Has been experimenting with photographic papers. Outlines some of his experiments. Has prepared some papers for sale.
Is grateful for his letter. Sends some of his photographic sheets. Now uses a different chemical to prepare his papers. Will be pleased to send JH his results and to receive a copy of the memoir in due course.
Thanks for JH's letter and for the references to meteors. The Austrian observations are important. Gives news of American observers and their work.
Thanks for his letter. His barometer is not intended as a mountain one. Though a slight error does appear now and then it is no worse than other barometers, excepting that at the R.S.L. Would like JH to communicate the drawing and description to the R.S.L.
Is applying for the position of Radcliffe Observer in the place of S. J. Rigaud and would like to use JH's opinion of MJ's star catalogue he used at the Cape.
Was grateful for JH's communication and is pleased his catalogue met JH's approval.
The belladonna JH gave him is throwing up vigorous leaves. Has a scheme for making it leaf and flower in the same season. Has some ingenious machines to show JH when he calls, which may be useful to JH.
Whewell and RJ plan to visit South Wales and would like to stop at Slough en route.
Will be leaving London on 16 July and would like to meet JH at some convenient time to carry out H. C. Oersted's commission.
Sending magnetic observations. Would like a description of A. F. Osler's Anemometer. Regarding the periodical return of the magnetic disturbances on 18 Oct.
Thanks for the gift of the meteorite to the British Museum; an official letter of thanks will follow later.
Too ill to attend a demonstration by CW of one of CW's instruments [?].
Is greatly obliged for the present of flowers. Has introduced another Herschellia into the world as he has used the name for a Disa.
Will be pleased to examine the dried plants. Send them to the Horticultural Society's Garden, Turnham Green.
Has opened the box of dried specimens, but they are unsuitable for his purpose as they are not flat. Suggests that King's College or University College may be a more suitable home for them.
Is working on horticultural considerations of Cape plants and would welcome information on the temperature just below the surface of the soil in relation to the temperature of the air.
Was pleased to hear of the success of JH's exertions. Comments on the instruments required. Thanks for his communication on the copper ring; will try it with the bifilar. W. H. F. Talbot talks of applying the photographic method to meteorological and magnetical instruments. Encloses a paper.
Has ordered the instruments for the Van Diemen's Land observatory. Is uncertain regarding the third magnetometer; T. C. Robinson's has not yet been tested. Will order a dip circle from Paris.
Has just had a letter from C. F. Gauss regarding the hours for observations; comments on this.
