Abstract
The potential theoretic foundations proposed by Hardy for his multiqua dric-biharmonic method are shown to be either erroneous or deficient f or the purpose of gravity predictions based on mixed data types. Speci fically, the discretized model for the potential as a sum of point sou rces weighted by distance is nonharmonic in free space; whereas, the r elationships between gravitational quantities (gravity anomaly, geoid undulation, deflections of the vertical, etc.) are predicated on a New tonian (harmonic) potential.
