It appeared highly prohable, horn the obfervations that oc- 

 curred in forging, and in the examination of the cake, that the 

 original proportion of mixture was fuch as would have formed 

 a qualit) of Heel fofler than No. 1 and 2 ; but as fteel of fuch 

 foftnefs requires a greater heat to fufe it, than when more 

 fully faturated with carbonaceous matter, it is probable that 

 the furnace had not been fiifficientlv powerful to occafion 

 complete fuiion of the whole mafs, and generate a fteel homo- 

 geneous in allJts parts.

Appearances on ^^^^^^ halves of this cake cut pleafanlly, and with a degree 

 forging the cake of tenacity and refiftance, mixed at the lame time with foft- 

 woo z, 0. 4. j^^|-^ beyond what was experienced in any of tlie former cakes, 

 i . Two quarters of this cake were drawn under the tilt hammer, 

 and one by hand. The refuUing bars were nearly perfe<5l.

which contained the figure. The fracture was foUd, though 

 jiot homogeneous as to quality and colour, and it appeared 

 pretty evident, that a confiderablj? portion of one fide through 

 the whole bar was in the liate of malleable iron, and of courfe 

 not capable of being hardened, Jt was a fubjedof confider-

y forging 5 th Cake. 



Appearances on T^^® fiffJ half'oif tills cake cut uncommonly foft for wootz, 

 iwging the cake but by cracking before the chiflel (lill exhibited » want of 

 •i woou, No. 5. proper tenacity. The next half cut equally foft, but with more 

 tenacity. Two quarters of this cake drew readily out under 

 the tilt hammer, and a third was drawn by hand at a bright 

 red, fometimes approaching to a faint white heat. None of 

 the bars thus obtained were uniformly free from cracks and 

 fcale, although th^ fracture exhibited a fair break of a light 

 blue colour, and^he grain was diftin^ly njarjLed, and free froni 

 ^olks. 



General Remarks. 

 Remarks. The formation of wootz appears to me to be in confequence
