nut fon which this oil is Pope chiefly by cold-drawing, 
come to their full perfection in the warm climate of the 
fouth of Europe, they will yield, by proper management, 
full half their weight of oil. Recent cold-drawn nut-oil is 
preferred by many to olive-oil, on account of its retaining 
the exquifite flavour of the nut; the hot-drawn has an 
empyreumatic tafte, and is no longer fit for the table: it is, 
however, much value the painter, as being eminently 
drying, much lefs coloured than linfeed oil, and capable of 
bearing the injuries of the weather better cine any other
