While there have been many changes in the details, the meaning of the various parts of the costume continues to be the same. Academic institutions in the United States adopted a code of academic dress in 1895 which has been revised from time to time. The dress of institutions in other countries varies consider-ably, but the basic elements are present in all academic costumes. GOWNS. The bachelor's gown has long, pointed sleeves; the master's gown has an oblong sleeve open at the wrists (or some older gowns may be open near the upper part of the arm); the doctor's gown is fuller than the others with velvet panels full length on the front and three velvet crossbars on each sleeve in black or in the color distinctive of the subject to which the owner's degree pertains. The gowns are always black except for the doctor's, which in a few instances is of a color representing the institution which conferred the degree. HOODS. The hood, draped over the shoulders and down the back, indicates the subject to which the degree pertains and the university that conferred the degree. The level of the degree is indicated by the size of the hood. The hood for the bachelor's degree is three feet long; for the master's it is three and one-half feet long; and for the doctor's it is four feet long. The binding of the hood is of colored velvet designating the subject of the degree, and it is two inches, three inches, and five inches wide for the bachelor's, master's and doctor's degrees respectively. The colors associated with some of the subjects are as follows: Arts, Letters, Humanities, White Commerce, Accountancy, Business, Drab Economics, Copper Education, Light Blue Engineering, Orange Fine Arts, including Architecture, Brown Law, Purple Pharmacy, Olive Green Philosophy, Dark Blue Public Administration, including Foreign Service, Peacock Blue Public Health, Salmon Pink Science, Golden Yellow Theology, Scarlet Medicine, Green The lining of the hood is of the color or colors of the institution conferring the de-gree. When two colors are used, they are usually arranged in a single chevion. The lining of the doctor's hood is revealed more than in the master's, and much less is revealed in the bachelor's hood. CAPS. In the United States, the black mortarboard is most commonly used. The tassel fastened to the center of the cap is normally worn in the left front quadrant of the cap and is black, although it may be of the color appropriate to the subject of the degree. The tassel for a doctor's cap may be of gold thread. 4 Candidates for Degrees BACHELOR OF SCIENCE Edward Allen Adler Baltimore, Maryland Physics Charles William Almquist Wiesbaden, Germany Engineering and Applied Science George Oscar Alverson North Little Rock, Arkansas Physics-English Bruce Allen Anderson Longview, Washington Engineering and Applied Science Lary Dale Andrews Wheat Ridge, Colorado Biology Dikran Antreasyan Istanbul, Turkey Physics Epifanio Anzaldo Tracy, California Chemistry Robert M.
