of the silver coins in the period from Gordianus III to Aemilianus, i.e. in the course of 15 years, decreased. Also the decreasing of the average silver content of the coins is demonstrated on the basis of chemical analysis of 402 antoniniani. The weight distribution curves of the coins of each emperor are presented. óvári F.: Gallus és Volusianus ezüstpénz verése (Silver coinage of the emperors Gallus and Volusianus) = Num. Közlöny 80-81, pp. 19-26.(1983) (In Hungarian) Empirical relations between the type variants and the number of the coins have been obtained from a detailed study based on the data of 35 coin hoards. In consequence of the distribution of the antoniniani according to the provinces and to the issues it is most likely that the 3rd issue dated in the RIC is earlier than the 2nd issue. This fact can be identified with the massive appearance of the coins of the mint of Viminacium in the Balkans. Exact statistical data are presented about the Antiochian coins of the emperors Gallus and Volusianus and a regularity is demonstrated concerning the distribution of the mint marks.

Magyar Színképelemző Vándorgyűlés, Miskolc 1981. jún. 15—18. Proc. pp. 11—14, (In Hungarian) An investigation on Roman coins was carried out by non-destructive laser-microspectral analysis. Recognition of the multiclassical system is introduced by means of hierarchic classification (dendrogram). For calssification of the unkf iwn samples the K-nearest neighbour method was used. A new mathematical equation was developed for the enhancement of the certainty of classification. Gegus, E. - Inczédy J. — Borszéki J. — Bakos M. — Óvári F.: Régészeti leletek összehasonlító vizsgálata a lézer-mikroszínképelemzési összetétel meghatározás alapján (Comparative Investigation of Archaeological hoards on the Base of Chemical Composition Determination Carried out by Laser Micro Spectral Analysis) = Industrial Achaeology II. MTA VEAB Veszprém, pp. 289-299 (1982) (In Hungarian) Spectrochemical analysis gives multielement information about the components of hoards characteristic for the origin of the material. In contrast with other radiation sources, the laser source permits a quasi-destructive investigation of metallic or nonconducting samples, logarithmic intensities of selected spectral lines measured in the laser spectra of the samples correlate with the content of the respective elements. The complex picture of the characteristic trace element contents contributes significantly to the identification of the hoards. By using a suitable computer program, pattern recognition methods make it possible to classify the hoards of various origin, and to decide ambiguous archeological or numismatic problems.
