The last-mentioned goods may be sold either by the heaped measure or by the standard weight (see the article Weight); but for all other kind of goods not usually sold by heaped measure, which may be sold or agreed for by measure, the same standard measure shall be used, but it shall not be heaped, but stricken with a round stick or roller, straight, and of the same diameter from end to end.

The following tables, which are in accordance with the new standard, it will be proper to insert in this place: -

An inch is the smallest lineal measure to which a name is given, but mechanics subdivide it generally into eighths and sixteenths; measures or "rules " are however constructed by the rule-makers with every possible variety of subdivisions or scales of the parts of an inch that can be required by artificers, engi neers, and scientific persons.

The following particular measures of length are in general use:-
