Lord Macaulay’s

Cut off my head, and singular I am;

Cut off my tail, and plural I appear;

Cut off my head and tail, and, wondrous feat!

Although my middle’s left, there’s nothing there.

What is my head, cut off?—a sounding sea;

What is my tail, cut off?—a rushing river;

And in their mighty depths I fearless play,

Parent of sweetest sounds, yet mute forever.

Dr. S. Weir Mitchell’s
