    No. 41155.
    Protest 911161-G of R. W. Greeff & Co. (New York).
   Opinion by

Brown, J.

It appeared that the article called “iron by hydrogen” is the reduction of an oxide of iron by a jet of hydrogen leaving the element iron in powdered form with slight impurities, and that it is principally used for medicinal purposes. There was no proof in the record of its industrial use. The protest was therefore overruled. Mantle Lamp Co. v. United States (T. D. 48927) and Harrison Supply Co. v. United States (164 Fed. 155) distinguished.
