Looking for winter lodgings.
Looking for winter lodgings.
Has taken lodgings at 5 Kensington Square, and now needs introductions to friends of the Herschels in the area [letter completed 1827-10-8].
Her mother has died and she would like him to use his influence at the R.S.L. to raise a subscription for the benefit of her and her brothers and sisters.
Would like to establish himself in England for the purpose of making high quality glass using a process developed by his father [P. L. Guinand].
Tells AG that JH is a member of a committee looking for ways of making better glass, so AG should not reveal any secrets to JH. JH provides the names of the leading telescope-makers in London, whom AG may wish to contact.
Is still looking for suitable people to work in the glass experiments.
Thanks for the works. How can he send some for the R.S.L. and Astronomical Society?
Has just returned from the Alps, where he worked on the glacier at Chamouny and in the St. Bernard. Comments on his work and on the work of the actinometer. Regrets to hear of the death of Mrs. Babbage.
Comments on [Pierrre] Guinand's glass making process. Believes the glass made Guinand's way will be too expensive [see JH's 1827-10-20].
Writes in favour of a London University professorship for Thomas Key. Refers to some optical experiments of Michael Faraday, and extends solution of conic section problem first raised in WT's letter of 1826-2-27.
Thanks JH for letter. Regrets having missed possibility of seeing JH while in England. Asks JH to convince [Charles] Babbage to pass through Brussels instead of Rotterdam.
Thanks for, praises, and comments on WH's 'Systems of Rays' paper. Says WH will have a distinguished career. Mentions other works and hopes to forward them with others he receives to WH.
Sorry that he could not meet JH when JH was in Dublin; hopes to be introduced to JH soon. Answers JH's queries about WH's work; explains that he is studying 'the general properties of systems of rays, and of the surfaces with which they are connected.'
Requesting a copy of JH's paper on 'Object planes.' Encloses with this letter his own paper on 'Eyepieces.' Requesting that Greenwich Observations be sent to the University Library, Cambridge.
His father is ill. Wishes to thank everyone for their kindness to his father on his recent visit to London.
Comments on GA's work on the solar tables, GA's pending paper on eyepieces, and on the quality of observations made at Greenwich and Paris; GA is intending to repeat the experiment of swinging a pendulum in a mine, and JH believes the Board of Longitude can provide the equipment.
Encloses parcel for JH's mother. Mr. Beckwith suffered paralytic attack. SW did not report this to Lady Mary Herschel, but JH may if he deems it wise.
Has been able to destroy a large portion of the color of brown sugar by the use of chlorine. If these hints are of use to TH's friend, TH may convey them.
Hopes to draw up 'a comparative view of the chemical and mineralogical classification of fossils....' Asks JH's view of J. J. Berzelius's system of chemical notation.
Is having some of JH's friends to dinner and would be pleased if he would join them. Affairs of the Geological Society. Has notice from Capt. P. P. King with specimens from the Straits of Magellan.
