On the Rectification of the Hyperbola by Means of Two Ellipses ; 

 proving that Method to be circuitous, and such as requires much 

 more Calculation than is requisite by an appropriate Theorem : in 

 which Process a new Theorem for the Rectification of that Curve is 

 discovered. To which are added some further Observations on the 

 Rectification of the Hyperbola : among which the great Advantage 

 of descending Series over ascending Series, in many cases, is clearly 

 shown ; and several Methods are given for computing the constant 

 Quantity by which those Series differ from each other. By the
