Examples from Iliad and other sources to show that military offensive tactic called 'Vertical Fire' did not originate with [L. N. M.] Carnot, as Mr. Mallet claimed in recent issue of Budget.
No permanent optical solution to DS's double vision. Remarks on description by DS's son of cavalry duty in Ireland and Canada.
Inquires about other sunspot observations made by JH.
Asks whether WS has photographs of the sun for 21 and 22 April. Notes how curious sunspot activity has been. Doubts that such is reconcilable with the notion of 'meteoric in-falls.'
Writes to compare notes on sunspot observations.
Comments on the effect of great temperature variations on the speculum of a telescope.
ES has been forwarded letter explaining why 'great telescope' at Melbourne will not work and suggesting construction corrections, on which JH, who believes such 'a priori condemnation' unjustified, comments herein.
Is returning March heliographs. Discusses the appearance of the spots. Has not received the April heliographs.
Wants to compare Mr. Titterton's photographs of the spot groups to [Warren] de La Rue's. Has tried to determine if some localities regularly have spots.
Thanks for the photographs WD sent for the dates requested in JH's 1870-4-23.
Thanks for sending G. A. Erman's two papers on terrestrial magnetism and letter to JH. Will forward these to G. G. Stokes with recommendation that B.A.A.S. continue funding for reduction work of H. J. R. Petersen. Awaits AM's visit to Collingwood.
Forwards letter from G. A. Erman of Berlin requesting that B.A.A.S. fund [H. J. R.] Petersen's study of terrestrial magnetism.
Writes to support grant request from Georg Erman of Berlin to allow Erman to do calculations on magnetism observations from circumnavigation of world.
Thanks RP for sending RP's Other Worlds than Ours and supplies comments, some favorable, on numerous claims made therein, e.g., on RP's theory that Jupiter and Saturn are hot and to some degree luminous.
About a grant to support [H. J. R.] Petersen while he carries out the reduction of terrestrial magnetic observations.
The research shows no particularly 'maculiferous' area on the sun, but WS may, as WS requested, present 'data' to the R.A.S. Has noticed two new spots on helioautographs on 20 and 27 April.
Assures RP that he is not upset at RP for publicly questioning some of JH's ideas. Continues discussion of point in perturbation theory for Uranus.
Giving his opinion on a paper and drawing of [Francis] Abbott.
