1 77, In the Quarry of rubble ftone near Shctover-Ki^X^ I met 
with a Spar-Ilk^ fione^ made I fuppofe of the dropings of petrify- 
ing water, not.unlike to the bags called Manic<£ Hippocrati^^ ufed 
in filtrations by the Chymifts^ three one above another as they 
ufually place them, as in Fig. 10. And in the very fame Quarry 
I found a fmgle Trochites of a cinereous colour, fo called from 
its likenefs to a wheel, having rajs coming forth of its center^ 
like the fpoaks of a Cart-wh el from its (lock, hub, or nave: 
Thefe are faid to have affinity with the Lapis Judaicu/s in their tex- 
ture and with the ^y?m> in the property of moving in Vine- 
gar neither of which I could well try, having but one^ and 
that too fet in a rubble ftone of the Quarry They are found 
plentifully Northward in He/)'- ^7^j?z J, and in the bottom of the 
Chanel of the River Tees ^ at Braughton and Stock in Tork-fiire, 
2Z Beresford'm Staffer d-fiire^^ and are commonly there called 
St. Cuthbert's Beads, whereof 1 intend Cuts^ andlliali treat more 
at large when I come to thofe places. 
178. At the Parifti of Heath I met with a reddifli fort of flone^ 
intheufual form of aWhet-^one, as in Ta6.S. Fig. 11. about 
four inches long, very hard, and for both thofe reafons not fit 
for ufe : it was given me by Mr. Evans ^ Reftor of the place, and 
faid by him to be taken out of a block of ftone dug in the Quar- 
ries thereabout, naturally having grown in that form. And at 
Stonor there was given me a crifp'd white ftone, taken up not 
far thence, xtitmhYingz ^oit of Sweet -meat ^ not like the Co72/em 
de Tivoli^ but rather of Viterho mentioned by Aldrovandm or a 
fort of Sweet-meat we have from Fortugal. 
ij^, Amongft the /]fo;2e^, like things of Art^ I think I muft 
alfo number a fort of globular iron-colour' d balls^ taken up about 
Cornwell ; whereof I have two given me by Sir Thomas Pennyfion ; 
theone//^7i;2 and fmooth, the othti granulated on tht out-iide, 
not unlike to an 6^r^j;7ge, very weighty, and made up within of a 
golden ftriated fubftance from the center to the circumference, 
shewn in the Hemi/phere of one of them. Fig. 1 2. Of thefe there 
arefome fo equally round, as if done by Art; and fo they are
