VI PREFACE. 



the last paragraph, was reprinted in the Smithsonian 

 Eeport for 1862.* 



At first I only contemplated reprinting the papers 

 as they stood ; but having, at the request of the 

 managers, delivered at the Eoyal Institution a short 

 course of lectures on the Antiquity of Man, it was 

 thought desirable to introduce the substance of these, 

 so as to give the work a more complete character. 



My object has been to elucidate, as far as possible, 

 the principles of pre-historic archeology, laying spe- 

 cial stress upon the indications which it affords of the 

 condition of man in primeval times. The tumuli, or 

 burial-mounds, the peat-bogs of this and other coun- 

 tries, the Kjb'kkenmoddings or shell-mounds of Den- 

 mark, the Lake-habitations of Switzerland, the bone- 

 caves and the river-drift gravels, are here our principal 

 sources of information. 



In order to qualify myself, as far as possible, for 

 the task which I have undertaken, I have visited, not 

 only our three great museums in London, Dublin, 

 and Edinburgh, but also many on the Continent, as, 

 for instance, those at Copenhagen, Stockholm, Lund, 

 Flensburg, Aarhuus, Lausanne, Basle, Berne, Zurich, 



* The article on Cave-men was also translated in the Annales des 

 Sciences Naturelles, Fifth Ser. vol. ii., and that on North American 

 Archaeology in the Revue Archeologique for 1865.
