the lower extremity the ice becomes distinctly granu- 

 lated and composed of fragments, re-cemented as Agassiz 

 describes, and this structure may be traced at the very 

 edges, but not generally throughout the glacier. The 

 stratification becomes less apparent below, but is still 

 dearly traceable. It rises towards the wall of the 

 valley, whilst the whole middle, from leaning or falling 

 forward, appears to give a central horizontal stratifi- 

 cation ; but in reality these strata, as I believe, dip 

 inwards at a considerable angle. 



' In the upper part of the glacier yesterday we traced 

 vertical structure quite into the valley of the 

 Strahleck, near the lateral moraines, i.e. wherever 

 the ice is well formed, so that I ascribe its disappear- 

 ance or very imperfect formation in the centre, not 

 to the want of structure in the half-formed glacier or 



'', but to its incapacity of demonstrating it, there 

 being no formed strata of blue ice. We also traced 

 something of it in the glacier descending from the 

 Finster Aarhorn/ 



.Monday was a dies non, for the rain fell in tor- 

 rents, but Agassiz and Forbes faced the storm and 

 walked down the valley to Rosenlaui, devoting the next 

 day to a careful examination of the grooved and stri- 

 ated rocks in the neighbourhood of its beautiful glacier. 

 M Agassiz had effaced the polished surface with a 

 hammer within a triangular space close to the ice, in 

 order to see whether the advancing glacier would renew 

 presumed work; but they found that the ice had 

 1 at i his jmint so the experiment, with which 

 fi ajijH-.-irs ! have been much struck, was as yet 

 a failure. Tiny then walked hack to Imbuden, where 

 they fell in with Professor Guyot, of Neuchatel, and, 

 -what fatigued, patted the ni;ht at 

 'uyot was an intelligent companion, 

 and a great tea-drinker, while M. Agassiz gave them a 

 most ii .% history of his studies, and the develop- 



rs. So the evening pa 

 pleasant]
