An act of this date established that a penny (money) should weigh the same as 32 grains of wheat, twenty pennies to make one ounce, and twelve ounces to the pound. Eight pounds was to be the weight of a gallon of wine. You will notice the link between money and weight, and that 240 pennies equals one pound.

1707 - reign of Queen Anne
The wine gallon, which was fixed at 231 cubic inches. This is the basis of the liquid measures still in use in the US of A. It must be said that this gallon is actually of Edward the first's time, the 1707 act really only clarifying its size.

The 'L.s.d.' system of money was replaced with the 'decimal' system.
