When I Heard the Learn’d Astronomer!

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.
