and hardnef^i much like a Pebble^ and of colour ydlowiftj\ divi- 
ded firft by five pretty ftraight lims^ adorned on each fide with 
double fets of points^ afcending from a frotuberant itmhilicu6 in 
the ^bafis of the fiom^ to another of like form at the top, but fo- 
liated round in manner of a : And after again fubdivided by 
five other indented lines^ terminated before they reach the umbi- 
lici ; by which means the fpaces between thefe lines are all penta- 
gons^ like the outer fcales of lome fort of 7or/c//e. Much fuch 
anothery?o«e asthis I find m Aldrovandu^^ in his Book VeTefta- 
ceis'', which becaufe he thought refembled the feaVrchin depri- 
ved of its outward prickly coat, he calls Echinws lapi6 fl^oliatma 
fui^ ]fini6 : But it feeming to mc to be much more like the Eftrice 
marino ^ fi ritrava ncUi mari profondi ^ of Ferrante Imperato^^ I 
chufe rather to call it Hiftricites^ or Forcupine-fiojie without bri- 
ftles. This was found in the Chiltern Country, near Stonor- 
houfe ^ and fent me by the Worshipful Tbo, Stonor Efq; the 
Proprietor of the place, and one of the Noblefi Encouragers of 
this Defign. 
§2. And fo was the following curioufly embroider'd /lone, 
Fig.^. much refembling the petrified Riccio marino^ or fea Urchin 
of Imperatm % found in the fame place alfo without/^ricWe^, but 
much differing from the former in colour and fubftance, as alfo 
from the flone of that Learned Author : For whereas he confeffes 
that was but of the confiftence of the Lime-fione ; ours, though 
without of a whitijb cinereous colour, within is a hard black, flinty 
covered over with thin glittering plates , fet edg-ways to the 
ball of the flint, out of which thofe uniform eminencies diwd. de- 
prejfures^ tho^e vraved and tranfverfe lineationszre all framed.

by the Country men there, fays the Ingenious Boccone^ , called 
Mamelles de Saint Paul^ becaufe of the lenticular eminencies and 
fmall roundures^ that fill the whole furface of the ftone ; or rather 
becaufe they are fomtimes found coupled two and two, as may 
be feen in the /cw//>///re^ of the fame Author. By Boetins and 
Gefner, and all the old Authors^ they are called Ova anguinay 
Serpents eggs ; perchance becaufe from the Z'^yJ^ there iiTue as it
