Abstract
Translator's Note.βThe following paper was published as a report from the Chemical Laboratory of the Dutch Artillery School at Delft, where the practical details were elaborated. In a preface to the report the author expresses his indebtedness to Dr. D. W. Dijkstra, who suggested this method of air flow analysis (Chem. Weekblad 34, 351, 1937); to his collaborators, Dr. 6. Verkaaik and Dr. W. G. Perdok, and to the publication of Dr. A. Tasrnan (Chern. Weekblad.36, 534, 1939). I should also like to add my acknowledgments to Dr. Hoogeveen for his kind permission to publish the translation.
