Mystery Hunt Mystery Hunt
Here we go round the Mystery Hunt
At five o'clock in the morning.

Between the Infinite 
And the River
Between the Three
And the Four
Lie the clues
   For thine is the Answer

Between the physicist
And the chemist
Between the geometer
And the astronomer
Lie the Initials
   Hunt is very long

Between HENRY and MORSE
Between EVCLID and HIPPARCHVS
Between PASCAL and DAVY
