Table VIL— Seventh Melting. 



The general appearance of these irons is increased density in the fracture, 

 with finely granulated edges, and increased hardness at the corners. On 

 comparing these bars with those from the first and second meltings, an evi- 

 dent change has taken place in the closeness of the granulated structure and 

 increased hardness of the iron over the whole of the exterior surface of the 

 bars. Colour the same as the last. 



Results reduced to those of bars TOO in. square.
