					brecciæ. The bones which fill them some times present 
					characteristics sufficient to prove that they have,

					 There is a fifth race known, near Verona, whose

					Canada.(1) 
					 We also find in particular places, with the bones of 
					the rhinoceros and other quadrupeds of this epoch, 
					those of a deer so closely resembling the rein-deer, 
					that it is difficult to assign distinguishing characters to 
					it; and what is still more extraordinary, rein-deer are

					 There are in the layers of which we were speaking, 
					remains of a species very similar to the fallow-deer, 
					but a third larger,(3) and quantities of horns very
