FOSSIL EEMAINS OF MAN. 



I shall confine myself, in discussing this question, to 

 those fragmentary Human skulls from the caves of En- 

 gis in the valley of the Meuse, in Belgium, and of the 

 Neanderthal near Diisseldorf, the geological relations of 

 which have been examined with so much care by Sir 

 Charles Lyell ; upon whose high authority I shall take it 

 for granted, that the Engis skull belonged to a contempo- 

 rary of the Mammoth {Ele^has jprimigenius) and of the 

 woolly Hhinoceros {Rhinocerus tichorhinus)^ with the 

 bones of which it was found associated ; and that the 

 ^Neanderthal skull is of great, though uncertain, antiquity. 

 Whatever be the geological age of the latter skull, I con- 



Fi(5. 23.— The skull from the cave of Engis— viewed from the right side. One 

 half the size of nature, a glabella, h occipital protuberance, (a to 

 h glabello-occipital line), c auditory foramen.
