laboratory. It is interesting to note that of the three researchers 

 at work during June and July one was a Frenchman from the 

 University of Nancy and another a Belgian from Louvain. 

 Since then we have had no one at work except our own staff. 

 The effect of the war upon the number of visitors to the 

 Aquarium was most striking. During the earlier part of the 

 Summer the numbers steadily increased beyond those of 

 previous years, and on Saturday, August 1st, the total was 

 1,054 in advance of that of the same date last year, but from 

 that time the numbers declined rapidly. During August, 

 which is usually our busiest month in the Aquarium, Port 

 Erin was, comparatively speaking, deserted, and our total 

 number of visitors for the year is now 12,031 — a decrease of 

 4,576 compared with 1913. The number of " Guides " to 

 the Aquarium sold to visitors is 657 — a decrease of 383 compared 

 with last year. 



It may be useful to students and others proposing to work 

 at Port Erin that the ground plan of the buildings showing 

 the laboratory and other accommodation should be inserted 

 here (see fig. 2, p. 23). 



In regard to the educational work in the laboratories, 

 the usual Easter vacation courses in Marine Biology were 

 carried on during April under the guidance of the teachers 

 in the Zoology and Botany departments of the University 

 of Liverpool. Other groups of senior students came in parties 

 or singly from at least a dozen Universities and Colleges. 

 For example, a group of nine senior students and teachers 

 led by Professor Cole came from University College, Reading, 

 and another nine in charge of Dr. Stuart Thomson from the 

 University of Manchester. A group of seven students from 

 University College, Nottingham, attended a course under 

 the direction of Mr. H. S. Holden, Lecturer in Botany. We 

 had two workers from the University of Birmingham, and other 

 Universities represented were Cambridge (including Newnham),
