PEREZ GEOLOGY OF NICE. O 



I insist then on the perfect agreement of these nummuUtic strata 

 amongst themselves (and especially with that containing zoophytes 

 and full of whitish fossils, which at the Croce di Mortola I described 

 as being unconformable by a local displacement), that these inferior 

 strata with Nummulites may not be dismembered, nor united with 

 the underlying cretaceous limestone [A.]. 



This order of the strata is repeated at the Fontana Giarrie with 

 the same fossils. 



The same succession is observable at Poggetto, Contes, Roccas- 

 terone, &c. ; places where I have collected — with MM. Bellardi, 

 Wandenhecke, Caillaud, Dr. Baudoin, Major Charters, and others — 

 more than a hundred species of fossils, the majority of which are 

 referable to supercretaceous forms, according to MM. Deshayes, 

 Defrance, Michehn, and Bellardi. At Blosasco Count Saisi of Nice 

 found a Nerinaa in the nummulitic strata ; and some cretaceous 

 fossils found in this terrain are noticed in Prof. Pilla's work ; but 

 their number is very small. 



At Braus only the stratum comparable to that above indicated 

 by No. 2 has been observed. More exact research, however, may 

 enable us to find the others also. I have there ascertained that the 

 nummulitic terrain reposes on the marly limestone with Inoceramus 

 quite unconformably, — a fact already noticed by Professor Sismonda, 

 and observed by him and Bellardi at Poggetto, Roccasterone, and 

 La Penne. 



The limestone with Lenticulites at Beaulieu ought to be collocated 

 with the nummulitic strata of Mortola, of which it represents the 

 strata marked No, 7. And in fact, if this be tertiary, as the Marquis 

 Pareto is inclined to think, with it ought to be arranged the num- 

 mulitic series of Mortola and of all the Maritime Alps, from which it 

 cannot be separated : — a fact proved by the marls that cover this 

 limestone, which abound with Foraminifera common to the num- 

 mulitic marls. 



A deposit, moreover, which I visited at the Torrent Lupo, in Pro- 

 vence, ought I think to be referred to the Alpine nummulitic terrain, 

 and should be regarded as analogous to the stratum marked No. 6, 

 both from the fossils which it contains, and from the nature of the 

 rocks which overlie it. In examining these rocks we find a con- 

 siderable development of marls and sandstones, which call to mind 

 the portions immediately above the nummulitic strata in other parts 

 of the Maritime Alps. Further, these sandstones are here covered 

 by Sub-Apennine tertiaries, with the usual development of bluish 

 marl and of conglomerate. 



Cretaceous rocks. — Without the intervention of the Hippurite- 

 limestone with Nummulites, the absence of which at Nice and on 

 the Ligurian coast has been demonstrated by M. Ewald, the 

 Alpine nummulitic terrain generally lies upon a marly limestone^ 

 sometimes full of green points, &c., the characters of which have 

 "been well described in detail by MM. Sismonda, Pareto, and others. 

 In this no Nummulites have been found ; but, on the contrary, 

 the following cretaceous species —
