Pièce 137 - Letter from George Ticknor

Thanks WW for a copy of his pamphlet showing that all matter is heavy ['Demonstration that All Matter is Heavy', Transactions of the Cambridge Philosophical Society 7, 1841]: 'I think, one of the most curious and acute metaphysical discussions for its length, in any language, going one step further, if I mistake not, than Kant did in a similar direction'. He has had the Lyells [Charles Lyell] staying for a fortnight: 'They are most agreeable people and have left a most agreeable impression wherever they have travelled in the country'. GT encloses a copy of the Geological Survey of the State of Massachusetts.
