bright yebow. It is ufed by the inhabitants as a 
gentle coirolive for eating off proud deffi. There is 
another of a darkei colour, and a much harder nature, 
which is found at the very mouth of the fpring, where 
it burfts out of the rock. There are other forts taken 
out of the fubterraneous cavities of the fpring at the 
time it was cleaned. In what manner they are formed, 
is not fo eafy to determine ; unlefs there were, an op-

Brudel fpring. They found there the fame kind of

fort of pifolithi, molt of them in a globular, but 
fome in an oval form, from the fmalleft fize to the 
bignefs of a nutmeg ; the former fort lying in maffes, 
the latter generally ffngle and detached : they are
