the opening held to the cat's mouth. In this manner she breathed an 

 enormous quantity of the gas, and though convulsed by it so as to oc- 

 casion her to spring up and rebound violently, they were unable to 

 kill the animal, until by scattering the antimonial powder around her 

 and sprinkling it with the acid, she was surrounded with an atmos- 

 phere of the gas. This destroyed her in about twelve or fourteen 

 minutes. It would therefore be rendering a service to science and 

 humanity to examine anew the real action of sulphuretted hydro- 

 gen, breathed in variable proportions. — Idem. 



6. Cleansing of Sewers. — In a valuable paper, containing an 

 elaborate description of the method pursued under the direction of 

 a commission of able chemists appointed by the police of Paris, it is 

 stated that the most important advantages were derived from the use 

 of chloride of lime as a counteracting agent. The most efficacious 

 mode of employing it was found to be the scattering of hay through 

 different parts of the sewer, and sprinkling the chloride of lime upon 

 it. It was gradually dissolved in the moisture, and diffused its anti- 

 septic qualities through the atmosphere of the sewer. — Idem. 



7. Chlorine. — Several physicians in Paris have been engaged in 

 the administration of chlorine as a remedy in phthisis. Dr. Cotte- 

 reau has contrived an apparatus, by which, and a small lamp and ther- 

 mometer which accompany it, the patient is enabled to separate the 

 gas from an aqueous solution of chlorine, at a given temperature, so 

 cautiously that the drops of the solution may be counted, and the 

 tube through which the chlorine is breathed, shut so as not to lose an 

 atom. A report on this subject by Magendie and Dumeril, was read to 

 the Academy in August last, in which they notice the complete cure 

 of a student of medicine, named Piau, twenty-six years of age. The 

 report commends the apparatus of Dr. Cottereau, but admits that 

 before the efficacy of the new remedy can be considered indubita- 

 ble, many other analogous facts must be produced. — Reports of the 

 Institute for August. 



8. Hydriodic Ether, by M. Sekullas. — Hydriodic ether, for the 

 discovery of which we are indebted to Gay-Lussac, being, like all 

 other combinations of iodine, susceptible of some useful applications 

 in medicine, and perhaps (considering the particular state in which 

 the iodine is found) preferably to any other, I have thought it would 

 not be useless to make known a second modification which I have
