It is nearly a century since chemists began to suspect the nature of the well known mineral usually distinguished by the name of Blende or Pseudo-Galena. Brandt, in 1735, showed that zinc was one of its constituents. In 1744, Funck demonstrated that it was an ore of zinc. Margraaff soon after actually extracted zinc from it. It was impossible to subject it to heat in an open vessel, without perceiving that it contained sulphur. But chemists did not succeed in their attempts to combine zinc and sulphur together. This led them to conclude, that in blende the zinc and sulphur were united together by the intervention of iron.

page 336 note * The premature death of this excellent young man, since this paper was written, is an event very much to be deplored. He had wrought as a practical chemist for several years in my laboratory; and, to much practical knowledge, had added so much neatness and dexterity, joined to uncommon industry, that he would certainly have speedily distinguished himself as a chemist.
