M. Renoir on the Glaciers of the Vosgea. 289 



Mouthey in the Valais, of which I have spoken, and which cer- 

 tainly belong to ancient glaciers, are placed relatively to that 

 of the Rhone : that is in regard to the upper part of the val- 

 ley at the point where it turns. The same observation ap- 

 plies to those to be seen above Fellering and Oderen. 



Time and the nature of my engagements did not allow me 

 to explore again the part of the beautiful valley of the Moselle 

 which extends from St Maurice to Epinal and beyond it. Si- 

 tuate below the heights of Giromagny and Servance, I doubt 

 not but that it presents fine and numerous traces of extensive 

 glaciers, which it has for so long a time no doubt contained 

 on its sides. I have traversed it twice, but almost exclusive- 

 ly occupied with the study of crystalline rocks, I would not 

 afford sufficient attention to orographical appearances of the 

 nature of those which now occupy us ; so that my recollection 

 does not enable me to come to any conclusion regarding it. 

 I purpose next spring to study it in this new point of view, 

 and to give the result of my observations in the notice which 

 will accompany the topographical and geognostic chart of the 

 environs of Belfort, which I hope to be able to publish forth- 

 with. Meanwhile, Avhat we find concerning this valley under 

 the title of groupe des blocs erratiques, in the work of M. H. 

 Hogard on the Mountains of the Vosges,* allows us to dis- 

 cern, especially if provided with M. Rozef s good topographi- 

 cal and geognostic chart, the remains of terminal moraines in 

 those accumulations of stones in ancient lakes, and lateral mo- 

 raines in the deposits of pebbles and blocks lying at different 

 heights on the flanks of the valley, and even on the sides of the 

 neighbouring mountains, and which run in the direction of the 

 valley, and stop suddenly instead of descending to the lower de^ 

 clivities which are near them. This judicious observer rightly 

 judges that the hypothesis of the transportation of blocks of 

 stone by currents was inadmissible, for he says, in the article 

 on deposits in elevated places, p. 194 : — *' Besides sands, rolled 

 pebbles, and fragments of rock, composing these transported
