exactly perpendicular to the Horizon ; but in every 
indifferent Direction they pointed forth very plenti- 
fully of feveral Sizes; fometimes in Groupes and 
Cluders, fometimes fingle, now eroding each other, 
and now (landing by each other with parallel Sides : 
Some were fmooth, fhining, and clear, others rough 
and opaque; fome vcin’d with red, like Porphyry; 
others fpcckled thick with the fmalleft Spots of deep 
Purple, and a bluifh Cad : But the fined of all jwere 
thofe which had innumerable little Diamonds or 
Sparks (of the cleared Water) duck upon their Sides, 
and, by means of the Candle, had a Ludre not to be 
conceived. We gazed here in this incommodious, 
but beautiful little Cave, till we could no longer 
hold up our Heads ; and then crept out as we came 
in, upon our Knees. 
Now, among the great Numbers of fparry Pro- 
ductions which 1 faw in this Mine, I could not ob- 
ferve, but that they pointed indifferently in all man- 
ner of Directions ; which 1 fuppofe owing to the 
great Unevennefs of the Surface on which the Bafes 
of thefe little Columns were fix’d ; and for the fame 
Reafon I doubt not, but in all concave Beds the Points 
converge, as in all convex they turn the contrary 
Way, and diverge, as from a Center : So that the 
natural Caufe of thefe different Directions is pro- 
bably no other than the accidental Form of that ge- 
neral Mafs from whence thefe Shoots proceed. I 
would fay, that as the Figure and Regularity of the 
lapidific impregnated Matter happens to be when 
drained of all fuperfluous Moidure, and by the Cold, 
Heat, or Dryth, difpofed to (hoot, fo will the Ten- 
dency of the Shoots, both Column and Point, be. If
