2. Ireland
There are in Ireland many primitive Celtic measures worthy of study, if merely as showing the ways of thought of the people; but apart from these, the system of weights and measures, established for many centuries, has been the English system introduced in early Plantagenet times.
Some of these measures, relics of that time, long overlaid in England, are of interest; for instance, the gallon of 217 c.i. is one-eighth of the early wine-bushel = 1 cubic foot.
The Irish road and field measures, multiples of the seven-yard rod, have been noticed.
