“Salt is good."-S. Yark ix. 50.

THE servant of the great chemist he digs into the bowels of the earth, Berzelius was once approached by one and fashions the hidden treasures into of his countrymen with the question, bright ornaments and useful tools, or he " What is that chemistry, by which they transforms even the worthless sand and say your master has made himself so the shapeless clay into costly wares of famous ?” “I will tell you," was the brilliant splendor. But a few years pass ready answer. “First, I have to fetch away, and his beautiful handiwork all manner of things in large vessels; changes in shape and in color; a centhen he pours them into bottles, and at tury more, and they crumble into dust. last into quite small phials ; when he His magnificent temples, his lofty walls, has done that, he pours them all once his graceful bridges, his proud monumore into two big buckets, which I ments that were to give immo tality carry out and empty into the river. to his name and his deeds—they all That is chemistry."
