(cended in double branches and points^ which near the rim were 
included in oval Annulets ; the double and -protuberant points 
of thefe , about mid-way to the rim are turned into fingle , 
though much larger ones, as inTab. 3. Fig. i. which now de- 
fcend'ing in fingle and meeting \mnVmbiHcu6 not in the 
middle of the bafis^ but fo much to one fide, that the branches 
upon this account being fome longer fome (liorter, and croffing 
the bafis in a much different manner, make a figure fomwhat re- 
femblinga F lower- Je-lis^zs in Tab. 3. Fig, 2. which had been all 
I (liould have faid concerning thefe BrontidC^ but that perhaps it 
may not be unworthy our notice. 
1. That the protuberancies of this lafi: /lone are all hol- 
low, which when broken, look juft like the hollow 
points of the former ; which has given me fome 
ground to fufpeft, that the deep points of that may 
have formerly been eminencies like the m^ed points of 
this, and are only broken down by the injuries of 
time. 
2. That none of thefe Brontide have been defcribed be- 
fore, but the 12 and 13 pf Tab, 2. which indeed are 
fomwhat like the 8 and i o of Aldrovandu^ ^ : and 
3. That though fome Authors have thought them the 
petrified ftiells of the Echinm Spatagm^ or Briffu6 of 
u^ri^fotle, I have reafon to think (as ftrall appear in a 
fitter place) that they will prove nothing lefs. 
38. BcMc the Brontice o{ the Foneign Naturalifls^ we have 
others, which herein England we call likewife Thunder-bolts^ in 
the form of arrows heads^ and thought by the vulgar to be indeed 
the darts of Heaven : which only in conformity to my own Coun- 
try (though for as much reafon as the foregoing Brontide) I have 
placed amongft the /o/^ei related to the Heavens. ■ 
39. From their form., by all Naturalifts they are called Bele- 
mnites, from the Greek word BiM^m telum^ which indeed there 
are fome of them reprefent pretty well. We have of- them in 
Oxford-fiire of divers forts, yet all of them I find agreeing in 
this , that their texture is of fmall ftride^ or threds radiating 
from the center^ or rather axi'^ of the Stone, to the outermoft 
fuperficies and that burn'd, or rub'd againft one another, or
