UPPER CHALK. 
mediately behind the village ; it formerly produced 
numerous remains of fishes, palates, teeth, &c., but 
is now seldom worked. It is, however, deserving of 
attention, on account of several thin veins of pure 
dint that fill up vertical fissures in the chalk, and 
which, to use the language of Sir H. Englefield, 
“ appear exactly as if the flint, not being quite 
hard when the fissures took place, had been 
squeezed out of the beds, and had run into the 
fissures as soft pitch would do : I do not mean that 
this was the case, but merely to describe the ap- 
pearance.” * 
Steyning chalk-pits. These produce belemnites, 
plagiostoma, dianchorm, teeth, palates, &c. The 
sulphuret of iron found in these quarries is of a 
very singular form, being cylindrical, with a small 
projection at both extremities. Chalk-pits near 
Arundel abound in fishes, palates, teeth, marsu- 
pites, and others of the most interesting organic 
remains. 
MINERALS. 
In the iqiper chalk the minerals are but few in 
number, and, like the lower chalk, it contains but 
one metalliferous ore. 
1. Crystallised quartz : this is of frequent occur- 
ence in the cavities of siliceous nodules, shells, &c. 
The form of the crystals is that of a six-sided 
pyramid, their colours varying from a reddish 
brown to a light blue, amber, grey, and white.
