The second part of the memoir (see Geological Recokd for 1875, 



p. 55). Maintains his position as regards the Carboniferous Limestone 



age of the Campigliese and Apuan Alps marbles. Compares these rocks 



with those similarly circumstanced in Algeria, Greece, the Pyrenees, 



the Montague Noire, the departments of Allier, Cautal, and Loire, 



Turkey and Asia Minor, Corsica, and the Tana^o Alps in Piedmont, and 



in most of these cases comes to the same conclusion. G. A. L.

 In this locality the Coal Measures lie regularly beneath reversed 

 Devonian beds. This has been explained in many ways. It is now 

 shown to be due to three great faults, known respectively as the " faille 

 du Midi " (southern fault), the " cran de retour," and the Boussu fault.
