Translation:
The so-called celidonius lapis {"swallow stone"}, which is found in the stomach of swallow chicks - many are sometimes found in just one stomach - some stones are black, some are white and some have some redness in them.
Commentary:
Latin chelidonius is taken from Greek χελιδόνιος /khelidónios/, which means "pertaining to the swallow".
For further information on the beliefs associated with the swallow stone see Lapis chelidoneus.
