THE

PREFACE.

HE Perfons for whofe Sake and Ufe the following Treatife was at first drawn up, (or rather I should fay, as to the greater Part

of it, this Collection made out of many other and larger Books) are chiefly fuch, who, though they have not the Opportunity of attending to the more abftruse Parts of Mathematic Science, are defirous at least, of fome general Knowledge in these Matters; fuch who, though Providence has marked out their Tract of Life amidst Scenes of worldly Business, yet have Souls large enough to extend themselves, now and then, beyond this little Planet, and take a distant View of more remote Worlds; in the Contemplation of which, both the philofophic and pious Mind may find Entertainment and Profit. The Works of the Lord are great,
