We find from experience that, when once a bottle of medicine gets itself introduced into a home, it never thinks of going out, but only goes on drawing other bottles in its train. We come across numberless human beings who are afflicted by some disease or other all through their lives in spite of their pathetic devotion to medicines. They are to-day under the treatment of this doctor, to-morrow of that. They spend all their life in a futile search after a doctor who will cure them for good. As the late Justice Stephen (who was for some time in India) said, it is really astonishing that drugs of which so little is known should be applied by doctors to bodies of which they know still less! Some of the greatest doctors of the West themselves have now come to hold this view.
