ABSTRACT
THE extension of bodies in space is in three directions: length: breadth, and depth or height. The path of any real direction, not an imaginary one, is limited; therefore the lines representing these three paths are limited, and their six end-points or limits are the directions. If you imagine an animal in the centre of these lines, i.e. where they cut each other, which turns its face towards one of them, the directions with relation to the animal are before, behind, 1"iyht, left, above, and below.
