104 Study and Survey of British Vegetation. 
Highlands by Mr. F. J. Lewis’s latest memoir (Trans. Roy. Society 
Edinburgh : Vol. XLV.). 
Collection of Photographs. An excellent arrangement has been 
effected with the British Association Botanical Photographs 
Committee, whereby all botanical photographs collected either by 
that Committee or by this (the Survey) Committee may be con¬ 
sulted by anyone. The joint collection is to be lodged at University 
College, London for reference, while a duplicate collection, at 
Manchester and Cambridge will allow a selection of photographs 
to be borrowed by those who cannot consult the main one. A 
catalogue is in preparation for general distribution, which will be 
obtainable from Professor F. E. Weiss (University of Manchester) 
or Mr. A. G. Tansley (Botany School, Cambridge). Although still 
of course very incomplete, the collection includes many photographs 
of botanical subjects both at home and abroad. 
Publication of Maps. Means for improving vegetation maps 
frequently come under discussion, with the result that proposals 
are now under consideration which, if effected, will do much to 
remove the lack of uniformity in the maps hitherto published, and 
will considerably reduce delay in the issue of memoirs. 
Colour Scheme for Vegetation Maps. The progress of map 
surveys over fresh portions of Britain has led to the identification 
of new ecological groups not represented on the earlier maps and 
consequently not provided with distinguishing colours. The Com¬ 
mittee felt that it was desirable to use allied series of colours for 
vegetation series which were allied ecologically. After careful 
consideration to which several Members devoted much time, a 
scheme has been drawn up which has been adopted and will be 
published at a later date. 
It was also decided that further characteristic signs and symbols, 
and methods of hatching, stippling, &c., could profitably be utilized, 
and the Secretary was instructed to write to each member of the 
Committee for suggestions of this nature. 
Communications by members have become a distinguishing 
feature of the Meetings, and as these are followed in each case by 
discussion and criticism, they are of service both to the author and 
to his audience. It is natural that the Autumn Meeting, following 
on a season of out-door work, should produce the greater number 
of communications, and at Manchester a long list of observations 
and results was laid before a Meeting from which only two members
