 the price of each Part from One Guinea and a half (as announced in the original 

 prospectus) to One Guinea ; but the Edition will b i strictly limited to 1000 

 copies, of which only about 2o0 will be available for Europe and America. 



The work will be issued in Thirteen Parts (to Subscribers only) at the price 

 of One Gui7iea each, or Tioelve Guineas for the whole if paid in advance.
