When I heard the learn’d astronomer, 
When the proofs, the figures, were ranged in columns before me, 
When I was shown the charts and diagrams, to add, divide, 
   and measure them,
When I sitting heard the astronomer where he lectured with
   much applause in the lecture-room,
How soon unaccountable I became tired and sick,
Till rising and gliding out I wander’d off by myself,
In the mystical moist night-air, and from time to time, 
Look’d up in perfect silence at the stars.

And finally.....

Let's Dance!
