There was a physician in America who happened to think of this. Only, the difference is that when a scientist thinks of such a thing, even if it comes by intuition, he pursues it by going from the foot of the mountain towards the top. And it is very difficult to climb the mountain, and very often before he has climbed the mountain his life is ended. The physician is now dead. His was a very good idea. Although he had not come to the secret of it, yet as an idea it inspired many physicians in the United States and in the world, and it created great excitement in the medical world.
