SUMMARY It is described how inference concerning the geometrical structure of a two‐phase specimen may be carried out on the basis of sampling subregions or ‘quadrats’. Two basically different situations are considered—firstly when the specimen itself is the centre of interest, and secondly when the specimen is only part of a larger body of interest Weighted random quadrats are shown to be useful in the first case. Serial and multistage sectioning, and the incorporation of supplementary information via Monte Carlo techniques, are also discussed.
