1. MEASURE OF LENGTH. 



12 inches = 1 foot

An inch is the smallest lineal measure to which a 

 name is given, but subdivisions are used for many 

 purposes. Among mechanics, the inch is commonly 

 divided into eighths. By the officers of the revenue, 

 and by scientific persons, it is divided into tenths, 

 hundredths, &c. Formerly, it was made to consist 

 of twelve parts, called lines ; but these have pro- 

 perly fallen into disuse.
