Charles Clay - Geology, Archaeology, Numismatics

Geology, Archaeology, Numismatics

In spite of the claims of a heavy practice, Clay found time for the pursuit of geology and archaeology. Among the books of which he was the author were a volume of Geological Sketches of Manchester (1839) and a History of the Currency of the Isle of Man (1849), and his collections included over a thousand editions of the Old and New Testaments and a remarkably complete series of the silver and copper coins of the United States.
