trude themfelves into the Shape they feem inclinable 
unto ; fo they lie blended, and their Lineaments 
fcarccly to be diftinguiftfd from the general Mafs. 
Some Spars rife out of the general Surface, into 
large orbicular Bliftcrs, thick fet with hexagonal 
Points diverging, as Rays from a Center. Fig. 9.

Thefe Blifters or Protuberances are in other Spars 
lubdividcd into Numbers of other fmall, orbicular 
Excrefccncies, and the Cnfpides very fmall, but, like 
the pointed Shoots of moll Cornifb Spars, hexagonal.

At the Root, or where they join to the Rock, 
thefe globular Malles fhew in what Direction the 
Juice exerted itfelf, fpringing commonly, as from 
one general Center, and extending itfelf equably on 
every Side. When the Juice is ftmple, and of one 
Sort only, the Rays are continued from the Center 
to the Extremities } as Fig. 11. Tab. IV. But when 
the Juice is of two or more different Mixtures 
and Impregnations ( which will generally appear 
from the different Colours and Degrees of Tranfpa- 
rency),then theEffort is various and fucceflive,protrud-

Activity of the Stamina , of which itconfifts; and in 
both thefe Cafes I find the coarfeft and moft terrene 
Part of the fparry Lump next the Center, and the 
moft tranfparent and pureft fhot forth, to form the 
pyramidal Cufptdes of the Circumference. Though 
the Effort is various and multiple, the fcvcral Juices 
preferve a Parallelifm to each other, and to the Ex- 
tremity, each juice proceeding no farther than its 
own
