462 Renews — Keller's Swiss Lake- Dwellings. 



regular settlements, are the remains found so purely distinctive as 

 to enable us conclusively to attribute them to any one of the three 

 periods. The materials on which this division is based are mixed 

 to such a degree, that in nine cases out of ten the antiquary remains 

 imdecided as to what period of civilization he should assign a grave 

 or a settlement. An object very commonly both in form and 

 material bears the character of different periods : or it may be a 

 specimen useless in deciding the age, being found in settlements of 

 all the three periods. Thus the stone celt is an unsafe guide in 

 determining the period of civilization, though it strictly represents 

 the stone period, because it occurs in all stages of the bronze age, 

 and is not unfrequently found associated with iron weapons and in- 

 struments. 



" It is very certain that, at least in Switzerland, there was no 

 hard line of demarcation between the three periods, but that the new 

 materials were spread abroad like any other article of trade, and 

 that the more useful tools gradually superseded those of less value." 



Dr. Keller admits, however, the convenience of using these divi- 

 sions, when rightly understood, but he does not enforce them in a very 

 definite and rigid manner. 



The work contains a careful account of all the principal settle- 

 ments, their peculiarities of construction, and illustrations of the 

 most interesting remains foimd in each (1 to pp. 88). 



Dr. Keller then offers some general remarks as to the people of 

 the Pile-works, and their mode of life. He considers that the lake- 

 dwellings were all built by the descendants of the inhabitants of the 

 earlier dwelliugs, and not by successive peoples ; the better con- 

 struction of the later erections being due to the possession of better tools. 



A description is given of their woven fabrics ; of the plants and 

 seeds (by Dr. 0. Heer) ; of the animal remains (by Professor Eiiti- 

 meyer) ; and of the neighboui'ing mainland- settlements of Ebersberg 

 and three other places. 



An account is also given of other lake-dwellings not in Switzer- 

 land, and the Appendix contains some remarks on M. Troyon's 

 " Habitations Lacustres," and a notice of the latest discoveries ia the 

 Swiss lakes. 



No review, however complimentary, can do proper justice to so 

 laborious a work, both by Author and Translator — it must be seen 

 and read to be properly appreciated.
