(1725? – 1790)
Pryce had an interest in the Pednandrea mine for ten years. During that time, he made a detailed examination of Cornish mining. He was fascinated by the Newcomen engine and had a chance to study it firsthand because there were more than 70 of those marvelous engines working in Cornwall. (For a discussion of the steam pumps and the engines used in the tin mines of Cornwall, see: Fleming and Brocklehurst, A History of Engineering, pp. 114-8.) He had a tremendous interest in ancient Cornwall and formed a renowned collection of antiquities of the region. His Archæologia Cornu-Britannica (London, 1790) contains Pryce's observations including a valuable vocabulary and grammar of the Cornish language.

Very scarce. Mineralogia Cornubiensis is the first great classic devoted to mining in Cornwall and it was considered the standard for its time. It as been called the Cornish "De Re Metallica," with some justification, since it is a comprehensive digest of mining practices in the region. In it are described the mineral structure of the Cornish metal mining areas and the relationships between the various kinds of ore-bearing lodes. This encyclopedic work is embellished with diagrams, glossaries of technical terms and fine engraved plates. A large plan and map of North Downs Mine, a depiction of a section of Bullen Garden Mine, and a detailed engraving of a "Steam Fire Engine" (the Newcomen engine) with a table caluculating its power to draw water are included. Pryce also discusses at length the "rag and chain pump" which was still used by manual labor to dewater mines, although the method had fallen into disfavor during it the early 1770s. The author also describes the mineralized zones of Cornwall and their relationships with each other, finally tabulating the knowledge in diagrams and glossaries.
