a line with a little convexity, rather than a protuberance. 

 Cuvier considers that the horns of the first species, which 

 Faujas attributed to a species of ox, belongs to the auroch ; 

 but this he does not appear to have established. The second 

 species is supposed, by Cuvier, to have belonged to that 

 wild race from which our present domesticated oxen pro- 

 ceeded. Pallas supposes a fossil skull, found in Siberia, to 

 have belonged to the common buffalo of India, or to a very 

 large species named amis; but Cuvier believes it to have 

 belonged to a species entirely different from the buffalo, the 

 amis, the ox, or the aurochs. Pallas also discovered a fossil 

 skull of another species in Siberia, which he believed to 

 belong to the musk-ox of Canada, an opinion in which Cuvier 

 concurs. 



It appears that the fossil ruminants belong to two orders 

 of alluvial deposits, and consequently to two different geolo- 

 gical epochs ; the one having been buried in an age distant 

 from the period in which we live, but the others at a far 

 more distant period : in that revolution in which the ele- 

 phants, rhinoceroses, mastodons, »1'C. inhabitants of the 

 torrid zone, were destroyed. 



It does not appear that the teeth of boars have been 

 found but in modern alluvial depositions, and no ways differ- 

 ing from those of the recent animals. 



Ossiferous hreccicR. — In the rock of Gibraltar, at Concud, 

 near Arragon, in the northern part of Corsica, in Dalmatia, 

 the islands of Cherso and Ossero, in several of the islets of 

 the Adriatic, on the northern shores of the Mediterranean, 

 and in many parts, several leagues distant from each other, 

 the solid rocks appear to have been split in different direc- 

 tions, but chiefly perpendicularly, and their fissures to have 

 been filled with fragments of calcareous rocks, and the bones 

 of various animals, lying in all directions, and most of them 

 bi'oken : sometimes mingled with the shells of snails and
