Prefaces and Introductions are commonly esteemed the last words of the Author, put in the first place, as his right rather than the reader’s privilege, to vex and impede the inclination to get at the main design; and for this reason are very often passed over. But the Author begs leave to say—that in this instance, the Introduction is the Key.

It will be found, that the minor part of the Title indicates the major of the subject in respect to importance, though not perhaps in matter for amusement.
