A STUDY OF PREHISTORIC ANTHROPOLOGY. 599 



bronze, and iron as have been found in Scandinavia. Other men took 

 up the investigation, and finally the opening of the canal between 

 Lakes Bienne, Neuchatel, and Morat not only brought to light the great 

 deposit of the iron age at La Tene, but so lowered the waters in the 

 two former lakes as to expose their shores, and to turn loose upon them 

 an army of seekers after the implements of prehistoric man. 



In 1859 was developed and acknowledged as genuine the discovery 

 of the paleolithic period, an earlier epoch in the existence of prehistoric 

 man. This was called at first the age of chipped stone, because the 

 implements were chipped or flaked, and not polished. This discovery 

 was made by M. Boucher de Perthes in the valley of the river Somme, 

 France. Thus there were found two kinds of stone implements — the 

 chipped and the polished — and from their respective positions it was 

 concluded that they belonged to two different races of men occupying 

 the country at different and perhaps remote periods of time, in which 

 the earlier chipped the stone to make his impalements, while the other 

 had so increased his knowledge as to be able to polish them. These 

 different periods were named by Sir John Lubbock paleolithic, meaning 

 ancient stone; and neolithic, recent stone. From that moment prehis- 

 toric anthropology received an impetus proportionate to its importance, 

 and since then has gradually elevated its rank among the sciences. 



BIBLIOGRAPHY. 



Prehistoric anthropology is a new science, and although its bibliog- 

 raphy is not extensive, it has attracted much public attention and many 

 books have been written in later years. These have either been of a. 

 popular character or else have related to a particular epoch or a single 

 locality. Ko complete or standard work has yet been j)ublished, either 

 in Europe or America. Professor Worsaae, of Copenhagen, contem- 

 plated such a work, of which Hon. Rasmus Anderson, United States 

 minister to Denmark, was to have been the English translator. But Pro- 

 fessor Worsaae's death prevented the carrying out of this undertaking. 



Monsieur de Mortillet published "Le Prehistorique," which, with its 

 album of illustrations, has become a standard work for the age of stone 

 in France. He now has in press a work to be called " The Protohisto- 

 rique or the Aurora of History." 



MM. de Quatrefages and Hamy have now under way a work to 

 be entitled "Histoire Generale des Races Humaines," to be published 

 by the ethnologic library, but of which there has, as yet, been issued 

 only the introduction by M. de Quatrefages; and "The Aztecs," by 

 M. Lucien Biart. 



Dr. D. G. Brinton, professor of ethnology and archaeology in the 

 Academy of Natural Sciences of Philadelphia, has edited the portions 

 of the "Iconographic Encyclopedia" which relate to anthropology, 

 ethnology, and ethnography. The articles on the two former subjects 

 were prepared by Dr. Brinton, and the latter was translated from the 

 German of Georg K. 0. Gerland.
