A PRETTY ORNAMENT FOR A BOY TO MAKE.
Dissolve in seven different tumblers containing warm water, half ounces of sulphates of iron, copper, zinc, soda, alumina, magnesia, and potash. Pour them all, when completely dissolved, into a large flat dish, and stir the whole with a glass rod or bit of broken glass for a while. Place the dish in a warm place where it will be free from dust and will not be shaken. After due evaporation has taken place, the whole will begin to shoot out into crystals. These will be of various colors and forms, some little ones being gathered together in small groups, and other larger ones scattered throughout the whole fluid. By a little careful study you will soon be able to distinguish each crystal separately, from its peculiar form and color, thus learning an interesting lesson in chemistry, while making a beautiful ornament for your room. Be sure and preserve it carefully from the dust.
