FIRST EDITION, published after the appearance of Halley\'s comet in December of 1758. Winthrop endeavors to calm the fears of people by explaining the science behind the comet\'s appearance, just as Halley had predicted it. Winthrop was the great-grandson of his namesake, who founded the Massachusetts Bay Colony. He taught mathematics and natural philosophy at Harvard College, and wrote a number of other tracts on natural phenomena (such as the Lisbon earthquake of 1755), explaining the science behind their occurrence.
