P a r t* HI. Of Regular Stones, 501 
being given and repeated for above five days together. 
See one or two very remarquable Hiftories hereof in Boe- 
tim. (a) (a) De Lap. 
The Larger Hollow STALACTITES, or WATER- & Gem - Lib - 
PIPE. The Greek. Name fuppofeth it to grow fomewhat 
after the manner of Icicles, from LapidiftckzWaters. Yet 
how it (hould grow hollow, as this, is fomewhat hard to 
conceive. For hereby, it feems rather to grow or fprout 
upward , as the Stelecbites. Only with this difference, 
That as that grows from an open Bed : this probably, from 
one under Water. Whence I take leave for the Englifb 
Name. Tis three inches long, in thicknefs equal to the 
little Finger. Of a Cylindricf^ Figure, faving that at both 
ends 'tis a little more {lender 5 whether naturally, appears 
not. Compofed of feveral alh-colourd and blackifh 
Crufts , exceeding thin crifpe and brittle , not ill re- 
fembling a rouled Wafer. The Bore is lined throqgh with 
a fmall granulated Candy. 'Tis inftantly diffolved with 
Spirit of Nitre. 
ANOTHER, confirming wholly of white Crufts or Wafers 
one within another. 
The SMALL WATER-PIPE, lis a Clufter of very 
fmall Tubes, with the Bore fo fmall, asfcarcely to be feen 
without a Glafs. Rough all over with a tuberous Cruft. 
They are found in Germany, Moravia, and other Parts. 
One Drachm hereof in Powder , is a potent Sudor i- 
A Stone like a Pebble with fmall TUBULAR KNOBS Lap * & °' 
upon it, like the Primordia of a Water-Pipe . They are 
fo fmall, that their hollows cannot be obferv d without a 
Glafs. The Stone on which they grow, though very hard, 
yet makes a ftrong Efervefcence with Spirit of Nitre. Thus 
far of Cylindrick^ Stones. 
The CONICK STALACTITES, folid. Tis about three 
inches long 5 the top fharp, the middle * an inch over $ * 
the bafe, an inch, with four or five excentrick Crufts. The 
whole compofed of feveral Crufts, one within another, as 
the Water-Pipe. Yet not hollow, as that, or rather not 
empty, but filled with a Red ftony fubftance. Being 
kroken, it (nines like the Lapvsjudavcm. Without, fmooth* 
of an Alh-colour, with fome little caft of red. Inftantly 
diffolved
