are now becoming recognized as true by many — perhaps the majo- 

 rity of geologists — more especially as respects the large part played 

 in these movements by the water contained in the interior heated 

 matter, which eventually, on its superficial coohng, forms the sub- 

 stance of all hypogene rocks. For entertaining this view, I was at 

 that early period subjected to much ridicule, and my arguments 

 generally disregarded." 



No better proof can be given of the value now set on the work 

 so long ago performed by this eminent geologist than the fact here 

 referred to, and the writings of Lyell, PhiUips, Forbes, and others, 

 testify how much they have themselves learned from this great 

 master. 



Professor Owen has an article* on the gigantic Beaver of 

 the Cromer Forest-bed (Trogontlierium Cuvieri), in which he 

 describes the femur, tibia, calcaneum, and dentition, maintaiuing 

 its j)osition and distinctive characters, as ijointed out by him in 

 1845. 



Mr. Woodward calls attention to the curvature of the tusks in 

 the Mammoth from Ilford, and compares it with the specimens m the 

 British Museum from Siberia and elsewhere, and shows clearly that 

 all the tusks of E. p"imigenius have, in aged individuals, a ten- 

 dency to curve inwards at their extremities. 



Mr. Carruthers describes some new Coniferous fruits t from the 

 Secondary rocks, also a new genus of Cycad from Scarborough.^ 



Messrs. Meek and Worthen have pubhshed in their 'Palaeon- 

 tology of Ilhnois' a most interesting series of Articulate Fossils 

 from the Coal-measui'es of Grundy County, Illinois. Commencing 

 with two new species of Phgllojioda, Geratiocaris sinuahis, and 

 Leaia tricarinata, they proceed to describe a new and very re- 

 markable form of Eurgjjterus (E. Mazonensls), very distinct from 

 those described by Hall, from the State of New York : a new 

 Limulus (Euproops Banse), nearly related to Prestwichia anthrax : 

 two new Isopods, AcantJiotelson Btimpsoni and A. Eveni. A third 

 form, Palxocaris typus, compared by Messrs. Meek and Worthen 

 with Gampsonyx fimhriatus, from the Trias, is by them referred 

 to the Decapoda-Macrura ; but its affinities appear to us far closer 

 with the 3Iysidw among the Stomapoda. 



They have found good evidence of Anthrapaliemon (a short- 

 tailed lobster), a species of which they name A. gracilis. Still 

 more interesting is it to learn that many remains of Insecia, 

 Arachnida, and Myriapoda, of the same age, have been met 

 with. They are — 1. Euphoheria armigera, a large species of 

 centipede, upwards of 4 inches in length, and preserved in a very
