London - Regrets that WW's paper on crystallography cannot now be communicated till the Royal Society's first meeting in November.
London - It was HD's intention to have had WW's paper on crystallography read at the next meeting of the Royal Society, and he was in no doubt it would have been printed by the Council. It is 'an admirable application of mathematical to physical science'. WW should make 'the additions' he alluded to and then 'communicate it' to the Royal Society.
London - John Herschel was late in writing because he was hoping to meet WW and RJ in person. WW just caught him 'as he was going to see Davy [Humphry Davy] make some experiments on galvanism which are odd enough'. WW picked up a copy of Rickman [Thomas Rickman, 'An Attempt to Discriminate the Styles of Architecture in England from the Conquest to the Reformation', 1817] for RJ from Taylor's architectural library in Holborn: 'I think you will find it worth cramming - and for the furtherance of your future theory of the origin of pointed architecture I picked up some views of Peterborough which I found and which will show your favourite Basilica on a large scale'.
HJR poses two optical difficulties: (1). concerning the spokes on a carriage wheel and (2.) an effect involving a candle, plane reflector and a common magnifying glass. HJR has been attending Sir Joseph Banks's evening parties. He has seen a good deal of Charles Babbage: 'Babbage is what Babbage was - but he is acquiring the respect of all the better part of the scientific world by his total absence of all quackery or pretension[.] MacCulloch [John MacCulloch] the geologist is a constant resident nearly in this house and I wish very much you could come and discuss Sir Humphrey Davy with him'. MacCulloch does not think Davy's discoveries are scientific but rather the product of chance. Has WW seen Jeremy Bentham's 'Church of Englandism [Jeremy Bentham, 'Church of Englandism and its Catechism Examined', 1818] It is half suppressed - Such a book - but I cannot in this letter give you an account of it. I believe I shall be introduced to him in a few days'.
