Yet, this is not always the case and there are familiar objects that violate this mass / weight proportionality.

The add-on code is often one of the following: the last four digits of the box number (e.g. PO Box 107050, Albany, NY 12201-7050), zero plus the last three digits of the box number (e.g., PO Box 17727, Eagle River, AK 99577-0727), or, if the box number consists of fewer than four digits, enough zeros are attached to the front of the box number to produce a four-digit number (e.g., PO Box 77, Juneau, AK 99750-0077). However, there is no uniform rule, so the ZIP+4 Code must be looked up individually for each box.

Written in 1611 or 1612 for his wife Anne before he left on a trip to Continental Europe, ``A Valediction'' is a 36-line love poem that was first published in the 1633 collection Songs and Sonnets, two years after Donne's death. Based on the theme of two lovers about to part for an extended time, the poem is notable for its use of conceits and ingenious analogies to describe the couple's relationship; critics have thematically linked it to several of his other works, including ``A Valediction: of my Name, in the Window'', Meditation III from the Holy Sonnets and ``A Valediction: of Weeping''.
