and boiled it in water J till it had altogether put off its falin 
tafte, and that then he would have found, it would not have 
imbibed fait anew , any more than any other body calcin'd. 
Tis true, faith tic, feeing the Air is full of falin fteames , it 
cannot be otherwife , but that that cadaver of fait, having 
admitted the impreffion of the corpufcles flying in the Air , 
will tafte faltlfh upon the Tongue, as all other bodies ; that have 
paft the fire, will do the like. 
He relateth further, that two yeares agoe, when he was at 
MoMe^mClivo Scattriy there was digg'd out a whole houfe, 
which for above 10 Ages had been buried , from under the 
roots of herbes in a Garden of a Cittizen, a Houfe of a very 
handfome flru&ure., of Corinthian-work % and that there he met 
himfelf, among the ruder a, very many vafa lacrymalia of Glafs-, 
which by length of time were become laminated into divers 
leaves, beautifyed with pavonaceous colous : the places like 
to Muscovji-Glafs, fiffil into leaves. 
He maketh alfo mention of a vegetable feed , very com- 
mon in the Fields of Denmark, which having been once 
heated red-hot, and then taken out and pot in a cool place , 
would remaine hot and burning for fifty Houres toge- 
ther. 
He defcribes alfo the method, which a certain Abbot, call'd 
BoneaudiuS) ufed to obtain a perpetual Heat 5 which was, that 
he thruft into the Earth a Pike of about 20 foot long, and ha- 
ving thereby made a deep hole, ( which was to be fecured 
from the falling in of other matter) he poured into it tgfl 
pounds of Mercury, which by its ponderofity and the yielding 
of the fubjacent foft Earth ( for if that were hard and fto- 
ny, or had fprings of water, the efFe£t was not like to follow) 
would continually fink lower and lower, and in fome Moneths 
time infinuate it felf into the lowermoft parts of the Earth , 
and there meet with the Chambers of the fubterraneous Heat 5 
which iffuing forth through that hole uneeffantly, would mo- 
derately warm and cherifh whatever fliould be placed over it 5 
and fo furnifli us with a perpetual fpring of warmth. Which 
device feems to our Author to be countenanced by what Aco- 
fia relateth////?. IndJ.^. viz. That in Gmncavdica in
