10 TRANSACTIONS LIVERPOOL BIOLOGICAL SOCIETY. 



extending out towards Bradda Head, has many creeks 

 and good shore pools containing an abundant stock of 

 interesting animals belonging to various invertebrate 

 groups. 



The Biological Station is a substantially built, three 

 roomed house, measuring a little over 30 feet by 20 feet, 

 and standing on a solid stone and concrete platform, 

 which raises it about 10 feet above high tide. It has 

 windows looking out in three directions, north, south, and 

 west. The front door (see PI. IV.) leads into a short pas- 

 sage from which open to right and left tw^o small rooms 

 (6 and 7) which are used as the Director's room and 

 library and the Secretary's office, and will also be available 

 for the use of any members of the committee or any 

 special investigators who from the nature of their work 

 require a separate room where they can have privacy and 

 can set up delicate apparatus or leave their specimens in 

 safety. The secretary's office is also now being made light- 

 tight, and fitted with screens to the window so that it can 

 be used as a photographic dark room. 



Opposite the entrance is the door into the main labora- 

 tory, which measures about 22 ft. by 20 ft., and has 

 windows on both sides. In front of the windows run 

 strong fixed work-tables which will accommodate half a 

 dozen students with ease, ten at a pinch. So the 

 greatest number who can work in the station at one time 

 when crowded is a dozen, while half a dozen fill it com- 

 fortably. At the two ends of the main laboratory are 

 fire-place, sink, tables, closed cupboard, and abundance 

 of shelving ; while along the centre of the room runs a 

 strong table for small aquaria, and vessels containing 

 animals. A door in one corner opens into a useful small 

 yard between the house and the cliff, in which the concrete 

 fresh water cistern supplying the laboratory sink is placed,
