The instrument serves a dual purpose, assisting in the solution of problems of the calculus of classes (into which propositions of Aristotelian logic may first be cast), and of a crude but early logic of probability. There are two slides, the 'gray' and the 'red'. The gray slide is placed in a slot at the left, except when used for probabilities, when it is placed in a slot at the top.

Stanhope printed on his own press several chapters of an unfinished work entitled 'The Science of Reasoning Clearly Explained upon New Principles', which circulated among only a few acquaintances. He occupied himself with the study of logic for about thirty years, from 1787 to his death in 1816. Reference: Robert Harley, Mind, vol. 4 (April, 1879).
