the interior sound towards himself. The second sound contains a 

 long steel rod terminated at the extremity between the branches 

 of the cage by a small circular saw, a file, or other instrument, 

 according to circumstances. When the stone is well fixed this 

 rod is pushed against it, and by means of a wheel at its external 

 extremity, and a spring bow is made to revolve in the manner of 

 a drill : immediately the dull sound of the rubbing, or breaking 

 down of the calculus is heard ; and the operation for the time is 

 generally finished by the ejection of the fragments, greater or 

 smaller both in size and number, which, mixed with the urine, or 

 with injected warm water, pass by the urethra, already distended 

 by the large sound. 



This process was practised before the Commissioners of the 

 Academy, January 13, on a man named Gentil, thirty-two years 

 of age. On the 3d of February, the third day of operation, the 

 stone was entirely removed ; there had been scarcely any pain, 

 and the patient always went on foot to M. Civiale's house. A man 

 of the name of Laurent, of Rheims, was the second patient treated; 

 the stone was broken with equal success, and was found to have a 

 white kidney-bean for its nucleus. The third and last example 

 before the commissioners, was a man of the name of Peros, who 

 had a stone as large as a pigeon's egg, its complete destruction 

 was effected by the same means. — Ann. de Chim. xxvi. 96. 



11. Effects of Lightning on the Human Body. — The following is 

 an extract from an account by Dr. Tilesius, of Mulhauzen, given 

 in Schiueigger's Journal. 



Two vehicles were passing along a narrow road embedded in a 

 forest : in the first were two brothers of the name of Teele, one 

 aged thirty-three years, the other twenty-nine ; in the second was 

 ]\1. Teele the nephew, aged twenty years, and M. Decker. The 

 lightning struck successively the first horse, the two brothers, 

 ]\1. Decker, and his companion ; the last did not survive. The 

 horse remained dead on the spot: the skin on the lower part of 

 its belly was torn, the mouth open and the teeth black. 



The lightning passed to the younger Teele by his umbrella, which, 

 with his watch, was thrown twenty-four steps off; the vehicle had 

 a hole made in it six inches in diameter. The body, carried to the 

 nearest village, was put into a warm bath and rubbed; blood 

 flowed from the nose, mouth, and ears, but no signs of life ap- 

 peared. The mouth and nose were black ; the skin and muscles 

 of the arms and hands, both of which held the umbrella, were 

 furrowed to the bone ; the sleeves of his clothes were torn ; the 

 lesions of the skin were not like those produced in burns ; the 

 skin appeared as if it had been raised by rapid rubbing, and the 

 clothes bore no trace of burning but seemed as if torn by a sharp 

 point. M. Decker, who was in the same car, received at the same 

 moment, a blow on the stomach so violent that he was thrown
