The results of several long series of latitude observations have been used for a separate determination of the coefficients of some nutational terms in obliquity and longitude.

The derived value of the constant of nutation is essentially smaller—and those of the coefficients of the semiannual and semimonthly terms larger—than the respective theoretical values, determined on the supposition that the earth as a whole is an elastic body. The theoretical value of the ratio of the axes of the nutational ellipse evidently does not need any correction.

On the basis of these data some conclusions of a qualitative character are made on the interaction between the core and the shell of the earth.
