the countries of the Continent ; and is found, in great 
abundance, in Siberia. 
97. RED JASPER is an opaque red stone ivhich is found 
embedded in red day-ironstone in Baden ; and is cut and 
polished for various ornamental purposes. There are 
extant many fine antique engravings on red jasper. 
98. EGYPTIAN PEBBLE is a kind of jasper, that is 
found in globular or rounded pieces, and is distinguish- 
able when cut or broken, by its numerous colours, arranged 
in concentric stripes or layers. It is chiefly brought 
from Egypt ; and, as it is capable of receiving a fine 
polish, and when polished is very beautiful, it is manu- 
factured into several kinds of ornamental articles. 
From the great abundance in which it is supplied, it is, 
however, much less valuable than carnelian (93). The 
colours of the Egyptian pebble frequently assume very 
singular forms. There was one in the Leverian Museum 
which exhibited, in. the centre, the resemblance of a 
pantaloon, or a man wearing a fool's cap. 
99. STRIPED, or RIBBON JASPER, is marked 'with al- 
ternate stripes of different colours ; and is found in 
Siberia, Saxony, and even in the Pentland hills, near 
Edinburgh. It receives an excellent polish, and is fre- 
quently cut into the tops and bottoms of snuff-boxes. 
The red and green layers of jasper, being well defined 
and regular, this kind is used for several purposes of 
ornament, particularly for cameos. 
100. AGATE, or AGATE JASPER, as some mineralogists 
denominate it, is a semi-transparent stone of' the quartz family, 
which is capable of receiving a high and very beautiful polish. 
These stones are always found in a shapeless or massive 
form, and nearly of all colours, except bright red and green. 
The name of agate is derived from the river Achates, 
in Sicily, in the vicinity of which these stones were 
obtained by the ancients in great abundance. They are 
now found in several parts of Scotland ; in Iceland, 
Saxony, and Hungary; and they are occasionally 
brought into Europe from China and the East Indies.
