Text Appearing Before Image:
d of the seconddrying the cylinders which had been treated with the mixed solu-tion of sodium sulphate-magnesium sulphate and sodium chloride-magnesium sulphate were so badly cracked that the solution ranthrough the cracks without appreciably wetting the rest of thecylinder. The same thing occurred in the case of the single saltsolution of sodium sulphate and magnesium sulphate after thethird drying; with the mixed solution of magnesium chloride-magnesium sulphate and magnesium chloride-sodium sulphateafter the fourth drying; and with mixed salt of sodium chloride-sodium sulphate after the sixth drying. Following the seventhdrying the percolation was discontinued. By this time the sea-water cylinder was so badly clogged that the water would notpercolate through. While disconnecting it from the apparatus itwas overthrown and broke horizontally in two parts. All theother cylinders, except the ones treated with sodium carbonateand ferrous sulphate, as noted above, were cracked. In Fig. 1
