brass-work, pianos, telephones, instruments, etc., are 

 present. 



SulpJmr.—-2 lb. to 1,000 cubic ft. The pots 

 containing the sulphur are to be placed in pans con- 

 taining 1 in. of water. The sulphur is to be started 

 by alcohol, and care must be taken to see that it is 

 well aliglit. Duration, three hours. Brass-work and

 A room has a refreshing smell after its use. 



Four ounces are vaporised per 1,000 cubic ft. for 

 two hours ; the material is placed in an open pan 

 placed over a spirit or petroleum lamp, white vapour 

 is given off. 



To test the efficiency of the fumigation, it is very 

 useful to enclose some twenty or more mosquitos in

 mosquitos should be dead at the end of the fumigation. 

 They should be kept, however, to see if they revive. 



Avoid risk of setting fire to the premises by using 

 care and foresight.
