transmitted to us by Márta Sz. MATHÉ, the rest comprise a part of chips selected for hthic analyses by L. MACKEVOY from the Lvov Historical Museum, Transcarpathian Ukraine. All the samples of archaeological obsidian fitted conveniently into the category of Carpathian 1 obsidian on the basis of macroscopic features as well as chemical composition. In spite of the small number of specimens this is an important argument on the priority (if not exclusiveness) of the Carpathian obsidians already located; in the first place, the Slovakian variant. Sample LM 48 though resembling macroscopically to Carpathian 2 obsidians, proved to be silex, coloured by pyrite.

Thus, after changing the cathode, the spectra "slide" a bit, and the ratio values do change, as can be seen on comparing the data on the étalons measured on the same day after changing the cathode. Thus the rest of the material must be treated separately and compared with the spectra of étalons taken under the same conditions. The samples in this series come partly from archaeological sites excavated recently (Mogyorósbánya, Upper Palaeolithic, excavated by Viola DOBOSI and Csabdi, Lengyel culture, excavated by Judit ANTONI), partly from new material from the primary source of Mád—Kakashegy, surveyed together with Ernő MÁTYÁS of the Mád Ore- and Mineral Prospecting Co. The Mogyorósbánya pieces fit conveniently into group Carpathian 1, however, the 3 ' iteresting piece from Csabdi falls between Carpathian 1 and the Tolcsva variant of arpathian 2. It must be mentioned, however, that this piece was not cut and polished, and the measurements were performed on the surface of the sample only; this might modify the results (see measurement series 4, [30]). The extremely interesting lilac tint of the otherwise black nontransparent piece is unique in itself. Both in appearance as well as in chemical composition it reminds one more of the Tolcsva variant than the Slovakian ones. The Mád-Kakashegy pieces represent samples from the primary source of the C2E type, and completely agree with the etalon piece of the neighbouring Bodrogkeresztúr deposit.
