PINE-OIL AND PINE-DISTILLATE PRODUCT EMULSIONS. Le 
samples examined gave Hygienic Laboratory Soenreles of from 
1.71 to 3.42. 
Emulsions made from the other oils tested gave coefficients under 
1. These preparations failed to emulsify completely in 10 per cent 
concentration. 
Pine-oil emulsions made from various grades of pine oils failed 
to kill W/. aureus and BL. anthracis in any dilution capable of emulsi- 
fication. 
In view of the results obtained these products should not be used 
for general disinfecting purposes. 
When using pine-oil emulsions against 4. typhosus, it is safer, for 
practical purposes, to employ a solution of five times the strength ’ 
capable of killing the organism in five minutes. Thus a product 
showing by the Hygienic Laboratory method a killmg power of 
zt, should be used in a y45, or 1 per cent, dilution. If a product 
will not give a dilution having a concentration five times that of the 
weakest concentration capable of killing B. typhosus in 15 minutes, 
and remain completely emulsified, it should not be used as a disin- 
fectant.
