132 Uses of Chlorides and Chlorine. 



It has happened that in our two manufactories of porcelain 

 ware, the white enamel of the vessels, by being incidentally exposed 

 to a rupture of foul emanations of this nature before it was perfectly 

 dry, has become vjery much discolored. A remedy has been found 

 in opposing solutions of chlorine to the current of sulphuretted hy- 

 drogen, although the emanations have continued for weeks together. 



7. In destroying emanations that may occasion a plague. 



M. Felix D'Arcet, a member of the committee sent to Egypt in 

 order to make experiments relative to the plague, furnished M. de 

 Lasteyrie with the following details extracted from a letter from 

 Tripoli of June 14, 1829. 



"The most important point to be determined was whether the 

 pestilential virus could resist the action of the chlorides. 



" The Vice Consul of France obtained for us six garments of per- 

 sons who had died of the plague, all within the last two days. These 

 garments were soiled with blood, sanies, and sweat. After the Con- 

 sul had taken an account of their condition, I immersed them during 

 sixteen hours, in a solution of chloride of sodium, and after drying 

 them, each of us put on a shirt next to our skin, and then the re- 

 mains of the dress. The spots still existed on them but much faded. 

 We slept in these garments, and after wearing them eighteen hours, 

 replaced them. It is a week since the experiment, and neither of 

 us have experienced the least change. Our natural constitutions are 

 also, it may be remarked, very different." 



It was proposed by M. Pariset that the effect of chlorine should 

 be tried on other contagious diseases, and accordingly three exper- 

 iments were made with it, in relation to the measles. The chamber 

 of a child, exposed to the measles, was disinfected, and his shirt was 

 dipped in a solution of one ounce of liquid and concentrated chlo- 

 ride of hme, and three gallons of water. When dried it exhaled, 

 very slightly, the odor of chlorine. — He escaped the infection. 



8. In the cure of epidemic diseases among dumb creatures. 



In 1829 an epidemic malady broke out among fowls in the vicinity 

 of Paris. The disease spread rapidly, manifesting itself by an in- 

 flammation of the head, tears in the eyes, blueness of the skin, and 

 the issue of blood from the beak. The animals soon sunk under it. 

 Bleeding and other means of restoration were employed without ef- 

 fect. The author being consulted, directed the chickens which were 

 still unaffected-, to be placed in an enclosure by themselves, and those 

 on which the disease had made some progress, in another enclosure.
