Astronomy expalined upon Sir Isaac Newton's Principles, and made easy to those who have not studied Mathematics...

"Fifth edition, corrected"; the first edition appeared in 1756 and went through at least thirteen editons. It was also translated into Swedish and German. This is one of the earliest and clearest explanations of Newtonian theories. Ferguson (1710-76), a skilled designer of clocks and planispheres, was an accomplished public lecturer and the unofficial "popularizer in residence" to the court of George III. The frontispiece depicts his famous orrery. " His models of the planetary system were classics of engineering design whose accuracy far surpassed anything previously available."
