PREFACE.

Priestley, a Black, or a Davy, to direct your efforts. If you cannot procure an orrery, intend" ed to illustrate at one view the numerous and complicated motions of all the bodies in the solar system, but fitted to confuse and bewilder the mind, take an orange or an apple and show simply and clearly the shape, surface, and motions of the earth.

"If you have not a complete set of mechanical powers neatly constructed, and finely polished by the hand of a physical instrument-maker, use a cane to show the principles of the lever, and the first circular pulley within reach to prove that the lever, the pully, and the wheel-axle, are but varieties of the same thing. If you cannot give lectures with logical arrangement, rhetorical figures, and rounded sentences, congratulate yourselves that ideas are better than sounds, and facts than flourishes. If you cannot learn in detail all the minutia in a complete system of science, prove by some simple experiment a single practical principle, which you can constantly witness in the motion of limbs, in a wheel, a ́plough, or an edged tool. If every person cannot be a profound or a critical scholar, he may be an enlightened, respectable, and useful citizen."

To our patrons we would say, that the future numbers shall in no way be inferior to those of the present volume; indeed, every effort shall be made to render them more worthy their notice. May we solicit their recommendation? They can, with confidence, say, that in it will be found much instruction and amusement, and not one line that can offend the eye of the most strictly moral and religious man; indeed, where an opportunity has occurred to revert to the sublime truths of Christianity, and to the all-wise Creator of the Universe, it has been embraced-for

The introduction of new inventions seemeth to be the very chief of all human actions. The benefits of new inventions may extend to all mankind universally, but the good of political achievements can respect but some particular cantons of men. These latter do not endure above a few ages-the former, forever. Inventions may make all men happy without either injury or damage to any one single person. Furthermore new inventions are, as it were, new erections and imitations of God's own works.
