036 per cent of sulphur. The proposed method gives sulphur results about 0. 1 per cent lower than the peroxid method, the average of the 12 values which were lower by the proposed method would thus be about 0. 064 per cent less than by the absolute method. Both of these dis- crepancies are well within the experimental error. Also it should be noted that the difference between the figures obtained by fusing the barium sulphate in the peroxid method and reprecipitating, and those resulting from t...he first precipitation by the proposed method (as given in columns B and C, Table 1) varies from 0. 04 to -f 0. 11 per cent. In six out of twelve cases the figures obtained by the first pre- cipitation in the proposed method are nearer the values obtained by fusing and reprecipitating the barium sulphate in the peroxid method than they are to the results of the first precipitation in the peroxid method. The peroxid method gives a very high blank as compared to the proposed method; with the former this blank amounted to from 0.
