[en] The Al to Mg abundance ratio is redetermined in two extreme metal-poor stars, HD 19445 and HD 140283, on the basis of accurate spectral material. It is found that: (1) one of the two lines used for the Al abundance determination is blended by CH lines; (2) no anomalous difference appears between the hotter and the cooler star, both showing an Al overdeficiency; (3) the observations are in fair agreement with predictions from the theory of explosive carbon burning.
