Tuberculous calcified foci of several stages of calcification were quantitatively analysed by internal standard method, using copper as the internal standard element and pure carbon powder as spectroscopic buffer.<BR>Results are discussed trying to explain the process of calcification. As the observed atomic abundance ratio shows, phosphorus is found so much in the earlier stage that it may surpass calcium: in the latter stage, however, phosphorus decreases to a half of calcium. It may be said that in the solid calcified foci of the latest stage, whole calcium is not always in the form of tertiary calcium phosphate.
