Table VIII.— Eighth Melting. 



In the eighth melting there appears to be no particular change from those 

 in the two last tables. The bars continue to retain their compact form, with 

 probably some slight increase in the densities of the exterior surfaces of the 

 bars. No perceptible change in the colour.
