NOTE.—The Manual of classification of patents, 1923, was issued by the Patent Office while it was under the Interior Department, so, although these corrections were issued by the Patent Office since it became subordinate to the Commerce Department, the old classification, I 23.2:C 56/4/923, is retained in order that the corrections may be filed with the publication to which they belong.
