portion of crystals that fall are probably perfect 

 geometrical figures. This constant regard to equa- 

 lity in the form and size of the six radii of the 

 stellates ; the geometrical accuracy of the different 

 parts of the hexagons ; the beauty and precision of 

 the internal lines of the compound figures, with the 

 proper arrangement of any attendant ramifications, 

 and the general completion of the regular figure, — ^ 

 compose one of the most interesting features in the 

 Science of Crystallography.
