      waste products from the animal body; a urinary gland.
      [1913 Webster]

   Note: In man and in other mammals there are two kidneys, one
         on each side of vertebral column in the back part of
         the abdomen, each kidney being connected with the
         bladder by a long tube, the ureter, through which the
         urine is constantly excreted into the bladder to be
         periodically discharged.
         [1913 Webster]

   2. Habit; disposition; sort; kind; as, a man of a different
      kidney. --Shak.
      [1913 Webster +PJC]

            There are in later times other decrees, made by
            popes of another kidney.              --Barrow.
      [1913 Webster]

            Millions in the world of this man's kidney.
                                                  --L'Estrange.
      [1913 Webster]

            Your poets, spendthrifts, and other fools of that
            kidney, pretend, forsooth, to crack their jokes on
            prudence.                             --Burns.
      [1913 Webster]

   Note: This use of the word perhaps arose from the fact that
         the kidneys and the fat about them are an easy test of
         the condition of an animal as to fatness. "Think of
         that, -- a man of my kidney; -- . . . as subject to
         heat as butter." --Shak.
