In the January Number of the Penn Monthly Dr. J. T. Rothrock, has an admirable article "on our weak ones." He shows that the prevalent recommendation of absolute rest, when people "feel bad" is a mistake. That even a step or two, or any little work is an advantage in cases of bad health. We are glad that this is the teaching of the highest thought in medical progress. A little greenhouse or even a few window plants may be the means of giving renewed strength in their case to "our weak ones".
