Kiszely, István: Derivatographic Research of Subfossile Bones

determination which concern the period where most of our archeological anthropological material belong. The author has been succeeded in clearing the optimal granulation, the quantity, the crucible, the choosing of time and the medium of calcination. Further, derivatographic analysis of calcinated bones has been started, and through this some informations can be gained about cremation. Derivatogramms of bones going back to different ages have given reassuring results about the estimative absolute age. Separation of bones of the same cemetery going back to different periods seems to be possible in a derivatographical way. Further results can be achieved by analyzing derivatographically the soil sample and the bone substance at the same time; and by fully analyzing chemically the bones at different degrees of heat. 224
