The Lake-Dwellers of Switzerland). 149 



narrow rings, affected by waves of transversal displacement, 

 as well as of condensation and rarefaction. To obtain ocular 

 proof of the accuracy of this remarkable theory, to which so 

 much publicity has recently been given by the ingenious and 

 elaborate treatise of Mr. Proctor, may never perhaps be 

 granted to us ; we must not forget that even under the most 

 favourable circumstances, we have to contend with 700 millions 

 of miles of space ! It remains to be seen what may be effected 

 by persevering examination; hitherto it must be admitted that 

 instead of removing, it has increased the difficulties of the 

 subject. This will sufficiently appear from the ensuing part of 

 our prolonged recital, in which we shall see whether any in- 

 formation as to the structure of the rings, or indeed of the 

 ball, can be deduced from the appearance of their respective 

 shadows. The reader has already met with some puzzling 

 matter; he must now be prepared for statements still less 

 intelligible. 



So great is the variety presented to us in this marvellous 

 planetary system, that we are again obliged to postpone our 

 conclusion.

THE LAKE-DWELLERS OF SWITZERLAND.* 



In our fifth volume we published an interesting paper by Mr. 

 Henry Woodward, On the Ancient Lalce Habitations of Switzer- 

 land, and illustrated it by a plate containing a series of 

 drawings of implements and ornaments obtained from the 

 Swiss lake explorations, and now deposited in the British 

 Museum. We must refer our readers to that paper for general 

 views on the subject, and for sketches of objects belonging to 

 various dates. Our present purpose is to call attention to a 

 very valuable and beautiful work by Dr. Ferdinand Keller and 

 Dr. J. E. Lee. Dr. Keller is the author of a series of papers 

 on the lake dwellings, and Dr. Lee has, with his consent, 



* The LaJce-Dwellings of Sivitzerland, and otlier parts of JEurojpe. By Dr. 

 Ferdinand Keller, President of the Antiquarian Society at. Zurich. Translated 

 and arranged by John Edward Lep, F.S.A., F.G-.S. Author of " I*ca Silurium," 

 etc. Longmans.
