Reference to persons causing, procuring, aiding or assisting was omitted as unnecessary in view of definition of “principal” in section 2 of this title.
The punishment prescribed by section 545 of this title was inserted to make this section complete without reference to another section. In doing so it was necessary to rephrase the punishment provision of section 545 of this title, as originally enacted, without change of substance.

Changes were made in phraseology.
