A phosphate ore from the Drymona-Epirus area (northwest Greece) was ground and sieved ( \(<40,40-63,63-125,125-250\), \(250-500\), and \(500-1000 \mu \mathrm{m}\) ). The particle fractions obtained were examined for their structure by XRD and for their specific surface area by \(\mathrm{N}_{2}\) ads

✦ Synopsis
Two independent approaches, the box counting and the sand box methods are used for the determinatiov of the generalized dimensions (Dq) associated with, the geometrical structure of growing deterministic fractals. We find that the muitifractal nature of the geometry results in an unusually slow convergence of the numerically calculated Dq's to their true values. Our study demonstrates that the above-mentioned two methods are equivalent only if the sand box method is applied with an averaging over randomly selected centres. In this case the latter approach provides better estimates of the generalized dimensions.

## Letters to the Editor The aim of this work is to determine the thermal expansion coefficient (a) of mono and polycrystalline graphite at low temperature. We think that the absence of a data in this temperature range is related to the weak sensitivity of the methods used and the difficulty in ge
