MAEINE BIOLOGICAL STATION AT PORT ERIN. 265 



Although this list is a somewhat shorter one than that 

 ill last year's record, still several of the workers stayed for 

 long periods, and so the amount of w^ork carried on in the 

 laboratory this year has probably been greater than in any 

 previous year. Some of this work will be referred to later 

 on in the report. 



Besides these workers, there were many visitors both 

 to the Laboratory and also to the Aquarium, which seems 

 increasing in popularity. During the season several 

 demonstrations on the animals living in the tanks were 

 given by the Director, and in September a special meet- 

 ing of the Isle of Man Natural History Society was held 

 at the Biological Station, when the Director gave an 

 address on " The Exploration of Our Coasts." 



The Aquarium. 

 A full account of the arrangement of the tanks and 

 pipes in the Aquarium-house w^as given in the last report. 

 Several minor additions and improvements have been 

 made during this year. High stands for small aquaria 

 and glass vessels have been erected in front of the 

 windows. The long table has been fitted with a leaden 

 covering, with upturned edges and w^aste pipe, so that 

 water spilled or leaking from aquaria may run off without 

 wetting the w^ood. New wall cases and shelving have 

 been added in the upper room for the reception of the 

 collection of Manks Marine Invertebrates (Echinoderms, 

 Zoophytes, Crustacea, and Mollusca) kindly presented by 

 Mr. G. W. Wood, and other similar dried or " spirit " 

 specimens collected in the neighbourhood. In this w^ay 

 the walls of the room are becoming covered with collec- 

 tions which form an interesting httle museum of local 

 marine zoology, and are a useful addition to the hving 

 animals in the tanks when explaining the results of our 

 dredging investigations to visitors.
