Neither hide nor hair

Usually in the form of ‘I have seen neither hide nor hair of that person for some time now’ which means there has not been the faintest trace of such person, literally, not a piece of skin (hide) nor a follicle of hair. The expression in this sense seems to be of American origin from the mid-19th century, and supposedly derives from hunting speech. A much earlier and now largely defunct expression, ‘hide and hair’, meaning wholly or entirely, is much older and is first recorded from at least the 1400s.
