of the 10-poltura silver coin with the date of 1706 cannot be excluded on the basis of the chemical analysis, but it cannot be verified by any document. The authenticity of the 4-poltura silver coin is very doubtful. óvári F.: III. Gondianus néhány antoninianusának vizsgálata metrológiai aspektusból (Metrological study on several antoniniani of the emperor Gordianus III) = Num. Közlöny 84-85, p. 167,(1986) (In Hungarian) 859 coins of known weight have been chosen from three large antoniniani hoards (Tulln, Smyrna and Singidunum) originating in the third century and the mean deviation has been calculated from the weight data of every type separately. The mean deviation of 646 coins minted in Rom is smaller than 0.40 g in every case, but the mean deviation of 213 coins minted in Antioch is larger than 0.40 g without exception. óvári F.: Ritka római antoninianusok a III. századból (Rare Roman antoniniani originating in the third century = Num. Közlöny 84-85, p. 31.(1986) (In Hungarian) Eighteen unpublished silver coins of the period 238-253 A.D. are described. They are as follows: 8 pieces from Gordianus III, 5 pieces from Philippus I, 2 pieces from Phihppus II and 1 piece each from Decius, Gallus and Volusianus. Besides the exact description of the coins also the weights, die axes, obverse and reverse legends are presented. The special features (hybrid or subaeratus or anomalies in the legend) and the alloy of the coins are mentioned too. Illustrations of every piece are presented.

Conf. on Spectral Analyis, Gödöllő, 1980, p. 265.(In Hungarian) Roman wall painting samples were investigated by optical emission spectroscopy. For the quantitative analysis home-made powder standards were used. On the basis of the data obtained a correlation between colours and main components was established.

(In Hungarian) Analysis of pigments from Roman wall-paintings was carried out by optical emission spectrometry. A low voltage D.C. arc source was used for excitation of the removed 5 mg samples which were mixed with graphite powder containing suitable additives. Three parallel 15 mg samples were necessary for the total qualitative analysis and for the determination of the concentration (with self-made standards) of some elements (AI, Cu, Fe, Mn, Pb, Ti, Zn) which were chosen as characteristic of the pigments.
