Organizational matters regarding paper reports; comments on light from sun's corona [see JH's 1868-11-8].
Organizational matters regarding paper reports; comments on light from sun's corona [see JH's 1868-11-8].
Continues experiments with carbonic acid and electric light [see JT's 1868-11-30], hoping to 'explode' idea that atmosphere's polarization is due to reflection by air particles.
Thanks JH for sending plan for swinging cot to prevent seasickness [see ES's [1868]-11-28] and asks for more information.
Thanks JH for sending plan of swing to counteract seasickness. This will enable his long suffering friend Lady Sullivan to escape hay fever by going to sea but without thereby being beset by seasickness.
Disappointed that Benjamin Disraeli's secretary, Charles Fremantle, was appointed to vacancy left at Mint by death of William H. Barton. Thanks for JH's efforts on CS's behalf.
Continues experiments with carbonic acid and electric light [see JT's 1868-11-30], suggesting possible cause of blue cloud color and eventual whitening of light.
Asks JH where to find further information about a salt road and cliffs mentioned in JH's Physical Geography.
Discusses an experiment, described by JH in JH's Familiar Lectures, involving applying colors to paper. FP finds that his results differ from JH's.
Asks JH to look at a paper on musical scales; comments on a paper by A. Prazmosky on polarization of light from the solar corona.
Sends him a vocabulary of Aboriginal dialects and University calendar. The response to his questionnaire has been very disappointing.
Asks JH to sign [C. P. B.] Walker's certificate for the R.S.L.
Thanks JH for reply to letter questioning color experiment in JH's Familiar Lectures. Will conduct the experiment that JH suggests in the book.
Asks JH to review paper on blue color of sky, polarization of skylight, and polarization of light by cloudy matter.
Has arranged for the last R.A.S.M.N. to be sent to him. Lieut. John Herschel has detected a fourth line in the spectrum of the Nebula in Orion.
Will be sending some Pyretheum roseum and some birdlime with instructions for their use. Wrote a few lines to JH's son.
Thanks for his communication regarding the reported changes in Eta Argus, and also Lieut. John Herschel's letter from Bangalore. These will form a valuable addition to the next R.A.S.M.N.
Announces first volume of Physique sociale will appear soon. Discusses humans and law of nature. Says science is neglected in France.
