Belgium ; Mr. Allport writes on the Basaltic Kocks of tlio Midland 

 Coal-field ; The Kev. T. G. Bonney, on PMas-Burrows ; Mr. J. W. 

 Judd, on the use of the term Neocomian, &c, &c. There are also 

 the usual Geological Notices, Keports, &c. 



1 The Quarterly Journal of the Geological Society ' contains 

 papers by Messrs. E. Tate and J. S. Holden, on the iron ores asso- 

 ciated with Basalts in the North-east of Ireland ; Principal Dawson, 

 of Montreal, on the Structure of Sigillaria, and on some new 

 Animal-remains from the Carboniferous and Devonian of Canada. 



Mr. J. W. Hulke makes known a new Crocodilian skull from 

 Kinimeridge Bay, Dorset, which he has named Steneosaurus Man- 

 selii ; and some teeth associated with two fragments of jaw, from 

 the same, locality, which he has provisionally named Euthehiodon. 



Mr. Etheridge describes the Geological Position and the Geo- 

 graphical Distribution of the Beptilian or Dolomitic Conglomerate 

 of the Bristol area, from which were obtained the remains of Tlieco- 

 dontosaurus and Palseosaurus, Dinosaurian reptiles about which 

 more has yet to be made known. 



Mr. Wilson sketches out the surface-geology of Kugby, and 

 Mr. Lloyd does the same for the Avon and Severn Valleys. 



Mr. Moore's (postponed) paper upon Australian Mesozoic 

 Geology and Palaeontology, makes us acquainted with a large 

 number of new Australian fossils (chiefly obtained from erratic 

 blocks, of the parentage of which nothing is at present known). 

 These remains are, however, many of them very unsatisfactory for 

 purposes of determination. Mr. Moore considers they are com- 

 parable with our Lower Lias types. The part is a bulky one, and 

 is illustrated by nine 8vo and two 4to plates. 



The Ancient Relations of Land and Water. — Professor 

 Huxley's address last quarter to the Geological Society has 

 such vast importance for the zoologist that we must allude to 

 it here. It forms the starting-point of a scientific study which 

 hitherto has been suffering for want of some sound and com- 

 prehensive speculation to which workers may bring their facts, 

 which may be taken as the basis of operations, and enlarged, modi- 

 fied, and improved in various directions. The question suggested 

 by a consideration of the distribution of living organisms on the 

 earth's surface is, not only what forms have we in this or that 

 locality, but lioiv did they get there ? Did A come with B or with 

 C ; did they all come together or separately ? It is this examina- 

 tion of the faunae and floras of various regions which Professor 

 Huxley enters on, and broadly sketches out the various ways in 

 which in past times the terrestrial animals of the different areas at 

 present recognized may have arrived there. By fully following 

 out this line of study, we may one day be able to assign its proper 

 history to every species of animal and plant, and to trace the wan-
