Good. FIRST EDITION OF THIS GEOLOGICAL STUDY OF ST. MICHAEL; WRITTEN BY A HARVARD PROFESSOR WHO LATER MURDERED A FELLOW PROFESSOR OVER A LOAN DISPUTE. In 1847, Webster borrowed $400 from George Parkman, securing the loan with a cabinet of minerals. When Webster gave these minerals to another party to secure a second loan, Parkman (understandably) became incensed. He confronted Webster, they argued, and Parkman disappeared. Parkman?s remains were discovered in Webster?s laboratory; after a sensational trial, Webster was convicted and later hanged. Measurements: 9 x 6 x 1?.
