Original covers lost, now bound in paper, probably later in the 18th century. First page bears the stamp of University Library, Cambridge.
A pamphlet published no doubt to be presented to the Board of Longitude in an attempt to win the £20,000 prize.
The first part of the pamphlet concerns a type of quadrant invented by Rowe.
The second part, pp. 13-47 is an "Essay on the Discovery of the Longitude, By a New Invention of an Everlasting Horometer: Founded on the most Unerring Principles of Nature."
An introduction gives reasons why clock and watchwork will not be able to determine longitude.
The Horometer is described and illustrated and consists of tubes and chambers of bizarre shapes containg large quantities of mercury.
