Although the density and the rigidity distributions within the earth have been deduced from three different sources of data, - latitude. variation, earth tide and earthquake waves, - few attempt has so far been made to see whether or not these separate results agree with each other. In this paper, the writer has calculated what would be the latitude variation and the earth tide of that model earth whose internal constitution is such as suggested by seismic data. Both K. Bullen's density distribution and B. Gutenberg's velocity distribution of the earthquake waves were resorted to. The period of the latitude variation and the diminishing factor were numerically calculated for this model earth with the following results ; period factor k=0.270 diminishing factor γ=0.778 which are in a satisfactory agreement with the observed facts.
