of late years in tlie Silurian, Carboniferous, and Chalk rocliS has 

 amply demonstrated. 



After the description of each coast-section, the authors deal in 

 detail with the inland exposures, and collect together a mass of 

 information which should prove extremely valuable when a zonal 

 survey of Counties is undertaken. That this must come in the 

 near future is evident by a recent attempt by Mr. Jukes-Browne 

 himself to indicate the zones in the Chalk of Suffolk from fossils 

 collected in pits. In the description of the Norfolk coast, Mr. Jukes- 

 Browne establishes a new zone, the zone of Ostrea lunata, on the 

 collections of Messrs. C. Reid and K. M. Brydone : the results 

 obtained by the latter were published in 1900. It is comforting to 

 be reminded that there is a certain amount of this interesting zone 

 inland, as shown by the Well at Muudesley, since the northern 

 shore-mass of lunata Chalk at Ti'imingham is almost worn away. 



Chapter xxi. is devoted to - a sketch of the Upper Chalk of 

 France, wisely inserted for comT)arison. Chapter xxii. (pp. 302- 

 353), dealing with the microscoi)ical characters of the Chalk, by 

 Mr. Hill, is a summary, with additions, of his well-known papers on 

 the subject. The author is indebted to Mr. F. Chapman (now of 

 Melbourne) for determining the Foraminifera and Ostracoda (p. iv). 

 A discussion of the chemical composition of the Chalk occupies 

 Chai)tcr xxiii. (pp. 354-360). The bathymetric conditions and the 

 variations of the sea-bottom during the formation of the Upper 

 Chalk occupy Chapter xxiv. ; an account of the economic products, 

 Cliapter xxv. (pp. 379-402) ; of the physical features, Chapter xxvi. 

 (pp. 402-424) ; and of the water-supply from the Chalk, Chapter 

 sxvii. (pp. 425-440). One Appendix contains critical remarks on 

 some of the fossils, and gives a list of all the known fossils up from 

 the Upper Greensand (Selbornian) to the 0. lunata zone, with 

 careful indications of the zonal succession. Appendix II. gives a 

 full Bibliography of publications relating to the rocks and fossils of 

 the Upper Cretaceous Series of England. 



We congratulate the Officers of the Geological Survej'and Messrs. 

 Jukes-Browne and Hill on liaving completed a very laborious and 

 tedious task. We wish we could do the same for the printers. 

 The paper seems better than usual, but there appears to bo a difficulty 

 in keeping the type clean; while in two copies of this work that 

 we have seen the diagram at p. 206 is shorn of many of its letters. 

 There are a few editorial slips — -e. g., Pccten serrat at p. 12. Many 

 of the woodcuts are too antiquated for current books ; such new 

 ones as that on p. 26 are indeed a long way " after Howe " ; and it 

 is puzzling to distinguish in the picture at p. 91 the special layers of 

 Mint alluded to in the text.

Nowhere, perhaps, has the perfection of the camera and of i:>hoto-
