130 §—S—«SUU ses of Chlorides and Chlorine. 
newly painted, and carefully closed. ‘The chlorine emanating from 
the chloride from the decomposing action of the carbonic acid ‘of 
the atmosphere will spread through the apartments and neutralize the 
odor of the paint. 
- If it be desirable also to remove the dampness of the apartment, @ 
few pieces of chloride of calcium, (or muriate of lime, ) pest in 
earthen dishes in the room, will answer the purpose. 
It is wrong; in such a case, to use fresh lime, along with the chlo- 
ride, because the latter is effectual only in proportion as the chlorine 
is disengaged by the action of the carbonic acid and moisture of the 
air, and the presence of quick lime only serves to attract the same 
things, and therefore to retard the decomposition of the chloride. 
The same purpose, as it regards odor, may be effected by the 
separation of chlorine gas, by placing an earthen cup, contaiming aa — 
of oxide of manganese and three ounces of hydrochloric 
(muriatic) acid, on a hot brick, or over a furnace with a few live 
or in a vessel of hot water, stirring the materials, and — 
the apartment for twenty four hours. 
By heating in the same manner chloride of lime, dissolved in or 
mixed with water sharpened with sulphuric acid, the same purpose 
is effected. 
2. The use of chloride in correcting the unhealthiness of manufac- 
tories of cat-gut, or other fabrics from animal materials. 
Manufactories of this nature are apt to emit a highly disagreeable 
odor. The free use of chlorine, liberated in the way aboye indica 
ted, will effectually correct the unhealthy emanations. 
3. In disinfecting the mud and filth of sewers. 
_Agreeably to the experimental investigations of a committee cho- 
sen by the police, it appears that it would require 576 grammes of 
dry chloride of lime to disinfect one cubic foot of semi-fluid muds 
weighing 10 kilogrammes, or 620 grammes of chloride, one foot 
more solid filth weighing 10 kilogrammes 50 dec 
The expense, therefore, deduced from these dais. of disinfecting 
sewers which have become very foul, is considered to be too great, 
even at the reduced price of chloride of lime, and they therefore 
prefer the purification by ventilation through the agency of fire. 
4. In disinfecting the air of rooms in which silk worms are kept. 
The experiments of M. Bonafous, very carefully conducted, have 
proved that silk worms, exposed to the putrid exhalations of their 
litter and excrements, to the odor of dead worms, &c. will-te injure
