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].
Attached letter from Edward Sabine [see Sabine's 1847-4-7] will allow RH to communicate directly with Sabine.
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.
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.
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.
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.
Skeptical over plan for galvanic illumination of wires. Has not yet seen J. B. Biot article; states he has always held Biot in high regard. Discusses naming of new planet.
Sends angular results from various astronomers using similar epoches.
Will be pleased to accept his offer of the glass wedges. Bad weather has upset his observations. Gives some of his recent observations. James Challis doubts the existence of a ring round Neptune. Is not impressed by Capt. W. S. Jacob's observations.
Are preparing an objective for JH, which they expect to send in August.
Asks JG to allow JH to join the Philosophical Club [see JG's 1847-4-17] on a trial basis for a year or two.

Will forward JH's note. Is pleased he will be joining the new club. Wishes him happiness in his retirement.
Would like some suggestions for books to be awarded for the Maths prize at Eton.
Asks time and place of next meeting of Philosophical Club, having received invitation lacking that information.
Announces next meeting of Philosophical Club.
Sends some new theorems concerning undisturbed parabolic motion; believes that much remains to be discovered in this field.
Returning the sheets of JH's Cape Results together with a list of errors he has noted. Regarding further reading of star Antares. Thanks for the glass wedges. Hopes weather will improve for JH's journey.
