Mr. William Phillips on the 
with the stratum for a short distance, projecting beyond the face 
of the cliff from a few inches to two or three feet. A fan-shaped 
projection of this kind overhangs a copious stream of pure water 
issuing from the grey chalk, termed Lidden spout, protruding be- 
yond the surface of the cliff, not less than five feet. 
Not a flint is visible in this bed : its organic appearances are 
numerous, but do not differ considerably from those of the superior 
strata. Along the crevices running parallel with the stratification, 
the chalk is commonly of a deeper grey than the bed in general,, 
and incloses some still darker appearances of ramification, resem- 
bling in their general form some varieties of broad-leaved fuci, 
which are somewhat softer than the chalk in which they are 
imbedded. The reverse of this is occasionally observable in the 
more solid parts of this chalk, and where its colour is of a lighter 
grey ; for there it is sometimes traversed in every direction by very 
numerous and small ramifications of a colour still lighter. The 
remains of the echinus are numerous, and their shells are replaced 
by carbonate of lime of a grey colour : every one I saw had not 
only suffered depression, but the shell was also in every instance 
broken ; a circumstance which is the more remarkable, as it is rarely 
discoverable in any of the superior strata;. 
Small masses of pyrites are very common, and there are some of 
singular forms. Thin strings of it, sometimes ramified, the branches 
terminating in a point, are very numerous ; but sometimes on the 
contrary they are terminated by a spherical bulb, or by one that is 
elongated and resembling the head of the alcyonium, but very small ; 
these are generally hollow. A remarkable crystallization of pyrites 
is also very common. A string of octohedrons piled with con- 
siderable regularity on each other, and above am inch in length, is 
crossed by another similar to it, — the termination of each being the.
