Gallon

[L. Fr. galon; L. Lat. galo, qq. v.] A measure of capacity, adopted in New-York as the unit or standard from which all other measures of capacity are to be derived and ascertained.

1 Rev. St. [608,] 617, § 11.

The gallon for liquids is declared to be a vessel of such capacity as to contain, at the mean pressure of the atmosphere at the level of the sea, eight pounds of distilled water, at its maximum density.

Id. ibid. § 13.

This is the same as the old English gallon. See Galo. The gallon for dry measure is declared to be a vessel of such capacity as to contain, at the mean pressure of the atmosphere at the level of the sea, ten pounds of distilled water at its maximum density.

Id. ibid. § 14.
