312 Of Regular Stones. Part IIL 
of a dirty afh-colour : in fubftance, not unlike the Lime- 
ftone. The other, fomewhat harder $ runs through it in 
feveral Veins, or rather P latest being ufually plain, as thick 
as the back of a {lender Knife, and exactly of the colour of 
yellow Wax 5 for which caufelhave plac'd it amongft the 
Plated Stones, and taken leave for the Englifh Name. Both 
of thefe two Bodies make an Effervefcence with Spirit of 
Nitre, but the afh-colour d, the greater. 
The PIPED WAXEN-VEIN. So I call it, for that the 
greater afh- colour 'd Body inclofed within the yellow Plates, 
is fluffed top full of fmall Cylinders and Tubes irregularly 
placed : moft of which feem to be of the fame yellowilh 
fubftance, as the Plates. This Species hath fome affinity with 
the piped Ofteocolla above defcrib'd. 
The STARRED WAXEN-VEIN. Given by Sir Rob. 
Moray. Found in the Ifle of Sheapy. On one part of the 
Stone grows a fair Star, with many Rays, about an inch 
long, white and glofty : from whence I name it. This 
Star is of a quite different nature from the Stone on which 
it grows, as making no Effervefcence with Acids, and in 
figure agreeing rather with the Pyrites. 
A Piece of WAXEN VEIN, with doubled Plates] in 
fome places, as it were efflorefcent with feveral little pro- 
tuberances confubftantial. 
From the Defcription of this Stone above given, it ap- 
pears, that Wormius was miftaken, in reckoning it amongft 
Flints. This is that, which Paracelfus fo much extols for 
a Lithojitriptick. And thus far I believe, that 'tis a very 
good Viureticki and may therefore fometimes be very 
well ufed for the carrying off of Gravel. But let all that 
have any Stone too big to be voided, take heed of fuch 
Medicines. 
PLATED MARBLE. It feems to have been originally a 
ftriatedBole. Now a Stone ^^rd^Marble^compofed 
of Portions, of an inch thick,^a^^^^^^^Scolour I, 
growing parallel, or as it were ftratumfuper ftratum 5 from 
whence I have nam'd, and here placd it. 
Several foft PLATED STONES, found in the fame 
place, and of the fame colour and fubftance, with the Fijh- 
Mould formerly defcrib'd. One of them, Globular a
