4. " Notice of the Number of known Fossil Plants at different 

 Epochs, and of the Natural Orders to which they are referred," by 

 Prof. Balfour. After alluding to the division of the Fossil Epochs 

 as given by Brongniart, viz. into the Reigns of Acrogens, of Gym- 

 nosperms, and of Augiosperms, Dr. Balfour proceeded to give an 

 analysis of the orders of Fossil Plants as given by Unger. The fol- 

 lowing general tabular view was compiled from Unger' s work : —

These plants are arranged in different strata as follows : —

After alluding to Sir Charles LyelPs observations on the Flora of 

 the Carboniferous Epoch, as given in his late introductory discourse 

 to the Geological Society, Dr. Balfour referred to Raulin's account
