3.1 then aflumed 
three Poles C, D and 
S, and fuppofed one 
of the Angles SNL, 
to have its angular 
Point N carried over 
the Curve A N, while 
the Leg N pafTes 
always through S, as 
in the Defcription in the Treadle of the General 
Defcription of Curve Lines, while the Angles QJD R> 
RCP, revolve about the Poles D and C : I fuppofe 
alfo the Interfedions Qjind Rto be carried over the 
Curve Lines B Q, G R, and that the Dimenfions of 
the curve Lines AN, B Q, GR, are /;/, r, re- 
Ipedively ; and find that the Locus of P may be of 
3 mnr Dimenfions; but that the Point C is fuch, 
that the Curve pafles through it as often as there 
are Units in inmr. 
4, If any number of Poles are aflumed, fo as to have 
Angles revolving about them, as about C and D in 
the laft Article, and the Interfedions are carried 
over other Curves, the Dimenfions of the Locus of 
P will be equal to the triple Produd of the Number 
of Dimenfions of all the Curves employed in the 
Defcription.

ble Angles P N R, A

while the Sides P N
