is ©Illy about 5 miles in a straight line, but almost double as far if the 

 sinuosities of the valley are followed. Between these extreme stations 

 lie, upon the right shore, those of the Madelaine, of Upper and Lower 

 Laugerie, of the Gorge d'Enfer ; on the left shore that of Cromagnou, 

 very near the Eyzies. (See map.)

Some of these are genuine caves ; others merely hollows in the rocks, 

 largely open to the valley. At the Moustier there is both a cave and a 

 hollow. The Gorge d'Enfer and the Eyzies are caves; the Madelaine, 

 the two Laugerie, and Cromagnon are hollows, but these distinctions 

 have no chronological importance. The most ancient troglodytes, as 

 well as the more recentj used both the cave and the hollow ; it is not 

 from the kind of habitation they occupied, but from the nature of their 

 remains, that we judge of their relative age.
