warehouse in which goods are deposited, is a delivery sufficient to transfer 
the property. 1 atk. 171; 5 john. 335; 2 t. r. 462; 7 t. r. 71; 2 campb.

[6] : THE DEVIL'S DICTIONARY ((C)1911 Released April 15 1993)

symbol, n.  something that is supposed to typify or stand for
something else.  many symbols are mere "survivals" -- things which
having no longer any utility continue to exist because we have
inherited the tendency to make them; as funereal urns carved on
memorial monuments.  they were once real urns holding the ashes of the
dead.  we cannot stop making them, but we can give them a name that
conceals our helplessness.
