This is a preliminary report on a project in which I have been comparing observed and theoretical giant branch luminosity functions for a relatively large number of globular clusters. I believe that I have found some novel evidence to support significant He differences among globulars, especially for the inner part of the galaxy, where He appears to be increasing toward the galactic center.
