CHAP. 35.—TWENTY-FIVE REMEDIES DERIVED FROM BUTTER.
From milk, too, butter is produced; held as the most delicate food among barbarous[2265] nations, and one which distinguishes[2266] the wealthy from the multitude at large. It is mostly made from cows’ milk, and hence its name;[2267] but the richest butter is that made from ewes’ milk. There is a butter made also from goats’ milk; but previously to making it, the milk should first be warmed, in winter. In summer it is extracted from the milk by merely shaking it to and fro in a tall vessel, with a small orifice at the mouth to admit the air, but otherwise closely stopped, a little water[2268] being added to make it curdle the sooner. The milk that curdles the most, floats upon the surface; this they remove, and, adding salt to it, give it the name of “oxygala.”[2269] They then take the remaining part and boil it down in pots, and that portion of it which floats on the surface is butter, a substance of an oily nature. The more[2270] rank it is in smell, the more highly it is esteemed. When old, it forms an ingredient in numerous compositions. It is of an astringent, emollient, repletive, and purgative nature.
