Concerning recent works and discussions connected with longitude.
Has returned to Brest, and found his letter. Is honored to correspond with JH. Further regarding pendulum observations.
Is sending him a paper dealing with the measurement of the arc of the meridian between Greenwich and Paris. Further observations along the coast by Lieut. C. L. Largeteau.
Has just received his letter of 27 June. Further work of Lieut. C. L. Largeteau. Longitude readings at various points.
Concerning Lieut. C. L. Largeteau's recent observations.
Has received copies of reprints from Lyell. Points out errors in a printed paper of his. Has been unwell and very busy of late. Would like to add DB's name to the Optical Glass Committee.
Regarding corrections requested by JH in a printed article. Ill health and overwork applies to him also. Pleased to hear of the work of the Optical Glass Committee. Comments on this.
Notes and comparisons for their recent observations of stars. Was interested in the account of Henry Kater's collimator and hopes it will be adapted for Greenwich.
Would like to borrow the drawing of Josef Fraunhofer's telescope. Has received an account of this telescope from Wilhelm Struve, which he is now translating. Regarding the miscarriage of the Memoirs for Struve.
Is sending a copy of Wilhelm Struve's paper on Josef Fraunhofer's telescope. Regarding F. W. Bessel's formula on longitude. Has copies of J. J. Littrow's paper for him.
Enclosing vouchers relating to the stock, etc. Regarding the interpretation of a letter from F. W. Bessel. The inquiries regarding the Astronomer Royal.
Regarding the travels of a packet of Wilhelm Struve's observations. Please bring F. W. Bessel's letter with him when he comes to the Committee meeting.
Will be pleased to accept his invitation to spend some days at Slough.
Send copies of the errata to Giuseppe Piazzi's catalogue. Cloud ruined his observation of Saturn.
Regarding his own experiments with revolving balls.
Richard Copeland has received such instruments as the Board thought he should have. A mountain barometer seems extravagant for his duties. If JH thinks a camera lucida is necessary, one can be supplied.
News since he left Palermo. Comments on the pamphlet NC recently sent him. Has to inform him that he has been elected an Associate of the Astronomical Society.
Is grateful for being elected an Associate of the Astronomical Society. Compares barometers. Grateful for comments on his pamphlet. News of expedition up Mont Cuccio. Local disputes regarding the results.
Thanks for information on the R.S.L. barometers. Would he purchase various instruments for the new observatory. Notes on star readings.
Let Josef Fraunhofer make WW's whole transit instrument, and mural circle as well. Attests to Fraunhofer's artistry. Germans will soon leave no stars to discover. Wishes someone would import G. F. Reichenbach's meridian circle and use it on F. W. Bessel's plan. Suggests WW order clocks from [Robert] Molyneux or [William] Hardy.
