is undoubtedly older than the Coral Rag of the north, and also older 

 than the Alpine Coral Hag with Diceras LulcU. These conclusions are 

 directly opposed to those of M. Neumayr. G. A. L.

 The particular object is the determination of the position of the sand- 

 stones of Uchaux, in the Vaucluse. The evidence adduced for this 

 purpose is given under the following heads: — 1. Northern and eastern 

 portion of the Uchaux basin ; sections from the neighbourhoods of 

 Clansayes and Nyons are given here, and one of the region of the Mont 

 Ventoux. 2. The southern and western portion (by M. Toucas), with 

 sections from Orange to Lampourdier, from Salazac to St. Pancrace, and 

 from St. Pancrace to Bagnols. 3. Central portion of the basin (by 

 Messrs. Hebert and Toucas), with sections from Mondragon to BoUene, 

 from Mondragon to Piolenc, from Boncavail to Piolenc, from la Tala- 

 dette to Soumelongue, and from Noyeres to Bollene. 4. Resume and 

 conclusions (by Messrs. Hebert and Toucas). The general section of 

 Cretaceous rocks of the district is as follows : — first series Craie glau- 

 conieuse, in two divisions ; second series Uchauoc grits, with three divi- 

 sions, and Mornas grits ; third series sands and lignitiferous grits of 

 Polienc. 5. The Upper Cretaceous of Uchaux, compared with that of 

 the other Cretaceous basins of France. A table shows the equivalency 

 of the members of the basin of Uchaux with those of Southern Provence, 

 Aquitaine, Touraine, and of Northern France. G. A. L.

Naumann described the striated surfaces on the porphyry rocks at 



Hohburg, near Wurzen, in Saxony, and suggested that they might be 



due to glaciation. The present paper refutes this explanation, and 



maintains that these surfaces cannot be cited in proof of the continental 



glaciation of North Germany. They may be due to peculiarities of 



rock-structure, developed by the action of blown sand. F. W. R.

Calls attention to red breccias, composed of quartz fragments bound 



by a clayey paste, and to the presence on various points of the coast of 



Finistore of flint pebbles, which, the writer argues, point to the former 



presence of Chalk in the neighbourhood. G. A. L.
