The (Royal) Anthropological Institute, established in 1871 by the amalgamation of the Ethnological Society and the Anthropological Society, issued its Regulations in the same year and was incorporated under the Companies Acts of 1862 to 1886 on 26 Mar. 1886. It operated under the subsequent Acts of 1908 and 1929 to which amendments were made until 1962 when the RAI considered the adoption of new Articles of Association under the Companies Act of 1948. These were adopted as a special resolution at the Annual General Meeting on 27 June 1963. The By-laws were amended in 1973. Under the Acts annual returns to the Board of Trade were required giving name, nationality, usual residential address, business, occupation, lectureships, and date of birth of Officers, life Vice-Presidents, and members of Council, balance sheet, and auditor’s report; specimen signatures were also required.
