and shows that animals were domesticated at a much earlier period than has hitherto been supposed. 
The lake-inhabitants of Switzerland cultivated several kinds of wheat and barley, the pea, the poppy for oil, and flax; and they possessed several domesticated animals; 
they 
had 
also commerce 
with other nations. 
All this clearly shows, as Heer has remarked, that they had at this early age progressed considerably in civilization; 
and this again implies a long-continued 
previous period of less advanced civilization, 
during which the domesticated animals, kept by the 
different tribes and 
in different districts, might have varied and given rise to distinct races. | 
Even if this latter fact were found more strictly and generally true than seems to me to be the case, what does it show, but that some of our breeds originated there, four or five thousand years ago?  But Mr. Horner's researches have rendered it in some degree probable that man sufficiently civilized to have manufactured pottery existed in the valley of the Nile thirteen or fourteen thousand years ago; and who will pretend to say how long before these ancient periods, savages, like those of Tierra del Fuego or Australia, who possess a semi-domestic dog, may not have existed in Egypt?| 1 blocks not present in  1859 1860 1861 1866; present in  1869 1872 |  | Since the discovery of flint tools or celts 
in the superficial formations in 
many parts of the world, all geologists believe that barbarian man existed at an enormously remote period; and we know that at the present day there is hardly a tribe so barbarous 
as not to have domesticated at least the dog. |
