The 1935 Academic Costume Code was conservative and left most of the 1895 Intercollegiate Code intact, merely recording some of the specific details and practices that had been added to that Code by the 1910s, as well as the complete list of official Faculty colors the Intercollegiate Bureau had approved by 1935. Unfortunately, two inaccuracies crept into the final draft of this revision.
First, the Intercollegiate Bureau of Academic Costume stipulated that the edging of the hood and trimming of the doctoral gown (if not black) should be in a color distinctive of the “Faculty” of the degree as indicated by the wording of the diploma, not the “Faculty or subject” of the degree (see page 5 below under “Trimmings”) or the “subject” of the degree (page 6 under “Trimmings”). This imprecision in the 1935 text led to ambiguity regarding the proper Faculty color for so-called “tagged degrees”.
Second, on page 6 under “Linings”, single and multiple chevrons were not the only hood lining patterns used by the Intercollegiate Bureau of Academic Costume. In fact, the Bureau used many different kinds of heraldic patterns to divide the school colors in American hood linings.
