GENERAL VIEWS ON ARCHCEOLOGY. 313 



tion ; and the result obtained, however little positive and certain it 

 may appear, is assuredly much better than the total absence of any 

 data on the subject; and we must, therefore, be contented for the 

 present with this approximation, for the want of a better one. 1 



A third memoir with plates, by M. F. Keller, at Zurich, on the 

 lacustrine habitations will be published in the course of the month of 

 March, 18G0. It will contain a report in French on the lacustrine 

 habitations of Concise and the neighborhood of Yverdun, by M. Louis 

 Rochat; and another article, also in French, on the lacustrine habita- 

 tions of Estavayer, by Messrs. Rey and De Vevey. 



[In connection with this paper, which has been translated from a 

 pamphlet presented by the author, we may mention that Frederic 

 Troyon, of Switzerland, has also just presented to the Institution sev- 

 eral copies of a very interesting work on ancient and modern lacustrine 

 habitations. 2 This work gives a detailed account of the remains of 

 the ages of stone, bronze, and iron found on the site of ancient build- 

 ings erected on the borders of lakes in different parts of the world. 



After having collected and classified all the data relative to this 

 subject, the author gives a summary of the conclusions which have 

 been drawn from the facts. — Secretary Smithsonian Institution.] 



1 Objections against what has been said about the cone of the Tiniere have been raised in 

 the discussions of the "Societe Vaudoise des Science Naturelles." See the Bulletin of this 

 Society of the 16th of June, 1858. But the opponent not having thought it necessary to verify 

 the observations of the author, nor even to notice his numerical results, the latter considers 

 himself excused from answering, except by silence.
