H E Book confifls of three Parts. In the firfl. 
called Logometria, the Author’s chief Defign is 
to lliew how that fort of Problems, which are ufually 
reduced to the Quadrature of the Hyperbola and El- 
lip fat may be reduced to the the Meafiires of Ratio’s 
and Angles ; and afterwards be folved more readily 
by the Canons of Logarithms and Sines and Tangents. 
He defines the Mealures of Ratio’s to be quantities of 
any kind, whofe Magnitudes are analogous to the 
Magnitudes of the Ratio’s to be meafured. In this 
Senfe any Canon of Logarithms is a Syftem of nume- 
ral Meafiires of the Ratio’s of the ablblute Numbers to 
an Unit : The Parts of the Afymptote of the Logifiic 
Line, intercepted between its Ordinates, are a Syftem 
of Linear Meafiires of the Ratio’s of thole Ordinates : 
The Areas of an Hyperbolut intercepted between its 
Ordinates to the Afymptote, are a Syftem of Plane 
Meafiires of the Ratio’s of thofe Ordinates : And fince 
there may be infinite Syftems of Meafiires according
