Iialleberg and Hunneberg in Siveden, and in many CI ^ AP - 
other parts of Europe, is entirely owing to v — v — « 
crystallization, which is equally displayed 
in the minutest and in the most majestic forms ; 
which, while it prescribes the shape of an 
emerald, or planes the surface of a mountain * 
does always tend to a regularity of structure, 
more or less perfect, in proportion as the laws 
of cohesion have been modified or interrupted by 
disturbing causes 5 . 
(2) Witness the remarkable result of crystallization exhibited by 
“ the Polished Mountain," near St. Bernard in the Alps, described by 
Saussure. The author visited this mountain in 1794, and observed, 
upon its polished surface, that striated appearancewhieh is visible upon 
the planes of any crystal, when examined w ith a lens. 
(3) The most eminent mineralogist of the present age considers the 
prismatic configuration of basaltes to be owing to a retreat : and with 
all deference to his great authority, it may be urged, that all crys- 
tallization is the result of a retreating fluid ; whether of the fluid 
matter of heat, or of any other, wherein solution has been effected.
