a measure of capacity both for dry and liquid things, containing four quarts; but these quarts, and consequently the gallon itself, are different, according to the quality of the thing measured: for instance, the wine gallon contains 231 cubic inches, and holds eight pounds avoirdupois, of pure water; the beer and ale gallon contains 282 solid inches, and holds ten pounds three ounces and a quarter avoirdupois, of water: and the gallon for corn, meal, &c. 272 cubic inches, and holds nine pounds thirteen ounces of pure water.
