	ELL. A measure of length. In old English the word signifies arm, which sense 
it still retains in the word elbow. Nature has no standard of measure. The 
cubit, the ell, the span, palm, hand, finger, (being taken from the 
individual who uses them) varies. So of the foot, pace, mile, or mille 
passuum. See Report on Weights and Measures, by the Secretary of State of 
the United. States, Feb. 22, 1821; Fathom.
