The translation of the fon^oing work, with an appendix not contalneil in the original. It Is of special Interest on 

 account of its translator, a German professor at Caasel, who fled to Englan<l to avoid punishment for theft. He was elected 

 a Fellow of the Royal Society, but stnick off the rolls on his antecedents becoming known. He was the author of the 

 original ' Baron Munchausen ', and a swindler of a most intorestlng type. ' In the autumn of 1791 Raspe went on a tour In 

 the extreme North of Scotland, where he profe.ssc<l to discover signs of vast mineral wealth. To sustain his reputation as 

 a mineralogist he brought out, in 17JU, a translation of Baron Bom's new process of amalgamation. By pUiusible 

 mano'uvres he inveigle*! a local magnate.Sir John Sinclair o| Ulbster,lntodisbursmg large sums for preliminary operations.
