Area, when thus found analytically ; how commodl- 
oufly to fquare the Circle, the Ellipfis, or Hyperbola, 
and how to apply the Quadrature of this laft to the 
computing a Canon of Logarithms; the Construc- 
tion of Tables for the ready finding of Quadratures, 
or the Comparifon of Areas, and how to apply them 
to the folving of other like Problems ; the forming 
of Conftructions, and demonftrating Theorems by 
Fluxions ; the approximating to Areas mechanically, 
and iuch-like. 
From finding of Areas he proceeds to the ReElifi - 
cation of Curves j and firft he Shews how to find as 
many Curves as you pleafe, whofe Curve-lines are 
capable of an exa£t Re&ification. Then he teaches 
us to find as many Curves as we pleafe, whofe Curve- 
lines, tho J not capable of a juft Rectification, yet may 
be compared with the Lengths of any Curve-lines 
aflign'd, or with the Areas of any Curve, when re- 
duced to the Order of Lines. Laftly, He determines 
the Lengths ot any Curve in general, and gives feve- 
ral proper Examples of it. All which elegant Specu- 
lations are managed with admirable Skill, great Sub- 
*tilty, and fine Contrivance.
