End is not PanBum, but only Signum ( which he does allow non 
ejje nomen §u 0 pi)cxt n this will lerve our turn well enough , Eu- 
clid' % 'Zip* 09, which fome Interpreters render by Signum t others 
have thought he (with Tully) to call PunBum- But if Mr. Hobs 
like not that name, we will not contend about it. Let it b tPuiu 
Bum, brier it be Signum (or, if he p!eafe,he may call it Vexiflum .) 
But then he is to remember , that this is only a Controverfie in 
Grammar, not in M&thematicks : And his Book fhould have been 
intituled Centra Grammaticos,not,Contra Geemctras. Nor is it Eh. 
elide, but Cicero, that is concern'd, inrendring the Greek 
by. the Latine PunBum, not by Mr. Hobs's Signum. The Mathema- 
tician is equally content with either word. 
What he faith here, Ckap. 8 .& 19. (and in his fifth Vial.p. 105. 
gr.)concerning the Angle of ContaB-, amounts but to thus much. 
That, by the Angle of ContaB , he doth not mean either what Eu« 
elide calls an Angle 3 or any thing of that kind^and therefore fays 
nothing to the purpofe of what was in controverfie between 
Clavius and Pels taring, when he fays, that An Angle of ContaB hath 
fome magnitude-!) But, that by the Angle of ContaB, he underftands 
the Crookcdnej f of the Arch j and in faying ,the Angle of ContaB hath 
fome magnitude f\\% meaning is, that the Arch of a Circle hath fome 
crookednef , or, is a crooked line : and that, of equal Arches, That is 
the more crooked, whofe chord is fliorteft : which I think none 
will deny;(Tor who ever doubted.but that a circular Arch is croof. 
<?(5ror,that,of fuch Arches, equal in length fT hat is the more crooked, 
whofe ends by bowing are brought nearejl together > ) Bur, why the 
Croohednefs of anArchfi-\o\H 8 be called an Angle of ContaB -,1 know 
no other reafon, but, becaufe Mr. Hobs loves to call that Chalf, 
which others call Cheefe. Of this fee my Hobbius Heauton-timoru'. 
menus y from pag . 88. to p. lOo. 
What he faitfi here of Rations or Proportions ,and their Calculus 5 
for 8. Chapters together, ( Chap. n.#r,)- is but the fame for 
fubftance, what he had formerly faid in his 4th. Dialogue, and 
eife where. To which you may fee a full Anfwer,in my Hobbius 
Hcauto'.'* tim. from pag 49.10^.88. which I need not here repeat. 
Onely (as a Specimen of Mr* Hobs's Candour , in Falfificati- 
ons) you may by the way obferve,how he deals with a Demon- 
ftration of Mr. Rook's, in confutation of Mr. Hobs’s Duplication 
oftheCubc; Which when he had repeated , pag. 4?. He doth 
then (that it might feem abfiird) change thofe words, (equates
