 the Baltic. Twenty small lakes, forming narrow groups to 

 the south and west of Lake Istaca, have received from M. 

 Nicollet the names of distinguished European astronomers, 

 adversaries as well as friends. The map thus becomes a

 names of new genera of plants were adapted to the Court 

 Calendar, and to the various changes taking place in the 

 Oficiales de la Secretaria. 



To the east of the Mississipi dense forests still partially
