by Piiny ^ : The Selenites or Moon-ftone mtift have the precedence, 
which w^ find in great plenty in a bluidi clay that lies above the

4. Where by the way let it be noted, that I intend not by the 
M'oon-flbne^ the grey Tephrites of Pliny ^, that grows like a Crefcent, 
hytht Greeks called Mendl6 \ nor that Other ftrange ftone men- 
tion'd by Tllnymd the Poet Marhodtm corporeally containing 
the Figure of the Mom increafing and decreafing, like that in 
the heavens \ but a ftone fo called, not from its figure, but (as 'tis 
honeftly confeft by Ge/«er " and yl^rico7(7 °) that only reprefents

form of zRhomhoides^ zs'in Tab. 1, Fig. 1. a, and therefore the 
leariied Steno^ (which I think its beft name) not unfitly ftiled it 
Selenites Rhomboides. Befides the two larger Rhomboideal fides, it 
hath eight others of an oblong fquare, in all making up a d^cahe-- 
drum pai allelipipedum ; whereof the fquares of the two ftiorter 
fides of the great Rhomboides^ One is fomtimes a rigbt angled ine- 
quilateral parallelogram^ as in Tab. 2* Fig. i. and the other a 
Rhomboid Ziid fomtimfes again they are both Rhomboids but
