EXPLANATION OF THE PLATES. 



Plate XX.

PLATES XXL XXIL XXIIL XXIV. 



Illustrate Mr. De la Beche's paper on Nice. 



Plate XXL 



Geological Map of the environs of Nice, and of the coast thence to Vintimiglia. 

 The dolomite and compact, light-coloured limestone are represented of one 

 colour, as they are so intermingled that they could not be separated without 

 rendering the Map confused. These rocks, together with the gypsum, are con- 

 sidered as an equivalent of some part of the oolite formation of England ; but 

 recent observations have shown that they may also be some modification of the

 reference to the oolite formation has been retained : p. 175. 



Plate XXIL 



A general view of the coast of the Mediterranean as seen from Mont Moron near 

 Nice: p. 171. 



Plate XXIIL 



Various sections, showing the relative positions of the compact limestone, dolomite 



with gypsum, the green sand, and the tertiary rocks.

Plate XXIV. 



Fig. 1. Natural section of the contact of the sub-Apennine clay-marl and rolled-pebble- 

 conglomerate in the valley of la Maddelaine (the conglomerate resting apparently 

 unconformable upon the clay-marl). There are two or three exhibitions of the 

 same nature in the neighbourhood. The more general character, at least on the
