Table IX. — Ninth Melting. 



The cohesive texture appears to increase, as the granulated surface of the 

 fracture in all the three bars seem to indicate. There is greater uniformity 

 in the crystals, which in these bars are very compact. No material change 

 in the colour, which is gray, with a slight tinge of blue. 



Results reduced to those of bars l"00in. square.
