Sends proof sheet on the mathematics of representation. Intends to print in full JH's letter to Mrs. Drummond. Has not yet received information regarding the measuring bars as T. A. Larcom is busy.

Informs JH that his comments against sending a major telescope to India were decisive [see JH's 1866-8-11 & 1866-9-4]; biggest cost impediment was salary of observer.
Supports G. W. Kitchin's request that JH write treatise on inductive logic for benefit of Oxford students.
Appreciates the receipt of volume one of the tenth edition of CL's Principles of Geology.
Maintains that a first class refractor is not needed at Masouri in India [see ES's 1866-9-4]. No special characteristics there justify the great expense of such a project.
Discusses current debate over placement of telescope in India. Discusses various possibilities for telescope.
Clarendon Press plans to publish series on logic. Invites JH to write treatise on inductive logic. Expect letters on this from John Phillips and Bartholomew Price.
Acknowledges receipt by R.A.S. of papers relating to William Herschel's observations of double stars.
Requests JH's views on inductive logic for a publication by Cambridge.
In response to ES's 1866-12-6, JH sees no benefit in a great equatorial telescope in India being an itinerant instrument.
Needs time to consider GK's request. What connection is expected between [Clarendon] Press and each author, or among all authors in GK's proposed series?
On the 'Great Phenomenon' of 13 and 14 Nov. [meteor shower]; JH appears to believe that there is an annular ring of very minute planets circling the sun.
Sends some queries regarding meteor showers.
Sends the last sheet of the Memoir that will be necessary for JH to see. Sheets on the measuring bars are held in abeyance.
Did not mean to say that meteors describe an exact circle round the sun. Comments on the phenomena of meteors.
Thanks JH for his sympathy regarding WS's fall. Describes the meteors he saw from his window on December 4.
Grateful that JH is considering [writing treatise on inductive logic]. Each book in series is independent of other authors. Conveyed JH's request to Bartholomew Price.
Congratulates WS on his recovery. Thanks him for the meteor observations. The evidence points to an 11 rather than a 10 year period [in sunspots?].
Was interested to read in JH's Familiar Lectures the chapter on sensorial vision; has been subject himself to the phenomenon described by JH. Queries one of the statements and would like verification from JH on this point.
Is indebted to JH for a number of scientific memoirs, including the General Catalogue of Nebulae and the tract on Physical Geography, both of which he highly esteems. Sends via the Smithsonian his own pamphlet on the Aurora Borealis.
