Table VI.— Sixth Melting. 



The whole of the bars from the first up to the sixth meltings are soft, and 

 work freely under the file. The crystalline structure of those in the above 

 table exhibit a closely granulated texture round the edges and corners of the 

 bars, the same, or nearly so, as those in the last tables. 



Results reduced to those of bars 1*00 in. square.
