' Introducing the true method of flvxions, most of the books that have hitherto appeared on that subject having in 



them little more than the name, the principles on which they have proceeded being the same with the differential 



calculus ; so that by calling a differential a fluxion, and a second differential a second fluxion, etc., they liave so confusedly 



jumbled the methods together, that people who have not been thoroughly acquainted with them, have been led into many 



mistakes.'— Jntro.
