 with sealed notes added to them, having on the outside the 

 same motto, and the author's name, quality, and place of 

 residence within. The note of the piece lo which the prize 

 is adjudged shall be opened, and the rest shall be burnt un- 

 opened. 



The tracts, legibly written, maybe either in Russian, French, 

 English, German, or Latin, and must be addressed to the 

 permanent secretary of the academy, who shall deliver to 

 any person, the author may appoint, a receipt, marked with, 

 the same number and motto marked on the piece. 



The successful memoir is to be the property of the acade- 

 my, and without whose formal permission the author shall 

 not print it: the rest of the tracts may be received back from 

 the secretary, who will deliver them at St, Petersburgh to 

 any person commissioned by the author to apply for them.
