musical major scale is Fah, and the sixth is Lah. In short by 

 taking MendelejefFs table in the one hand and the major scale 

 of C in the other, turn to Felspar and Mica and take the 

 chemical analysis of these in some of the chemical works on 

 Mineralogy. We find Felspar composed of Potassium 39, the 

 first in the third octave ; Calcium 40, the second in that same 

 octave ; Aluminium 27, the third in the second octave ; Silicon 

 28, the fourth in the same octave; Oxygen 16, the sixth in the 

 first octave.

Mica is Potassium, Calcium, Aluminium, Silicon, Oxygen, 

 which correspond to the elements of Felspar, only they are 

 built in different proportions, and Magnesium 24 is added, so 

 the corresponding musical notes are much the same, only the 

 melody of the composition must be different. The Basalts are 

 much more complex than the Granites, and they are in great 

 variety. Here we have Augite, Felspar, Olivine, Leucite 

 Nepheline, &c, now in illustration take Augite ; Phillips gives 

 Silicon, Aluminium, Calcium, Magnesia, Iron, Manganese, and 

 Oxygen. Now Calcium 40 is the second in the third octave ; 

 and Magnesium the second in the second octave ; Aluminium 

 is the third in the same octave ; Silicon is the fourth in the 

 same octave ; Oxygen is the sixth in the first octave ; and 

 Manganese 55 is the seventh in the third octave.

These illustrations may suffice to shew the method by which 

 the notes of any crystal may be come at ; and these notes must 

 be composed into an air or built into chords, so as to feel the 

 harmony as well as the melody of the crystal, for the crystal 

 also is a composition. Thus we see the crystals of granite or 

 basalt and the scales or chords of music facing each other like 

 the two leaves of a book, so that we may gaze and listen to 

 the silent music of the still earth ; so deeply and intrinsically 

 does music enter into the hidden secrets and unvoiced harmony 

 of its rocky foundations. It is remarkable that such a substantial 

 thing as granite or basalt should have their crystals built of
