FUMIGATION WITH PORMALIN.— Formalin is gaining 

 favor as a disinfeetant for elearing rooms elothing etc. from the 

 germs of infectious diseases. For tbis purpose it may be liberated 

 in two forms. The liquid form may be sprinkled about the room 

 or in the receptaele containing the elothing and confined therein 

 for tuelve hours or more. The second form is a powder and is 

 contained in a patent eone. The cone is lighted and by burning 

 or exploding filis the room with the formalin partióles. As with 

 the liquid the room should remain closed for twelve hours or 

 more. 



HOUSEHOLD REMEDIES 



CORROSIVE SUBLÍMATE.— This material is an excellent 

 repellant for the small ants whieh swarm into the houses. It is 

 purchased as a dry powder and is dissolved in either water or 

 alcohol, the latter being preferable. When dissolved in water, 

 the dry powder should be poured into the water a little at a 

 time, until no more will be taken up. If the water is first made 

 briny with salt more of the sublímate will be dissolved. If dis- 

 solved in alcohol 1 oz. of the sublímate should be used to 1 

 qt. of alcohol. 



The prepared solution is painted upon the legs of tables etc. 

 If the wood is unpainted, one application is usually effective 

 for six weeks or two months. 



The material is extremely poisonous and should be care- 

 fully hundled. 



KEROSENE.— Kerosene applied to floors is probably the 

 most effective remedy against fleas. The fleas live during the lar- 

 val stage in the dust of the floors and it is at this time that treat- 

 ment is effective. The keorsene may be applied with an atom- 

 izer, or a bit may be poured on the top of the water in the 

 scrubbing pail, and will thus be distributed when the floors are 

 washed.
