The beautiful comet of 1811 became the object of that celebrated astronomer's conscientious labour.

On top of the meteor shower, a bright and beautiful comet was also visible from the sky.

It was, perhaps, both as seen by the naked eye and with the telescope, the most beautiful comet of which we have any record.

Herschel thought, as I have already said, that the beautiful comet of 1811, and that of 1807, were self-luminous.
