Wc have faid , that gtocrally the outmoft Circle of eacli 
joy at is flat aod fmobihsyet are there many pthejr differences 
to be cored as to that Part ; Very probably becaufc they are 
Parts or Pieces of different Species of rockc^lants. 
I • That the fmooth-joynted (to fay no more of them here) 
are of different thickntfles as to the joynts. 
2. Gn fome Entmhi htimxt Suture and Suturein the mid-* 
die of each joync, are ccrtaio Knots in a Circle 5 the joynts 
thus diftioguiflbed are very deep and large, and are very fre- 
quent a C4yi^(?(?4 
3. There arc likewife of thefe with a circle of knots, which 
have many knots bcfides upon each joynt and look rugged* 
4> Some with much thinner joynts^which yet have a Cir- 
cle of knots in the middle of each joynt 5 and this alfo looks 
as though it was all over knotted , aod thefe are found at 
onlyj as far as 1 know. 
5, As fome have bm oneGircle of knots,othcrf are knotted 
all over the joynt and rough ^ fo are there (ome others,which 
have a Circle of larger knots ia the middle of each joynt,and 
a circle of kffcr on each fide clofe adjoyning to the border 
or verge of the Suture^Tbis ishuge pr€tty,and they are found 
.at Stock: 
64 Others betwixt Suture and Suturein the middle of each 
joynt rife with a circular edge^ 
7* A frooothliis^lmA^/witha large or much rifeo edgon 
the middle of one of the joynts^ and a much ftnaller on the 
middle of in other joynt aod that alternatively. 
8. The fame alternate difference , the joynts only much 
rounder and blunr^ and here the joynts are vifibly one thic- 
ker than the other* 
9. The fame with alternate edges kpotted* 
10* A double edgin the middle of every jaynt 5 this makes 
the joynts look as though they were exceeding thin and nu- 
coerous^ but indeed they are not fo. 
If. A double edgin the middle of every /oynt knotted 
by iotervalsjor as it were ferrate edges. 
Andthefe are fome of the differences, that I have at pre- 
fent been able to make dut. Some of the Pieces of mdft, if 
not all, of the differences of ihefe Entrocki zv^ ramous , ha-
