ResumoIn Hill's 1873 list of minor planets of the Hecuba group suitable for determination of the mass of Jupiter, (76) Freia has the largest coefficient for the long-period term in longitude. Observations consisted of 15 photographic plates taken at Heidelberg Observatory (1912-1933) and remeasured at the U. S. Naval Observatory, several plates remeasured at Lowell and Goethe Link Observatories, and 79 plates taken at the Naval Observatory (1947-1971). In addition, 43 visual observations taken at Berlin, Vienna, and Leipxig Observatories ( ) were reduced to the same catalogue system as the photo- graphic observations. Variational equations were integrated for the differential correction process. The derived reciprocal mass of Jupiter is 1047.366+0.007 (m.e.).
