DURING most of the war years, the Stazione Zoologica at Naples was deprived of contact with the Allied Nations. As a consequence, the files of many scientific periodicals in its world-renowned library have been interrupted. The deficiencies are being made good as speedily as possible, but there is an inevitable time-lag. Friends of the Laboratory would therefore do a service to their science and a great personal kindness to present workers at the Aquarium by sending separate prints of recent publications to the Director, Dr. Dohrn. By so doing they would help to bring the library up to date and thus assist in the rehabilitation of this international research station.
