all the stones proceed from the rock, even those in the clefts which 

 contain the breccia. 5. All the bones, properly ascertained, are those 

 of herbivorous animals. 6. The greatest number of them belong to 

 known animals, and even to animals still existing in those parts. 7. The 

 formation of these breccise, therefore, appear to be modern, in com- 

 parison with the great regular beds of stone, and with the alluvial beds 

 which contain the bones of unknown animals. 8. It is nevertheless still 

 ancient, with respect to us, since nothing shows that such brecciae are 

 formed at the present day ; and some of them, as those of Corsica, con- 

 tain also the remains of unknown animals. 9. The most striking cha- 

 racter which this phenomenon presents is rather the facility with which 

 certain rocks have been thus divided by clefts, than the matters with 

 which these clefts are filled. 10. This phenomenon is very different 

 from that which is yielded by the caverns of Germany, which contain 

 the bones of carnivorous animals only, spread on the ground, in a mould 

 partly earthy and partly animal ; although the nature of the rocks in 

 which these caverns are formed appear to be not very different from those 

 which contain the ossiferous brecciae." 



At Plate XX. Fig. 4, is the representation of a part of a jaw of some 

 ruminant, seemingly of a stag, imbedded in the reddish calcareous mass 

 of Gibraltar.
