The two-point angular correlation function of galaxies is determined as a function of magnitude limit (i.e., depth) for the sample of galaxies in the Zwicky catalog. The observed scaling of the correlation function with depth is compared with that expected from the following models: the standard clustering model within a generally homogeneous medium; a pure fractal model; and a cell-fractal model. It is found that a pure fractal model is inconsistent with the data, in accord with previous observations. The homogeneous model and a cell-fractal model with an upper cut-off radius about 30/h Mpc are both consistent with the present data.
