There is a world of science necessary in choosing books. I have known some people in great sorrow fly to a novel, or the last light book in fashion. One might as well take a rose-draught for the plague! Light reading does not do when the heart is really heavy. I am told that Goethe, when he lost his son, took to study a science that was new to him. Ah! Goethe was a physician who knew what he was about.
