 Saturn (lead), Mars (iron), Mercury (mercury or quicksilver), 

 Venus (copper). The tortoise above and the fish below belong

PREFACE TO THE SECOND EDITION 



THE few printer's errors discovered in the first edition have been 

 corrected, but no substantial change has been found necessary 

 in any part of the book. From the favourable reception it has 

 met with it is gratifying to the author and to the publishers to 

 infer that the information contained in it has been acceptable to 

 many of the public in the United Kingdom and the Colonies as 

 well as in the United States of America.
