This experiment has been advantageously tried in England. Sulphuric acid was tried to be absorbed by infusible earth (Kieselguhr), and the solid form, which attracts moisture very quickly, has to be packed at once in lead-lined sheet iron vessels, and closed hermetically and soldered. It may be applied in solid form by putting it in contact with the carbonate and diluted by the addition of water, or it might be previously liquified by being placed together with water in lead-lined tanks. The high cost of transportation of the liquid acids may render the application of this solidified product convenient in far distant countries; but in this country it is most likely that manufacturers will not see any advantage to be derived from the use of this solid acid.
