The Chalder (of Culross) was 16 Edinburgh bolls.
I need scarcely do more than mention the smaller measures: to the Choppin (Fr. _chopine_), half a wine-pint; to the Mutchkin (Du. _maatje_), its quarter; to the Gill, its eighth, usually.
The measures of Scotland may be thus summarised: They appear to have all come from North Germany, except one from Provence.
The Ell was a length of 3 Rhineland feet, divided into 37 inches, approximately of English standard.
The Acre was a North German acker of 160 rods, each 6 Rhineland feet square.
The Pound was the Amsterdam standard of Troy = 7609 grains, multiplied and divided sexdecimally.
The old wine-boll = 17·8 gallons was the half-Cargo of Marseilles, divided into 16 pints of 41 Scots ounces.
The larger Stirling Jug was a North German ‘kanne’ of 104·2 cubic inches = 55 Scots ounces or 3 Imperial pints. It was the standard of corn-measure; the corn-firlots were multiples of it.
The common corn-firlot was a Rhineland cubic foot = 1000 Troy ounces or 18 Stirling Jugs. It was the North German Himt.
Another firlot was 19 lesser pints = 48-3/4 lb. Scots.
The Edinburgh Firlot of 21-1/4 Stirling Jugs or 2214 cubic inches was the North German Anker, become a corn-measure.
The Firlot of 31 Stirling Jugs was a wheat-firlot enlarged to hold about the same weight of oats.
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.
The general unit is the Cibyn (kibbin) = 4 gallons or 32 lb. of wheat, the English half-bushel or tuffet. It is divided into 4 quarts, and 16 cibyns make a Peg = 8 bushels or 1 quarter.
Measures on the English stone system are also used:
The Ffiol = 1 stone, 14 lb. „ Peck = 3 „ „ Hobbet = 12 „ about 2-1/2 bushels.
There is a Hobbet in England, but this is about a bushel.
