over into the absorber and back 10-15 times; allow the mercury to fall until KOH level returns to zero (this is accomplished by using the cock (C) to regulate rate of fall and the screw clip (S) for final fine adjustment); read the % CO, off the burette; repeat passage to check that absorption is complete. The analysis takes less than two minutes from start to finish. Accuracy.-Serial analyses are reproducible to within L 0.05%. Several comparisons both with the standard Haldane and with Lloyd's modification (Lloyd, 1958) gave agreement which was usually within ±0.05% and never outside 0.1 %. This degree of accuracy is more than adequate for the purpose for which the instrument is intended.
