    the action of a battery of one hundred and twenty pairs. In twelve hours, it had lost twelve grains. In sixteen hours longer, the mass became so friable as to be broken up, by the slightest pressure, into small crystalline grains. These experimenters then introduced two insulated conductors through the ure- thra of a dog, into the bladder. The dog discovered no uneasiness, while the bladder was distended with warm water, and a pile of one hundred and thirty-five pairs was connected with the conductors. A calculus attached to two conductors, was subsequently intro- duced into the bladder of a bitch, and connected, at various times, with a powerful battery. On being withdrawn, it had lost in weight, and become friable, as, before. The animal, killed a few days after, showed the bladder in a perfectly healthy state. Calculi of uric acid are spoken of as probably an ex- ception to this mode of treatment. MM. Prevost and Dumas propose the introduction of two conductors, by means of a sound, into the bladder, so arranged that by a spring the extremities may be made to spread and embrace the calculus. 303. Strangulated Hernia, and Invagination.— MM. Emery, Cloquet, and Dubois, to whom the sub- ject had been referred, reported, in the session of the French Academy of the 25th of May, 1826,* that the passage of galvanism from twenty-five pairs from the mouth to the anus produced contractions and undula- tions of such a character, in the intestines of animals,
