The doctrine of ultimators. Containing a new acquisition to mathematical literature, naturally resulting from the consideration of an equation, as reducible from its variable to its ultimate state: Or, a Discovery Of the true and genuine Foundation of what has hitherto mistakenly prevailed under the improper Names of Fluxions and the Differential Calculus. By Means of which We now have that Apex of all Mathematical Science entirely rescued from the blind and ungeometrical Method of Deduction, which it has hitherto laboured under; and made to depend upon Principles as strictly demonstrable, as the most self-evident Proposition in the first Elements of Geometry. By the Reverend Mr. John Kirkby, Vicar of Waldershare in Kent.
