Comparing calculated and exact values in an ideal example, it is shown that Peters' proposed method of downward continuation of gravity is far less suitable than a combination of Peters' procedure for upward continuation and a finite differences method for downward continuation. It is shown also how Peters' method can be substantially improved by considering only the closest values in the downward step of a continuation process.
