The present study investigates the notion that extragalactic redshifts are periodic in ranges around 24.2, 36.3, or 72.5 km/s for an independent sample of 89 nearby spirals, in the general field, with accurately determined heliocentric redshifts. A strong periodicity of about 37.2 km/s is found, against a white noise background, for an assumed solar vector coincidental, within the uncertainties, with that corresponding to the sun's probable motion around the Galactic Center. Comparison with sets of synthetic data simulating the overall characteristics of the real data show the periodicity to be present at a high confidence level. As an independent test, the sample was divided into two groups of 40 and 49 galaxies with more and less accurately determined redshifts, respectively. The measured strength of the periodicity is significantly greater for the group of 40 galaxies. The overall probability that the periodicity of 37.2 km/s arises by chance is in the range of 3 x 10 exp -6 and exp -4.
