BACTERIOLOGY IN A NUTSHELL. 
filtration is in use in some cities. By means of 
the sand the parasitic bacteria are held in abey¬ 
ance until destroyed by the saprophytic. 
Alcohol is used in skin sterilization for the 
purpose of removing oily substances, which pre¬ 
vent the penetration of some other disinfectants. 
Ether is used for the same reason. 
SULPHUR FUMIGATION. 
To Fumigate 
With Sulphur. 
Danger from 
Inhaling. 
To use sulphur for fumigation, take about four 
pounds of rock sulphur (brimstone) for each 
one thousand cubic feet of space. All apertures 
and crevices about transoms, doors or windows, 
etc., must be well packed with damp absorbent 
cotton, or batting, or strips of old muslin, to pre¬ 
vent the escape of the gas. Paste paper over 
openings of grates or registers, key holes and 
speaking tubes. Place an agate-ware, or other 
metal basin or tub, half-filled with water upon a 
firm foundation made of several bricks built near 
the center of the apartment. Have the required 
amount of sulphur on top of some paper in an 
iron kettle sitting in the basin or tub of water. 
Pour over the sulphur a few ounces of alcohol. 
Set fire to the outer edge of the paper and leave 
the room quickly, as the fumes of gas from sul¬ 
phur are dangerous to many people.* Close and 
lock the door, and place a thick rug over any crev¬ 
ice that may be at the bottom. Keep the room 
closed for twenty-four hours, then open up the 
doors and windows and ventilate thoroughly. 
♦The writer remembers an instance in which a nurse 
was almost suffocated by inhaling sulphur gas. She 
thoughtlessly stepped back into the room for a forgotten 
article, and was almost overcome when rescued.
