478 BORN (Ig-naz Edler v. [hie Baron Inigo] ) NEW PROCESS of AMALGAMATION of GOLD and 

 SILVER ORES, and other Metallic Mixtures, as introduced in Hungary and Bohemia, trans, by 

 RUDOLF ERIC RASPE, with SUPPLEMENT, or Comparative View of the former Method of Melting 

 and Refining, and Account of its latest Improvements, and of the Quicksilver Trade, with 22 

 copperplates (many folding) of metallurgical plant, 4to. original boards, uncut (RARE), 1. 10s 1791 



The author was the discoverer of a new process of amalgamation first described in tins Avork and of improved 

 methods in several departments of mining. The work is however of still greater interest on account of its translator, a 

 German professor at Casscl, who fled to England to avoid punishment for theft. He was elected a Fellow of the Royal 

 Society, but struck off the rolls on his antecedents becoming known. He was the author of the original ' Baron 

 Munchausen ', and a swindler of a most interesting type. ' In the autumn of 1791 Raspe went on a tour in the extreme 

 North of Scotland, where he professed to discover suns of vast mineral wealth. To sustain his reputation as a mineralogist 

 he brought out, in 1791, a translation of Baron Horn's new process of amalgamation. By plausible manoeuvres he 

 inveigled a local magnate, Sir John Sinclair of Ulbster, into disbursing 1 irge sums for preliminary operations. When the 

 time came for tlie fruition of his schemes, Raspe disappeared. The incident was crystallised in a tradition which Sir 

 Walter Scott utilised in The Antiquary.' D. N. B.
