If we distinguish among the mountains those 

 which rise in detached masses, and form small 

 insulated systems (the groupes of the Canaries, 

 the Azores, the Sandwich Islands, the Monts 

 Dores, the Euganees), and those that make a 

 part of a continued chain (Himalaya, Alps, 



p. 23.) What characterizes the latter chain, is the relative 

 height of the summits (that is, the elevation of those sum- 

 mits compared with the top), which is much less in the Py- 

 renees, in the Andes, and in Himalaya ; for even in adopting 

 the measure of Dhawalagiri (4390 t.), we still find for the 

 Himalaya, only the relation of 1 : 1*7.
