       NEW ELEMENTS FOR THREE ECLIPSING BINARIES


      At the Ege University Observatory we obtained from
April 1968 to August 1968 a great number of photoelectric
minima of eclipsing binaries. Some of the O-C's show large,
increasing O-C's against the elements in GCVS 1958 (I) and
SAC 38 (II).
      The new elements were calculated by the method of
least squares. These new elements were checked by later
minima which were not used for the calculation of these
elements.
