Letter from A B [Augustus Bozzi] Granville, Grafton Street, to Charles Hatchett, Belle Vue House, Chelsea On his return home from their 'intellectual banquet' he consulted his books to discover the process of making a copper and mercury amalgam as Hatchett described having obtained. He cannot find anything that was not complicated or unscientific and asks for a note from Hatchett to record the method, or a reference to the source. 21 July 1836
