explanation of the paper marked "2." Unmeaning
To systematize a plan for my work I arranged the papers in the order of their length, and numbered them, designing to commence with the first.
Length may be distinguished from height, which is vertical extent, and width or breadth, which are the distance from side to side, measuring across the object at right angles to the length. Length is a measure of one dimension, whereas area is a measure of two dimensions (length squared) and volume is a measure of three dimensions (length cubed). In most systems of measurement, the unit of length is a base unit, from which other units are defined.
