Descriptions of sections in the cuttings of the three lines of the 

 Orleans Railway Company, from Paris to Bordeaux, Paris to A gen, and 

 Coutras to Brives. The study of the different beds of the Chalk tends 

 to show that the South-western Chalk Basin of France, connected with 

 the Ligerian Basin during the period of the Lower Chalk, gradually 

 became disconnected during the Middle Chalk period, and during the 

 formation of the Upper Chalk joined itself to the Pyrenean Basin. 

 These three divisions of the Chalk are: — Lower Chalk: 1. Iclitliyosar- 

 colite beds ; 2. Ammonite and Ostrcea marls. Middle Chalk : 3. Lime- 

 stone with Radiolites lumbricalis ; 4. Beds with Sjohcerulites radiosiis. 

 Upper Chalk: 5. Coniacien and Santonien ; 6. Carapanien; 7. Dor- 

 donien. G. A. L.

 inferred from a recent work by Brandt. F. W. R.

 The horizons of the Chalk recognized are : — in the White Micraster 

 Chalk, the zones of M. cor-anguinum and M. Leskei, and at the base the 

 various horizons of the Lezennes Chalk except the Thun ; in the Chalk 

 Marl, the zones of Terehratulina gracilis and Inoceramus labiatiis ; in 

 the glauconitic Chalk, the zone of Am. varians. At the base of the 

 system, at Lottinghen and Longfosse, the Gault occurs. G. A. L.
