The comparative derivatogramms of the bones of the same human skeleton. Derivatographic analysis of bones coming from different periods of the same cemetery has been made by the author. The results ware nearly the same (Table 2.), however, the bones of the same cemetery, going back to different periods, have shown different losses in weight between 105° С and 580° С particularly as regards to the fraction between 380° С and 580° C. On this basis the relation of some bones to others can be befined, too, if the graves cannotbe separated with the help of grave furniture or burying rites.
