The experiments to devise means for impregnating water with carbonic acid gas or "fixed air," as it was first called, date back to the Eighteenth Century. Therefore in beginning this chapter on the soda-water machinery of the world, it may not be out of place to refer incidentally to those who were early engaged in experimenting with the newly discovered gas and the apparatus that was first made and used, both for experimental and commercial purposes.
