ponds to the atmosphere in an analogous manner. It is oniy 

 the whole mass of the atmosphere which presents this beautifal 

 colour, to which we have assigned the characteristic name of 

 sky-blue, and to which different circumstances give a different 

 tint, the enamel-blue, the azure and the sea-green. It is re- 

 marked that certain glaciers exhibit certain particular tints, ana- 

 logous to those which the atmosphere presents in its different 

 modifications. The same parallel which we have shewn betweenf 

 we atmospheric fluid and water in a solid state, may be far* 

 ther established with water in a liquid state. Proportionally aS: 

 we ascend, passing from a glacier of the second kind to that of 

 the first, these varied tints disappear, and this latter assumes a 

 au|L^white, which has sometimes a feeble bluish tint. This 

 comparison of the two kinds of ^glaciers, under the relation o^ 

 tints, is not without use ; it demonstrates to us that the colour 

 increases from intenseness, whep we pass from a glacier of the 

 first kind, where the substance is strongly mixed with atmo- 

 spheric air, to that of the second kind, where it is more homoge- 

 neous. It is, then, to the presence of air in the ice that we may; 

 attribute these modifications; and it is not difficult to under4 

 stand how the ice, which contains much air, does not exhibit' 

 that transparency, that clearness, and that azure tint, which are; 

 peculiar tp that of the second kind, of which the formation is 

 more regular, and where the globules of air are either expelled^ 



or decomposed." r
