Comments on the reports of the birthday celebrations for JH's aunt Caroline.
Comments on the reports of the birthday celebrations for JH's aunt Caroline.
Presents 'tables for facilitating the approximate prediction of occultation and eclipses for any particular place,' so that seamen without specialized backgrounds in mathematics can observe and improve hydrography.
Sends some results concerning undisturbed parabolic motion. Laments the Irish famine.
Is very grateful for his assistance and encloses the page of the report in which he publicly acknowledges this. Further results since the return of the great atmospheric wave of 1845.
Sending a series of magnetical and meteorological observations made at the observatory. Comments on these.
Returns WB's proofs. Compliments WB's successes in meteorology. Barometric waves may be caused by something 'complementary' in opposite seasons or hemispheres.
Has signed the certificate, and stated that FG is known to him.
If given precise instructions, will attempt to obtain the prismatic spectra from Toronto and St. Helena that [Robert] Hunt requested [see Hunt's 1847-3-3].
Descriptions of the algae specimens found on the Beagle voyage.
JDH’s proposed India trip.
Will sorely miss discussions with JDH on species theory.
CD is getting on wretchedly with cirripedes.
Attached letter from Edward Sabine [see Sabine's 1847-4-7] will allow RH to communicate directly with Sabine.
Will send village carrier for volumes [of the Trans. Agric. & Hortic. Soc. India].
[Copy made by CD’s amanuensis.] Discusses the rarity of intermediate forms.
Is reading JH's book and marvelling at the condensed amount of information it contains. Has been observing some of Wilhelm Struve's more difficult objects. Regarding the double star Antares. Has been testing his telescope for errors and found it accurate.
CD understands that JFR cannot lend him the volumes [of Trans. Agric. & Hortic. Soc. India] at present. Thanks for offer to inform him of other works on the breeds of animals in India.
CD fears his belonging to the new club [Philosophical Club of the Royal Society] would be useless, since he is seldom able to dine out.
Meeting for the formation of a new club took place last Monday. Gives list of persons who attended. To be called the Philosophical Club. Outlines its rules and regulations.
Admires RP’s volume [Introduction to zoology, pt 1 (1846)]; he has condensed a great deal of accurate information. CD hopes some good naturalists will spring up as a result.
Studies two possible orbits of Gamma Virginis; sends complete descriptions of both, including calculation of the apparent and actual ellipse. The first orbit combines the data of other astronomers.
Thanks for H. C. Watson’s interesting letter. Disagrees with him on intermediate varieties.
CD has read latest numbers of JDH’s The botany of the Antarctic voyage [pt I, Flora Antarctica (1844–7)]; notes several sentences against "us Transmutationists".
On WH's 'Hodograph' and theorems of parabolic motion and the relation between velocities, initial velocities, and time. Praises WH's son. Cape Results nearly finished. Revising book on astronomy. Plans to 'attack' quaternions. Mentions parabolic functions and Benjamin Peirce's claim that the discovery of Neptune was accidental.
