Item 111 - Letter from Augustus De Morgan

7 Camden St. & Town - WW's practice of keeping letters will rank next to George Airy 'for extreme method', which he caricatures. Discusses his dispute with Sir William Hamilton, who is recovering from illness and will be treated with consideration; describes what he did when he realised their conclusions were similar. Is glad Whewell's recollection of the meeting is the same as De Morgan's, and will have a meeting with Charles Babbage privately about it.
