STANDARD RBCEIPTS. 463 



COPPERAS (Sulphate of Iron), one and one half pounds to a gallon 

 of water is used in cesspools and sewers. 



COMMON SAIvT AND SULPHATE OF ZINC (White Vitriol), 

 four ounces of each to a gallon of water to disinfect clothing and bed 

 linen. 



CORROSIVE SUBLIMATE. (Bichloride of Mercury), sixteen 

 grains to a quart of water, is used to receive discharges from the body, 

 when the patient has cholera, tj^phoid fever, etc. The quantity used 

 should equal the amount of discharge. This is very poisonous, and 

 must be used with greatest caution. 



CHLORIDE OF LIME. This is a very valuable disinfectant, but it 

 will discolor clothing that has coloring matter in them that will be at- 

 tacked by the free chlorine given out from the compound. Clothing is 

 best disinfected by common salt and sulphate of zinc. Use chloride of 

 lime, one pound to three gallons of water, to sprinkle on floors and 

 wash out sinks that are offensive. Dry chloride placed in rat-holes from 

 which come offensive odors, will soon purify the atmosphere. It should 

 be used in urinals, night commodes, water-closets, privy-vaults, butcher 

 stalls, slaughter-houses, fish-markets, pig-pens, and stables, especially 

 if the latter are near the house. Use it freely whenever a contagious 

 disease or an epidemic of any nature is in the neighborhood. 



How to Use Disinfectants. All clothing, towels, and bed-linen 

 before removing from the room, should be placed in a tub of boiling salt 

 and zinc solution. All discharges should be received in vessels which 

 contain either the corrosive-sublimate or the copperas solution. 



Prevention of Diphtheria. " Every person in contact with a per^ 

 son afflicted with diphtheria should use disinfectant gargles as a prevent- 

 ive. A physician should prepare the gargle and give directions for its 

 use. 



Prevention of Typhoid Fever. This disease is largely trans- 

 mitted through the passages from the bowels. Some one of the disin- 

 fectants should be used in the commode, allowing the stule to pass di- 

 rectly into the liquid prepared as suggested. Corrosive-sublimate, (bi- 

 chloride of mercury ), is the most efficient. Sulphate of zinc, (white 

 vitriol), is also very valuable. If proper care be taken in this regard 

 there is very little danger of typhoid fever being transmitted to another 

 person. 



Scarlet Fever and Measles. These diseases, while disinfection 

 does not prevent their being contagious, seem to be modified by the
