moist atmospliere (not at all likely to have been charged with more 

 carbonic acid gas than that of our own day) would encourage the 

 growth of cellular parasites and epiphytes, &c., probably repre- 

 senting races much higher in organization than the cryptogamic 

 trees on which they flourished. The examination of the Flora 

 of the Coal Period reveals to us an assemblage of plants agreeing 

 in all essentials with some of the humble members of our present 

 Flora, but attaining at so early a period in the history of the 

 world, a development, not only in size, but in organization, greatly 

 in advance of their modern allies.

 Geology and Palaeontology, including a Sketch of the Geology of 

 Nice."

 measures," by Mr. T. P. Barkas. 



4. "On the Genus lEchmodns, from the Lias of Lyme Kegis," 

 by Professor Morris, F.G.S. (with a plate). In this paper Pro- 

 fessor Morris considers the genera Baiiedius, Jllclimodus, &c., and 

 discusses the characters upon which they are founded. These 

 Liassic fishes, with their tesselated surface of highly enamelled 

 black rhomboidal scales, form most striking objects among the 

 fossils of this singularly rich deposit, and, from the perfect state 

 in which they are frequently found, are sure to attract special 

 attention. 



5. Dr. Linnarsson's paper " On Fossils from the Eophyton 

 Sandstone of Sweden" is reproduced, together with the original 

 plates representing these singular bodies, believed by Dr. Torell 

 and some naturalists of eminence to be plant-remains, but of the 

 certainty of such determination rnuch doubt still exists ; they have 

 by others been considered worm-tracks and Trilobite-markings, &c. 

 Whatever their origin, they seem to be due to organic bodies, which 

 is, after all, the main point of interest. 



6. Professor Owen contributes a note on the occurrence of the 

 Elk with the Keindeer, &c., at Walthamstow, in Essex. 



7. Sir Phihp Egerton supphes a list of the Typical Fishes in 

 his collection at Oulton Park, which he states are open to inspec- 

 tion by all who take an interest in palaeontology.

 Valleys in Derbyshire."
