updated than the Charter. Any revisions to the Charter or Byelaws require the approval of the Privy Council. Motto The design of the institute's Mycenaean lions medal and the Latin motto Usui civium, decori urbium has been attributed to Thomas Leverton Donaldson, who had been honorary secretary until 1839. The RIBA Guide to its Archive and History (Angela Mace,1986) records that the first official version of the badge of the Lion Gate at Mycenae was used as a bookplate for the institute's library and publications from 1835 to 1891, when it was redesigned by J. H. Metcalfe. It was again redesigned in 1931 by Eric Gill and in 1960 by Joan Hassall. The description in the 1837 by-laws was: "gules, two lions rampant guardant or, supporting a column marked with lines chevron, proper, all standing on a base of the same; a garter surrounding the whole with the inscription Institute of British Architects, anno salutis MDCCCXXXIV; above a mural crown proper, and beneath the motto Usui civium decori urbium ". The motto is translated "for the use of the people, for the glory of the city". Architectural education In the nineteenth and twentieth centuries the RIBA and its members had a leading part in the promotion of architectural education in the United Kingdom, including the establishment of the Architects' Registration Council of the United Kingdom (ARCUK) and the Board of Architectural Education under the Architects (Registration) Acts, 1931 to 1938. A member of the RIBA, Lionel Bailey Budden, then Associate Professor in the Liverpool University School of Architecture, had contributed the article on Architectural Education published in the fourteenth edition of the Encyclopædia Britannica (1929). His School, Liverpool, was one of the twenty schools named for the purpose of constituting the statutory Board of Architectural Education when the 1931 Act was passed. Soon after the passing of the 1931 Act, in the book published on the occasion of the institute's centenary celebration in 1934, Harry Barnes, FRIBA, Chairman of the Registration Committee, mentioned that ARCUK could not be a rival of any architectural association, least of all the RIBA, given the way ARCUK was constituted. Barnes commented that the Act's purpose was not protecting the architectural profession, and that the legitimate interests of the profession were best served by the (then) architectural associations in which some 80 per cent of those practising architecture were to be found.
