Essays concerning Iron and Steel ; the first, containing observations 

 on American sand-iron. The second, observations founded on 

 experiments on common iron-ore, with the method of reducing it 

 first into pig or sow-metal, and then into bar-iron ; on the sort of 

 iron proper to be converted into good steel, and the method of 

 refining that bar-steel by fusion, so as to render it fit for the more 

 curious purposes. With an account of Mr. Reaumur's method of 

 softening cast-iron, and an Appendix discovering a more perfect 

 method of charring pit-coal so as to render it a proper succedaneum 

 for charred wood-coal. London, 1773. pp. [vi]-223, i6mo.
