THE preliminary programme and invitation circular for the eighty-ninth annual meeting of the British Association, to be held in Edinburgh on September 7–14, is now ready for distribution. Members of the Association will receive it shortly if it has not already reached them; others who propose to attend the meeting may obtain a copy on application to the Assistant Secretary of the Association, Burlington House, London, W.i. The circular, which is more comprehensive than has been customary, contains more than a merely preliminary programme, for many of the definitive arrangements for the meeting are set forth and a time-table of the principal engagements is appended. The circular is a pamphlet of sixteen pages with a three-leaf cover. One leaf, detachable at a perforation, provides two reply forms -one for intimation of attendance and the other for intimation of the member's local address-and, in order to assist the organisation of the meeting, members who propose to be present are requested to complete and return these forms at their earliest convenience. On another cover is a useful map of central Edinburgh, on which are indicated the principal buildings, especially those to be used for the meetings, the railway stations, the bus and tram routes, and the principal hotels.
