They began, as we saw, by looking at the buildings. They then began to look at a great many children, and they saw that more than half of these children were not quite well, and that a great army of them were ill, and likely to be soon very much worse. And only last of all did they begin to see that learning, like eating, brings certain parts of the body into activity, and that one may learn something about the organ of thought as well as about the organs of digestion.
