Densities of the three constituent spheroids of the same eccentricity as our earlier model of the Galaxy are assumed to be given by an analytical form of $_{{ ho}i}$(r)=$k_ie^{-m_ir^u{_i}}$, where $k_i,;m_i$, and ${alpha}i$ are obtained by comparing with the results of the previous model. Using three values of $_{{ ho}i}$(r) the galactic rotation curve, mass of each spheroid and the whole Galaxy are calculated, and the three dimensional density distribution in the Galaxy is also obtained. The calculated rotation curve of the model Galaxy is in good agreement with the observed curve, and the shape of the cross section of the model Galaxy given by the computed density is very similar to the inferred shape of the spiral galaxies.
