Determination of firing distances fin German). Arbeitsmethoden der Karl Sellier, Schussentfernungsbestimmung, medizinischen und naturwissenschaftlichen Kriminalistik. Band 7. Herausgegeben von E. Weinig und S. Berg, Verlag Schmidt-Riimhild, Liibeck, F.R.G. 1988,116 pp. Every forensic pathologist needs basic knowledge on firearms and ballistics in order to be able to evaluate correctly a firearm injury. Sellier’s monograph is the standard book of reference in the German language. The first edition was published more than twenty years ago and the text has now been revised and brought up-to-date for the second edition. After a short introduction and historical review it provides the background to types of ammunition, powder-charges and bullets as well as the events during firing (Chapters I and II). The classification and characteristics of wounds, according to the firing distance, are briefly described in Chapter III, followed by the qualitative demonstration of gunshot wounds from an intermediate range of firing in Chapter IV. The morphological methods used for the determination of firing distances are reviewed in Chapter V, including IR-photography, chemical methods for staining discharge residues, autoradiography etc. The more sensitive methods based on quantitative analysis of discharge residues by emission spectrography, atomic absorption spectroscopy, neutron activation analysis and polarography are discussed in Chapter VI amongst other methods and possible sources of error, which have to be considered when using these methods, are considered. The last chapter (VII) concentrates on the investigation of firing distance determination of shotgun wounds. The book includes 61 photographs of good quality (3 in colourl, 14 tables, a list of 308 references and an index. It is written in a clear, compact and easily-readable manner and provides a good treatment and source of reference of this topic. P. Saukko
