Is unable to be of assistance to JH in the matter of a military appointment.

About JG's intended marriage.

Has briefly come into London on distressing business.

Will be pleased to breakfast with him tomorrow, but must leave before ten in order to keep an appointment.

Would like him to accept a small work on the analysis of force.

Would like to see him at dinner tomorrow.

Arrangements for the 12th suits him well, and looks forward to staying with him.

Would be very pleased to spend a day with him before his return.

Further explanation of a matter in gunnery. Can send further sketches if he is still interested.

Has accepted an invitation to visit the Victory and hopes to meet the JH's at the same party. Is off to the dockyard to see about an anchor.

Has been staying at Rome, where the climate did not suit him, but is now on a small ship touring the Mediterranean. Sends a letter of Feliciano Scarpelini, who has a man working a specula made of marble. Palermo Observatory is being put on a secure footing.

Further about the experiments of T. T. Grant. Man presented him with a sealed packet on the subject of the precession of the equinoxes by means of the libration of the moon.

Where can he obtain details of F. W. Bessel's experiments to which JH refers? Comments on experiments with pendulums.

Would like his opinion on one of the experiments of Isaac Newton, described in the Principia. Has this experiment ever been repeated?

Sending a number of W. J. Hooker's Icones in which he will find a figure of the little green orchis. Can find nothing like his Satyrium. Would he send the bulb trowel he left at the Herschels'.

Many thanks for the bulb; succeeded also in digging one up. Has collected a sackload of bulbs from Table Mountain and sends a few orchidae. Hopes the orobanche will not wither. The composite from JH's garden is Zinnia elegans, a Mexican plant.

JH's plant is a Serruria, a very large genus. Is not certain of the name of the little yellow bulb. Working on a glossary of botanical jargon and a Genera of S. African Plants. Hopes he will send him any odd looking plant when he goes out bulbing. Is working on the Compositae at the moment. Alphonse de Candolle has issued a beautiful arrangement of this difficult family.

Further regarding vegetable colors. Advises him to write to Mrs. Griffiths (Torquay) about algae.

Just going on board to bring back Lady Ryan (wife of Sir Edward?) and will then call to see him. The furniture will be landed immediately. Proposes to sail Saturday morning.

Gives an example of lunar observations. Considers this a more accurate measurement than that obtained by the chronometer.
