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 Pl. IV.) leads into a short pas- 
sage from which open to right and left two small rooms 
(6 and 7) which are used as the Director’s room and

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 maim 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 
ereatest 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,
