Physicotheology First Edition 1720 William Derham by William Derham instant download after payment.

In 1696, he published his Artificial Clockmaker, which went through several editions. The best known of his subsequent works are Physico-Theology, published in 1713; Astro-Theology, 1714; and Christo-Theology, 1730. All three of these books are teleological arguments for the being and attributes of God, and were used by William Paley nearly a century later.[3] However, these books also include quantities of original scientific observations. For example, Physico-Theology contains his recognition of  natural variation within species and that he knew that Didelphis virginialis (the Virginia opossum) was the only marsupial in North America. It also includes one of the earliest theoretical descriptions of a marine chronometer, accompanied by a discussion of the use of vacuum seals to reduce inaccuracies in the operation of timepieces. He is the first person known to have used the word chronometer.[4]
