190 Method of preventing Worms 
Put a quantity of the best olive oil into a phial with two 
or three times as much water, so that the phial may he 
about half full. Shake the phial briskly for a little time, 
turn the cork downwards, and let most part of the water 
fiow r out between the side of the cork and the neck of the 
phial. Thus the oil must be washed five or six times. — 
After the last quantity of water has been drawn off, what 
remains is a mixture of water, oil, and mucilage. To 
separate these from eaeh other, put the phial into hot 
water for three or four minutes, and most part of the wa- 
ter will fall to the bottom, which must be drawn off as be- 
fore. 
The oil must then be poured into a smaller phial, 
which, being nearly full, must be well corked, set in a 
cool place, and suffered to stand undisturbed for three or 
four months, or until all the water shall have subsided, 
with the mucilage on the top of it, and the oil, perfectly 
transparent, swimming upon the top of the mucilage. 
When time has thus completed the operation, the 
pure oil must be poured off into very small phials, and 
kept in a cool place, well corked, to preserve it from the 
air.
