The last three fac-similes were obtained by Dr. Bolton in 

 person, through the courtesy of the Director of the Royal 

 Cabinet of Coins, Vienna, and prepared through the courtesy 

 of the Keeper of Coins, British Museum. 



In describing the foregoing medals and coins of hermetic as- 

 sociation, Dr. Bolton narrated the circumstances connected with 

 the alleged transmutations which they commemorated, giving 

 anecdotes of the credulity of the royal or ducal patrons of the 

 knavish alchemists who preyed upon them. He referred, in 

 closing, to some modern treatises on alchemy, notably that of 

 Cambriel (Paris, 1843) and that of Tiliereau (second edition,. 

 May, 1889), in which the authors, undaunted by the exposures 

 of modern science, boldly offer to teach the transmutation of 

 metals — for a consideration.
