Ay, in the catalogue ye go for men; As hounds, and greyhounds, mongrels, spaniels, curs, Shoughs, water-rugs, and demi-wolves, are 'clept All by the name of dogs: the valued file Distinguishes the swift, the slow, the subtle, The housekeeper, the hunter, every one According to the gift which bounteous nature Hath in him closed.
William Shakespeare, A. R. Braunmuller (1997). “Macbeth”, p.166, Cambridge University Press
