Has been confined to bed with pleurisy. Davies Gilbert called yesterday and gave startling news of the wonders of James South's new telescope. Can JH inform him of its true capabilities? Gilbert talks of having an object glass of 2" diameter made of Michael Faraday's glass.
Has never seen the fair copy of William Herschel's polishing book. Will be pleased to assist Wilhelm Struve regarding the Standards. Will ask George Everest to call on him and discuss the Indian operations. How did Herschel perfect the adjustment of his object glass? Has been experimenting with the Josef Fraunhofer spots.
Does he want a scale ordered form George Dollond for Wilhelm Struve? Will not be in London when Struve arrives. Has written a paper on the Standards for the R.S.L. and will send JH a copy when printed. Comments on the comparison of Standards.
Sends details of the measurement of Wilhelm Struve's standard. Is pleased that JH has given an invitation to [E. de?] Beaumont, who is anxious to become an astronomer and is about to spend £1,200 on instruments. Wishes that JH appeared in town more often.
Has been prevented from answering his letter earlier by increased illness. If he returns to town he will have pleasure in meeting H. C. Schumacher. Believes the pound must be made of bell metal. Thought JH was on his way to the Cape, but sees his letter was written from Slough.
Obliged for the present of his papers. Will keep them until the catalogue arrives. The improvements in his 20' telescope are interesting; comments on this. Will obtain the troy pound as soon as Parliament meets.
