lias acliieved a reasonable measure of success. There have been two 
informal meetings of the Committee with representatives of the Nature 
Conseivancy with whom we have worked in close collaboration. 
MAI’S COMMITTEE. Secretary: Prof. A. R. Clapham. 
Two meetings of this Committee have been held during the year. 
A consideiable amount of work has been done in the preparation of trial 
maps with a view to ascertaining the most practical and satisfactory 
method of presenting the data. It is expected that it will be possible to 
present a report to the next meeting of Council on proposals for the pre- 
paration of a series of distribution maps of British plants. 
ADVEBTISIJS' 0 COMMITTEE. Secretary: Mr. R. A. Graham. 
Dining 1952, 69 circulars have been sent to individuals likely to be 
interested in the work of the Society, and 20 new members and 5 institu- 
tions are believed to have joined as a sequel to the work of the Com- 
mittee. The number of circulars sent out has been greatly restricted 
owing to exhaustion of available lists of suitable botanists and institu- 
tions to approach. The Committee would welcome additional names of 
friends of members who would be glad to have details of the facilities 
offered by the Society. 
lEXCHANGE SECTION.

;tributor for 1952-53 and is now dealing with the plants contributed. 
The Council would like to express its appreciation of the services 
of members who have represented the Society at meetings of other 
organisations and at Public Enquiries during the year.
