Granton, Scotland. ° 
Tue Committee report that the sum of 1001. placed at their disposal has been 
expended in the maintenance and additional equipment of the Scottish 
Marine Station at Granton. The following report on the development 
and present condition of the station has been sent in to the secretary by 
Mr. J. T. Cunningham, the superintendent : 
At the time of the last meeting of the British Association the labora- 
tories and aquaria of the station were all contained in the floating esta- 
blishment called the ‘Ark.’ Last autumn more spacious premises were 
acquired. These are situated on the shore not far above high-water 
mark, and only a few hundred yards to the east of the submerged quarry 
in which the ark was moored. The property when acquired consisted 
of a number of rough brick sheds surrounding a central yard, and had 
been used as a factory; it covers an oblong area about 147 feet ina 
direction parallel to the shore, by 78 feet in breadth. On the north side 
of the area now stands the building containing the laboratory and 
aquarium, the former occupying the upper storey, the latter the ground 
floor. The laboratory is divided into two parts by a partition, the western 
room serving principally asa museum. The building was constructed 
and the laboratory fitted in the autumn of last year. In the spring of the 
present year the system of aquaria was fitted up, the work having been 
commenced at the beginning of May and finished on June 17. The 
aquarium tanks are seven in number, and are constructed of wood. A row 
of five runs along the north side of the aquarium room; these are 
shallow, their dimensions being 8 feet by 6 feet by 1 foot 3 inches. They 
are arranged in a stair-like series, each being about 8 inghes lower than 
its neighbour on the east side, and the water flows fromthe overflow-pipe 
of one to the other throughout the series. On the sotith side of the room 
are two deep tanks, each measuring 6 feet by 5 fe 
the front partially formed of plate-glass. 
The water to supply the aquarium tanks comes from a large reservoir, 
also of wood, fixed at a higher level than the roof of the aquarium room, 
in the shed to the east of the latter. The water overflowing from the 
aquarium tanks is delivered by means of indiarubber hose into a number 
of pits sunk into the ground; these are lined with cement, and roofed 
over in order to exclude dust and rain. They are situated at the west 
end of the central yard. 
The circulation of sea water is maintained by a horizontal double- 
action pump, which is fitted up in a small building at the south-east 
corner of the premises. A suction pipe two inches in diameter connects 
the pump with the quarry, and opposite the pits before referred to the 
pipe is fitted with a stop-cock and hose coupling, so that the communica-
