the Royal Society, and to the Britifh Mufeum. And, 
as this block here defcribed, and the whole contents 
of the pipe, of above forty feet in length, were 
formed in lefs than three years, there is reafon to 
conclude, that the water of this Mine in Somerfet- 
fhire is as capable of being improved to the purpofes 
of a new manufactory, as either that near Bo- 
logna, or thofe of Germany and Bohemia. And it 
is perhaps worth mentioning, that fomething of this 
fort has actually been attempted, with good fuccefs, 
in Peru; for we are told by P. Feuillee {who made 
feveral curious obfervations in South America, both 
phyfiological and agronomical, in 1 709), that he 
law many ftatues and beautiful vafes (or holy water 
pots), in the churches at Lima, which were limply 
call in moulds, by means alone of a petrifying water- 
near Guankabalika, or Guankavelika. And this cir- 
cumltance is alfo mentioned (p. 236.), in a Defcrip- 
tion of Peru, publifhed in 1748, a great part of which 
is taken from Feuillee’s account. 
6thly, This block of marble takes a very fine 
polifh, as appears by the fpecimen, the feCtions of 
which are polffhed ; and if calls of medals, or other 
things, were taken in fmooth moulds, well formed, 
their furfaces would, therefore, probably appear well 
polifhed, as thofe of the medals did, which came- 
from Bologna.
