When reviewing innovations of quantitative microscopy in the last 10–15 years, we find two striking trends: the construction of design-based stereological tools which enable the unbiased estimation of parameters, free from shape assumptions; and the connection of stereology with methods of stochastic geometry. Histological sections are stained thin slices through three-dimensional biological tissues that include collections of curvilinear features (muscle fibres, blood vessels,...), surfaces (cell membranes,...) and particles (cells, nuclei,...). The design-based tools provide unbiased estimates of the length, surface area and volume of these features per unit tissue volume, as well as unbiased estimates of the mean particle volume. The most prominent tool of this kind is the disector. When using stochastic geometry, we go a step further and try to explore the latent principles that might govern the manifest geometrical arrangement of the features. From the stochastic viewpoint, these are considered as spatial patterns of points, lines, surfaces or sets, generated by a random mechanism (in a wide sense). In contrast to a common prejudice which restricts stochasticity to the narrow concept of complete randomness, stochastic geometry offers a broad variety of well-defined alternative models, which allow, eg for attraction (clustering) and repulsion of features, and thus generation of fairly complex patterns. The linkage of stereology to stochastic geometry is enhanced by the increased availability of three-dimensional microscopy, such as confocal microscopes, which enable direct recording of coordinates (eg the coordinates of the centres of gravity of cells), that can be used for further data processing. Stochastic–geometric methods can be studied from original articles and textbooks for mathematicians, but these are widely scattered and often difficult to access by applied scientists. By combining rigour with understandable explanations and a multitude of examples, the monograph of Stoyan, Kendall and Mecke builds a bridge between the world of mathematics and microscopist who wants to incorporate a stochastic approach into a research project. The second edition which has now become available indicates the success of the first (1987). It is not just a reprint of the former, but includes new developments since 1987, insertion of new illustrations as well as edition of old figures, elimination of misprints and errors, and expansion of the References section (up to papers in press 1996).The book includes chapters on mathematical foundations of stochastic geometry, point processes, random closed sets, random measures, random processes of geometrical objects, fibre and surface processes, random tessellations (mosaics), and stereology. The chapters are largely self-contained; when embarking on a narrowly defined project (stereology of fibre processes, say), the reader may skip most of the book and concentrate on a few relevant sections. The chapters consist basically of an informal introduction and fundamental definitions, followed by a review of the main properties of the models and of statistical estimation methods. These are supplied with illustrations, worked examples from the applied sciences and hints for simulating the processes by computer. The relevant mathematical formulae are usually given without proofs, which greatly facilitates the fluency of reading; references to the proofs in the original articles are provided instead. Due to this property, the Stoyan/Kendall/Mecke has become a standard reference-book in the field, whose widespread use is evident from the references in papers on applied stochastic geometry. I am indebted to the textbook for providing …
