SUPERFICIAL MEASURE,' 
May be estimated either duodecimally, or vvhere 
the sides are measured in feet and parts of a foot, 
decimally ; if in the latter, the area will be expressed 
in feet and decimal parts of a foot, instead of being 
expressed in feet, inches, primes and seconds Scci 
and when requisite the decimal parts of the footj 
may be converted into duodecimals by constantly 
multiplying such decimal parts by 12, and the re^. 
suit will be old inches, primes, 
There will be no alteration in land measure^ 
which may either be decimally expressed, in square 
chains and decimal parts of a chain, or reduced as 
now usual, to acres, roods, perches, and parts of a 
perch; for the chain will still continue to be sixty- 
six feet in length, divided into 100 links, of the 
same length as the present link ; for 6 new inches 
and T^ths are precisely equal to 7 old inches and 
Tw of an inch. 
CUBIC measure, or measures of capacity. 
Let the unit of measures of capacity be the pre¬ 
sent Winchester bushel of 2150.4 cubic English 
inches, equal to 1244new or standard inches, 
and let the least measure be a metre, or cube of one 
new inch, and let the series be as in the following
