Revision of a report by the U.S. Bureau of Mines which described experiments performed in Pittsburgh, Pennsylvania to study mine gases. According to the foreword: "Much of the material is reprinted on the following pages in its original form, and changes have been made only where manifestly necessary. Laboratory methods have been brought up to date. Some types of apparatus described in Bulletin 42 have now become obsolete and newer designs are described instead" (p. 1).
