We try to apply the cosmic crystallography method of Lehoucq, Lachieze-Rey, and Luminet to a universe model with closed spatial section of negative curvature. But the sharp peaks predicted for Einstein-de Sitter closed models do not appear in our hyperbolic example. So we turn to a variant of that method, by subtracting from the distribution of distances between images in the closed model, the similar distribution in Friedmann's open model. The result is a plot with much oscillation in small scales, modulated by a long wavelength quasi-sinusoidal pattern.
