipment from R.S.L. reached JH's son John at Southampton [see GS's 1867-11-18].
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.
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.
Writes to acknowledge receipt of letter [see JH's 1864-11-25], but it will take time to work through JH's calculations carefully.
Sends JH a copy of 'Enoch.' Thanks JH for his helpful criticisms.
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.
