capillary glass tube by placing one end in the drop of 
blood and lowering the other end enough to allow the 
blood to flow in easily, until the tube is one-half full. 
If a capillary tube is not at hand, the blood may be 
collected on a glass slide or on glazed paper, like a 
calling card. The blood drops should not be smeared 
out but allowed to dry as drops. 
Throat Cultures. 
Outfits for making throat cultures are supplied 
by the Bureau of Health in most cities, and consist of 
a sterile swab in a test-tube and a tube of culture 
medium. The patient is placed in a good light, the 
tongue held down by a tongue-depressor or spoon- 
handle, and the swab rubbed over the inflamed part 
of the throat. The material on the swab is then 
rubbed directly over the surface of the culture medium. 
After use the swab may be burned or replaced in the 
tube and sent with the culture. 
Pus. 
When the amount of the pus is sufficient, it may 
be collected directly into a sterile test-tube. If cultures 
are made, the swab and culture tube of a throat-cul¬ 
ture outfit may be used. The pus is collected on the 
swab and then rubbed over the culture medium, just 
as in making a throat culture.
