40 TRANSACTIONS LIVERPOOL BIOLOGICAL SOCIETY. 
deserted during the Summer, and our total number of visitors 
for the year is now a little over 1,500, in place of the 15,000 
we had in a recent season. The number of “Guides” to 
the Aquarium sold to visitors is only 88, compared with 
about 1,000 in a normal 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. 1, p. 41). 
In regard to the educational work in the laboratories, 
the usual Haster vacation course in Marine Biology was carried 
on during April with greatly reduced numbers. Although 
no members of the stafis of the Zoology and Botany depart- 
ments of the University of Liverpool were able, for various 
reasons, to visit Port Erin this year, a group of nine senior 
students of the University worked with great enthusiasm 
for about three weeks. The only other Universities represented 
were Cambridge (including Newnham), and the University 
of Manchester. | 
Work out at sea was wholly prevented, by Admiralty 
regulations, but collecting expeditions as usual, along the 
shore at low tide, were arranged in the Kaster vacation. During 
the remainder of the year the Curator and his staff made 
periodic collections from time to time as occasion offered, 
and plankton samples were taken across Port Erm Bay with 
regularity twice in each week throughout the year. 
As on previous occasions, the statistics as to the occupation 
of the “ Tables” during the year will first be given, then 
will follow the ‘“‘ Curator’s Report,’ and after that, as this 
year is the one-hundredth anniversary of the birth of Professor 
Edward Forbes, I have considered it appropriate to give a 
brief account of the work of that celebrated Manxman (see 
p. 53) for the information of our students and other workers 
at the laboratory.
