The {oft OVAL HELMET STONE. Given by Sig c . 
Boccone. So I name it from its limilitude to the fhell of the 
Echinus Sgatagus , (a) which the Englijh call Helmet-Fijh. [if 
Oval, to diftinguifh it from the Conick, Soft, as being very 
brittle, and eafily diifoluble with Adds. Several of thele 
Stones are figur’d by AUtovandus , ( b) with the Name of fi) Mufeum 
Scologendrites. And fome leaves after, divers others not Metallio 
much unlike, with that of PentaghyHites from its liknefs in 
fome part alfo to the Cinquefoyle.

rows, compofed of fine fhort Rays, and meeting in the 
form of a Crofs 5 to which a fifth is added, more broad. 
Tis fomewhat hard, yet diifoluble with Spirit of 
Nitre.
