Has been absent from home, which accounts for his belated reply. Comments on JH's difficulties in relation to W. H. Hopkins's memoir on the external temperature of the earth. JH's son is progressing well.

JH's letter of resignation was read at a full meeting of the [R.S.L.] club last evening and it was the unanimous wish of those present that JH should not resign.

Is glad he likes the idea of projecting more than a hemisphere. Compares his own projection and a stereoscopic projection and comments on the results. Is now having another projection made that should give an accurate map of America.

Thanks for his letter and projection. Compares it with one of his own devising and encloses a chart of the isothermal lines of the Northern hemisphere. Has used a different system for his Cape Results.

Is grateful for his valuable remarks on the various projections of the sphere. Thinks the projection devised by JH to be well suited for isothermal lines. Has constructed a chart of the polar regions for the same purpose. Will try JH's projection.

Thanks JJ for the counterfeit coin he sent; JH comments on the possibility of oval coinage.

Is willing to have his review sent on to the author, [C. P.] Smyth; asks GS to send the R.S.L.'s copy of Keith Johnson's Physical Atlas to JH.

Was indebted to JH for the names of the satellites of Uranus. Will find details of his observations in the R.A.S.M.N. Gives volumes. Is thinking of returning to Malta and erect a larger telescope.

Wishes all success to his proposed visit to Malta. Has been able to find the volumes of R.A.S.M.N. Comments on WL's system of levers for his telescope.

Thanks for his suggestions respecting the mode of observation by collimator; will give it careful consideration. Sends two photographs of the method of mounting his observation tower.

Comments on a number of resolutions of the R.S.L., as always encouraging keeping government activity at a distance.

At the last meeting of the B.A.A.S. a resolution was adopted calling for the continuance of the Magnetical Observations. Would work through the joint R.S.L. and R.A.S. committees as before. Would JH agree to continue as chairman? Let him know at the Athenaeum where he returns in a few days.

Does not quite understand JH's note; can he clarify the reading he requires? Comments on his readings on thunderstorms.

Regrets that he cannot attend B.A.A.S. meeting and stay with HL; thanks HL for his paper on the undulating theory.

Is preparing a new edition of Outlines Astr., and would like to know from WL the status of each of the satellites of Uranus and Neptune.

Begs not to be chairman of the proposed Magnetic Conference Committee [see HL's 1857-10-19], but would serve on the committee.

Has received the letter and invitation. Will travel to Etchingham station and walk to Collingwood.

Would like to dedicate to JH a book on climatology that AM is preparing.

Letter accompanying AM's book on climatology.
