Mesozoic. Some species of the Coal-measures reach into the "Rotlilie- 

 gende," as for instance Cyatheites arborescens, Walchia piniformis and 

 some JVixr/fferratkife ; while other leading plants of the Rotliliegende, 

 as Annularia carinafa, Calamites infractus and others have their nearest 

 relations in the Carboniferous Annularia longifolia, Calamites approxi- 

 malus, etc. The Flora of the Rothliegende "very closely approaches 

 that of the Coal-measures, although along with the characteristic Palso- 

 zoic genera, there are some others that have their largest expansion in 

 the Mesozoic. The Dyas or Permian is hence pronounced to be P;i!«.> 

 zoic as well on the ground of its organic remains as its stratigraphical 

 relations.

4. Dana's Geology. — This long expected volume will appear in a fe« 

 T^'eeks. It will be published by Theo. Bliss & Co., Philadelphia, m JJ 

 8vo volume of about TSO pages, beautifully illustrated by about 100" 

 wood cuts, drawn chiefly from American examples or the authors own 

 experience. It will be looked for we know with pleasure, not more ro 

 its own sake, than as an evidence of the returning health of its autftor.
