Part III. Of Regular Stones. 
A CLUSTERED PISOLYTHOS. It confifteth of Glo- 
bular and bay Stones, united together with an A(h-colour d 
Cement : But this is very hard, and ftirs not with Acids. 
Boetius and others figure a Gutter of thefe, but fo mew hat 
bigger. 
This Stone may feem to belong to the fecond general 
kind above-faid. But is really a heap of diftinct Stones in 
one Bed. Which is alfo to be underftood of others 
alike. 
ANOTHER, compofed of Globular Stones, confifting 
of a whitifh, and foft or friable fubftance5 yet gritty, and 
indiffoluble with Acids. United together with a brown 
Cement. 
A SINGLE one of the fame Figure, but bigger 5 fc. as 
big as a Phyfical Pill. As alfo femipellucid, almoft as the 
bay Amber. Very hard and indiffoluble with Acids. Bejler 
figures fome of thefe, with the Name of Pi fa majora la- 
pidea. 
The SINEPITES, as it may be called. Being a Clufter 
of fmall hard Globules , like Muftard- feeds 5 and united 
together with an obfcure or dull Red Cement. Given by 
Sig r . Boccone. 
The MECONITES. A Clufter of other like Globules 
no bigger than Poppy* feeds. See one of thefe in Boetius 
and Bejler. Thefe two laft, are properly of the Hammites 
kind ; but not the Pifolythos, although accounted fo by 
Boetius. Of thefe Globules, it is obfervable with the help 
of a Glafs, That although they are fo very fmall, yet are 
they ihelFd, 01 compofed of little Balls one within another, 
as the Bezoar-Stone. 
The CLUSTERED STALAGMITES. A Congeries of 
Globular Stones, like fo many petrify'd Drops 3 of the co- 
lour of Oriental Bezgar 5 cemented together with a kind of 
Gypfum. The whole Mafs, which here is polifh'd, is two 
inches and * fquare, and an inch high. This, and the fol- 
lowing Stones of affinity herewith, differ from the five 
former, not fo much in figure, as in fubftance, thefe being 
all inftantly diflbluble with Acids. So that they feem to be 
a kind of Gypfumfitft. diflblved in fome Mineral Menftruum, 
and after fetling in this Figure. 
The CORALLINE STALAGMITES, alfo clufter d. It
