25 6 Of Animal Bodies petrify d. Part HI. 
Beafts and Men, in Flints. Sept alius hath a Head in Mar- 
W°f Gems n e- And Mr. Boyle (a) a Pebble with a Serpent (all but 
the Head ) per tartly ihap’d, and coy I’d up in it. All tliefe 
(except perhaps the laft ) are either femblances on a Plain, 
or at lead in folid Stones. But this here is hollow, and 
was fo found in the JJland-Sea. About five inches long 5 
now fplit into two halfs, like thofe of a carting Mould. 
On the infides of which, are fairly imprefs’d the form of 
the Spine , with the Ribs, Fins, and Tail, of a Filh. With¬ 
out, a long Plate of the fime fubftance, grows to each 
fide 5 and others crofs to thefe: as if to the Mould of the 
Filh, were alfo added that of its Funeral Cloaths. 
This Stone, for confidence, is like that called Saxum 
Limofum, foft, inequal, and unpolifhable. Of a blewifh 
hue, like that of Tobacco-Pipe Cby, with fome very frnall 
glofly Grains intermixed. Not only Spirit of Nitre, but 
Oil of Vitriol droped upon it, diflolves it, and is excited 
into a violent Eftervefcence. But the Saxum Limofum dirs 
not with any Acid. So that it is to be rank’d amongd the 
Gypfo-limofa , or Calcilimofa. 
A petrify’d BONE,taken out of a Gravel-pit in St. James 
Fields , above eight yards deep.

Philip Skippon. It may be called SPONDYLITES. 
Part of the SPINE of another Fifh, confiding of feve- 
ral Vertebrae. ’Tis hard and ponderous ; yet diflbluble 
with Acids. It breaks flaky, as the Lapis Judaicius, and 
many others, or with plain and glofly hides. 
The TOOTH of a TIGER,growingtoakind of Lime- 
ftone. ’Tis about as big as that defenbed in the Firfl Part, 
and of the fame fbape and colour. 
A fquare crooked TOOTH, not much unlike that of 
a Bevir. 
A very great DOUBLE TOOTH or GRINDER. ’Tis 
about five inches long, and two broad; twice as big as a 
Sea-Horfe s. The flumps feern to have been fiw’d off. The 
top divided into feveral Points and Ridges, as other double 
Teeth. Of agreyiih colour and glofly; ponderous, and 
hard as a Flint or the hardefl Pebble. 
ANOTHER of the fame lhape, but not an inch long. 
Befler hath one like this, under the Name of Pfeudocorona 
Anguina. The
