00 Lib. 7. D y Pliny, (a) of Pyrrhus King of Epyrus, in which, without 
c 11. much (train of phancy, one might imagine a reprefenta- 
tion of the Nine Mufes, and Apollo, with his Harp, in the 
middle of them. Tis ufed for Sword-Hilts, Knife-Hafts^ 
a m f. B ea ^ s ' C u ps, and the like. There are pieces of it, fometimes 
Septal." ' ® as th^k as a Mans Arm. 
The ONYX. So called, becaufe in colour not unlike the 
Nail of a Mans Finger. Ambrofinus confounds the Agate 
and the Onyx together. But the Onyx differs from the 
Agate, chiefly, in that, inltead of Veins, 'tis generally com-

Balls, one within another : which, when the Stone is po-

An ONYX with a white, and very broad Zone.

An EIGHTH, with an afh-colour'd Pupil, the Iris of a 
pale Amethyftine within, and white without. Thefe with 
more variety of colours, are by fome particularly called 
NICCOLI'j qu. Onyculi. 
A NINTH, which maybe nam'd, The BINOCVLAR 3 
as having the likenefs of two little Eyes. The Table on 
which Nature hath drawn them, is of the colour of yellow 
Amber , and femiperfpicuous. The Eyes are white, with 
their Pupils of the colour of the paleft live Honey, 
A TENTH, diftindly called BELI OCVLVS: the Iris 
whereof is Grey 3 the Pupil, and the reft of the Eye, 
Black.
