The sulphate of potash having been sub¬ mitted to a similar experiment with an equal weight of lime, and the dried residue having been treated with alcohol, an alkaline solution was produced ; and a part of the residue dis¬ solved in water, and yielded a small quantity of sulphate of lime along with the sulphate of potash. 3. One part of the oxalate of lime, and two of potash, having been kept in ebullition in a small quantity of water until the water was totally evaporated, and washed afterwards with a sufficient quantity of alcohol, to dis¬ solve the potash ; the residue, treated with water, and evaporated, yielded crystals, bear¬ ing all the characters of the oxalate of potash. 4. One part of oxalate of lime was boiled ta v - desic- / •
