I. A letter of Mr. Joseph Williamson Watchmaker, to the Publisher, wherein he asserts his right to the curious and useful invention of making clocks to keep time with the Suns apparent motion

Having been inform'd of a French Book lately published, wherein the Author speaks of making Clocks to agree with the Sun's apparent Motion; and supposeth that it was a thing never thought of by any before himself: I was therefore willing by the advice of some of my Friends, to write this short Account of what I have performed in that matter my self.
