XXTI. Experiments to ascertain u'hether there exists anj/ 

 Affinity betwixt Carbon and Clai/, Lime and Silex, se- 

 parateli/ or as Compounds united ivith the Oxide of Iron 

 formins; Iron Ores and Iron Sto?ies. By David Mushet, 

 Esq. of' the Calder Iron-PVbrks. 



[ComiiiueJ from p. 36.] 



W iTH a view to obtain results from ores compounded 

 similar to those which we use at furnaces in the scale of 

 manufacture, the four following classes \Vere carefully made 

 and operated upon : 



4th Class consisted of 



100 



As the details of these experiments might be deemed 

 t-edious, I shall contine myself merely to tables of the re- 

 sults obtained from tach compound respectively ; by which 

 it will be easily perceived that the peculiar properties of the 

 respective earths still exist where they are not corrected by 

 an equality of mixture, or where lime is not used as one of 

 the principal ingredients.
