tion of the thermoelement was less carefully adjusted, but the 

 relative position of the curves is clearly established. Figures 

 15 and 16 (Tables XI and XII) contain curves for the same

 (Tables XIII and XIV) for enstatite and the monoclinic 

 pyroxene, which represent the results of experiments made
