THE full programme of the Aberdeen meeting of the British Association, to be held on September 5-12, should be now or shortly in the hands of members known to be attending. The programme itself forms only part of an unusually large bulk of literature issued in advance, for the local committee has prepared a handbook con taining full details of all the local arrangements, descriptions of the general excursions, and so forth. Should any members find themselves apt to Idse their way through all this niass of prelim inary information, there is no need for them to do so, if by using the summary time-table of the meeting they are able to decide what they wish to do with the opportunities offered; there are cross-references in the time-table to the appro priate pages in the handbook. The Scientific Survey of the city and district, also issued in advance, has expanded somewhat beyond the lines laid down in recent years, and may be thought to deal with one or two subjects outside the scientific scope; but its interest never fails, and these surveys, in the course of years, ought to grow into an extraordinarily valuable series. They have certainly no equivalent in other readily accessible form.
