The powder obtained in sawing the calculus was found by Dr. Bacon to consist of phosph. of lime, a considerable amount of the triple phosph., and small proportions of carb. of lime, ox. of lime, and animal matter. For a report of the case, with a figure of the calculus, see Med. Jour., Vol. 58. p. 13. 1858. Dr. H. J. Bigelow.
