The 19^<th> Sectional Committe of the Japan Society for The Promation of Scientific Research has made investigation on the methods for analysing gases in iron and steel since its foundation and has endeavoured to standardize such methods and devices. Previously the device for the analysis of nitrogen was completed and recently patented, and its method was published in Report No.1 of the 19^<th> Committee and is now commonly adopted in various places in this countoy. The analysis for oxygen may be classified in to three processes, viz., (1) residual process, (2) hydrogen reducing process, and (3) vacuum melting process. In future, the Committee is going to make investigation on the three processes, and at first the hydrogen reducing process has been deald with. On this process, the original scheme was proposed by Mr. Keijiro Kurokawa, and the method of taking specimens, the device and process were examined in the committee meetings which were opened several times. The same specimens extending over various kinds were specially made and sent to various places in order to receive the results of analysis by the proposed method. Finally, it was confirmed that all the results are in good conformity. The author is pleased to publish the method herein, which is the result oi the investigation continued for some four years.
