Trends of growth may, of course, be estimated by calculating the means of height and weight at each age, or weights for each height, irrespective of age, but many more children than are generally to be found in one school would be needed in order to arrive at a definite estimate. In the following a method is described by which the medical officer, without much labor and arithmetic, may easily test the trend in single schools
