The O^aturdl Hijlory 
fcraped with a knife, they yield an odour like rafped Horn. 
40. In magnitude and colour they differ much, the biggefl: I 
have met with yet, being that expreft in Tab. 3. Fig. 3. in length 
fom what above four inches, and mthicknefs mach about an iwc/^ 
and^. This was found in the Quarries in the Paridi of Hedding- 
ton^ hollow at the top about an inch deep, and filled with a kind 
of gravelly earth ; and has the r'ma or chink.^ which Aldrovan^ 
dm and Boetiws fay all of them have ; but I find itotherwife, as 
ftiall be (liewn anon. Of colour it is cinereous^ inclining to je//orr, 
and if vehemently rubb'd, is the only one amongft all that I have, 
that like Amber takes up ftraws^ and fome other light bodies. 
41. There are of them alfo of z bluifi colour^ found at Gre^/ 
Rolwright in 2 bluij/j chy, of about a fingers length, hollow at 
the top, and have fome of them., inftead of one, three clefts or 
r/W, but neither fo plain or long as the former, they afcending 
from the cufpi^ fcarce half up the ftone : two whereof are fliewn 
Fig, 4. and the third hidden behind the Sculpture ; which may 
make fome amends for that of Fig. 5 . which is of colour cine^ 
reou6 and hollow at the top, but has no chink at all ; whereof 
there was a bed found in dicing the Sulphur Well at Mr. Lanes 
of Veddington^ as was mentioned before in the Chapter of Wa- 
ters, 
42. To which add ?. fourth fort, found in great plenty in the 
Gravel-pits without St. Clements^ in the fuburhs of Oxford^ very 
few of them hollow at the top like the former, but radiated like 
a Har^iom a clofer center^ as in Fig. 6^. which made Gefner"^ 
think it to he: the jjlrapias of Pliny ^ though exprefly he fays, 'tis 
of a vphite or azure ^, whereas this is always of an amber colour : 
yet draws not draws, is fomwhat tranfparent, and may therefore 
pafs for a fort of Lapis Ly neurit ; not that it has original from 
the urine of that Bea/l^ for we have plenty of the ftones here and 
none of t\\t animals^ but from the unpleafant fmell it has when 
burn'd or brayed ; like the urine of Cats^ or fuch like ramifh 
creatures, whereof the Lynx perhaps may be one. Thefe, mod 
of them, are made tapering to a point like the former ; yet fom- 
times having a blunter ending, and the chink on both fides, I 
thought fit rather to fliew it in that form than the other, as in 
* Thefe not being hollow at the top, nor containing any other ftone, gravel, or earth, fome call the 
male Be/ewzw/Vfj-! the three former being of the female kind. " De Figuris La^idum, cap. w Naf,
