Open an oyster, retain the liquor in the lower or deep shell, and if
viewed through a microscope, it will be found to contain multitudes
of small oysters, covered with shells, and swimming nimbly about; one
hundred and twenty of which in a row would extend but one inch. Besides
these young oysters, the liquor contains a variety of animalculæ, and
myriads of three distinct species of worms, which shine in the dark
like glow-worms. Sometimes their light resembles a bluish star about
the centre of the shell, which will be beautifully luminous in a dark
room.
