tracted or shortened and enlarged on the other. The fossil plants 

 - lit exactly the same appearance, the dimor- 

 phism of the ferns being there still far nion dNiiu \\\ marked 

 than in the species figured by Heer, and the nervation rendered 

 quite as obscure by the superposition of the coating of hard coaly 

 matter, a, don of the epidermis by heat. I 



haw tried to explain the deformation of the ferns, as a result of a 

 slow movement of upheaval in successive undulations oi the strata 

 as it is remarked along the beach of Newport; a movement 

 winch. wld in a soft state, caused an exten- 



sion or traction to one side, and therefore this peculiar deforma- 

 tion of the leaflets when placed on one side of the line of the force 

 of upheaval. Another r markable coincidence is, that Xevropte-

Professor Heer has, it seems, opportunity to study plants of 

 most of the geological formations of Europe, and indeed his pro- 

 found knowledge of fossil l.otanv seems to render every work 

 related to this science an easy task for him. lie has aKo recently

 The work exposed in this short review, and which scarcely repre-

 make an honorable record for a whole scientific life.
