Mz. WarzuRTON was so good as to bring me a specimen 
of this curious flint coralloid found at the bottom of the 
chalk-cliff on the eastern side, at Rottingdean in Sussex, 
where it is said to be very abundant. It is almost always 
the nature of flint to be formed into some shape expressive 
of its having been in a state of solution. This is every 
where evinced by the various substances it has taken pos-~ 
session of, but the distance of time since this happened 
cannot be positively ascertained ; for although it is in a 
sort of stalactitic form, running like a gelatinous substance, 
yet it is always in a hard state, and looks as if it were 
almost recent, although it may have been for many ages in 
the same state. I have a piece of Coral from the neigh- 
bourhood of Bristol, by favour of Thomas Meade, Esq., 
which has Flint and some Calcedony passing into its in- 
terstices.
