The JASPACHATES. Tis polifh'dTand fo figu^dTas 
to look like one half of a Pear, with the Stalk, Coar, and 
dead Flower cut out. Curioufly beautify 'd with Yellow, 
Purple, and Blood-red Spots, immerfed in the Horny and 
Semiperfpicuous colour of the Agate 3 with which alfo 'tis 
equally hard. This alfo is a kind of BLOODSTONE: as 
all other Jafpers with red Spots. 
The JASPONYX. Tis polifti d with an Oval Figure. 
Com poled of white Zones, befprinkled with White^Brown, 
and Red Spots. 
. Another of a courfer kind, composed of Green and Afh- 
colourd Plates. Like that Marble defcnbed by bnperatus 
with parallel black Lines. 
The JASPAMMITES. So I call it 3 Having the Figure 
of the Ammites , with the Colour and Hardnefs of the 
faffk. For 'tis compofed of little orbicular Stones, fome- 
what bigger than a Pepper-Corn 3 all green without, and 
of a dark Purple in the centre. So as they feem alfo to 
have been once little crufted or ftielPd Balls, as thofe of the 
Ammites, hereafter defcnb'd. 
The Jafpis grows in India, PhrygiaJThracia, and Bohemia. 
Next in hardnefs to the Agate. Sometimes fo big, as to 
be ufed for Statues. Of great efteem, as an Amulet, for 
the ftainching of all Hemorrhages. Of its .Effedt herein,

The NEPHR1TICK-STONE. Of affinity with the 
Jafpis, and rather harder. Of feveral colours 5 but no 
one of two, nor any Red : for the mod part of a pale 
Green. It hath fome fofter parts intermixed, which make 
it look fometimes as if it were a little oily 3 and for which
