5. The third Pent agon on sVld^it is not near fo broad, as either 
of the former ^yet one I fouad amongft a 100 of this fortjthat 
u full as large as any of the above- defcribcdv Thefe are all 
convex on the one fide and fomewhat hollow on the other 5 
thick edged 5 one of the s fides only is indented j the inden- 
ted fide is ever the rhinneft, and the ftone is moft floped to- 
wards that fide* that there are many amongft thefe laft 
iodented forts of plates^whicharechanoelled on the concave 
fide and otherwife notched. 
4. All ihtitFentagonous plates are to be found plentiful- 
ly at Braugkton or Stocl{. But I fiiall not omit in this place the 
isientiooing of one^I by chance efpicd amongft certain figu- 
red SrooH^which I had out oftheQaarrie near Wansford-bxiAg 
in Northamptonfhire^ and it probably belongs to thefe kind of 
plates I am now in hand with Jt has one of the five fides thick 
indeored ; the convex part has in the middle a raifcd Vmboj 
like fome antient fhields^ and round about the fides a lift ©f 
finaller Studds. We have fioce had fome plates muck like this 
from Bugthorp under the Woolds in Torl^JhirB. We proceed to 
remaike fome differences in the fex-anguUr plates* 
5. All thefe ftones are but fmalljfavehcre and there one: 
The firft of them is but little hollow on the one fide,and con- 
vex on the other 5 having the convcx-fide moft elegantly 
wrought with railed or cmbofled work^ that is^ with an equi- 
lateral triangle beftridingcach Coroerjand afingle right line 
in the midft 5 or^ if you will, two Triangles one within ano- 
iher^ Thefe we found at Branghton-fear only. 
6. That Plate-ftone . which is moft common in thefe Rocks, 
there teiog a looc of thefe to be found for one of the other, 
h fexangular^z little hollow on the one fide and convex on 
the other : They are for the moft part foiooth on the convex 
fide or fcabrous osjly^fome are much thicker than othcrs^fome 
being as thick as broad, but moft are Plate-like h the fides are 
very unequalj as in Gryftals^ foractimes five broader fides and 
one very fmall 5 again two fides broad and four much nar- 
rower^ and infinite other differences as to the inequality of 
fides.
