The specific frequency, S, values of globular clusters in elliptical galaxies (S is the ratio between total (extrapolated) number, N(t), and absolute luminosity of the galaxy) depend on the adopted distance scale. If the distance is derived form the redshift with an assumed value of the Hubble ratio, h = H/100, then the optimum value of h may be derived for a sample of normal E galaxies covering a sufficient range of distances by finding the value of h which minimizes the dispersion. In this paper, the best consistency between the specific frequencies of globular clusters among nine normal E galaxies is reached for H = 85 +/- 4, where the error is evidently an internal error only. H = 85 is also the value that minimizes the mean specific frequency itself.
