    ihead, to say, that Fourcroy, Vauquelin, •and Le Grange, as well as numerous other .able experimentalists, have resolved the cal- kculus into those principles which Hales had ibefore assigned to it. The oil, he observed, was in less quantity, compared to the whole 'substance, than was proportionably contain- ed in the blood and solid parts of animals. The famous Lister, however, in the presence i of the Royal Society, extracted from the j earthy portion of a human calculus, some i iron, by means of a loadstone! Scheele and ilBergman bestowed much attention upon hthe variety of colour and density of stones, i The difference of the latter was not found :to be much. The specific gravity of urinary and biliary concretions differs very much 5 some of the latter being light enough to ; swim on water at first applying them to its j'surface, though they soon sink to the bot- iitom. For the most part, the specific weight ; of the calculus to water is found to be as 11 five to four: Yet Antonius Vander-Linden had a denser stone in his possession, which he ].affirmed to have taken himself out of a dead ! man's body, which weighed thirty-two pounces; and which, for its extraordinary ; size, figure, and quality, he shewed to numbers of the faculty. It was hard, com- i pact, nearly triangular, and of the colour ! of flint; and, as he declared, would strike : fire with a steel. With respect to the tri- : angular figure of this huge calculus, there S can be no doubt but that if it had been
