THE MARINE LABORATORY. 
In this report a photograph of the new laboratory is given, and 
plans of the two main floors. 
The laboratory occupies the site in Cullercoats harbour where 
the old baths building stood for so many years, and where also the 
first laboratory was situated. To ensure the site and the building 
being adequately protected, the quay was surrounded by a concrete 
wall built on the Hennibiquo system, and either resting on, or 
connected to, the rock by concrete piles. The foundations of the 
laboratory and tanks were also made of re-inforced concrete. The 
superstructure is of red brick relieved with sandstone. The roof 
is flat, and on the roof is a tank for storing the salt water for the 
laboratory taps, and projecting above it is a small third storey 
which provides lavatory accommodation, and also gives entrance to 
the laboratory by means of a gangway from near the top of the 
cliff. Behind the building the large storage tanks for the ground 
floor are placed, raised on concrete pillars, and beneath the tanks 
is the pump room, and by its side the boiler house. There are two 
boilers, one for heating the water for the taps of the laboratory, 
and the other for the radiators. The pump is a centrifugal one, and 
is driven by an electric motor. The building is lighted throughout 
by electric lights. 
Entrance is gained to the ground floor by doors at the front and 
back. At the front entrance is a small office, and the hall leads on 
one side to the public and on the other to the private aquarium. 
In the former there are eleven tanks around the room, lighted from 
above, and a floor tank. Access is gained to the side tanks by a 
gallery reached by a door leading from the first landing of the 
stair. The water is led to the bottom of the tanks by glass tubes, 
and drainage takes place at the top into a wide, straight tube in the 
partition wall. Each of these discharges into an open, deep and 
wide drain beneath the tanks. The tanks can also be sludged into 
this drain, which, when required may be made to discharge its 
contents outside the building. The floor tank occupies a large 
share of the floor space. It receives two supplies, one from the 
drain under the tanks just mentioned, and the other from a 
fountain. The floor tank discharges outside the building by way 
of a deep open channel in the floor. One advantage of the
