The west wing constitutes the Fish Hatchery, access 

 to which is obtained through a door exactly opposite that 

 opening from the Aquarium into the Laboratory. The 

 dimensions are the same as those of the east wing, and the 

 ground floor is of concrete. Along the north or front wall 

 are ranged a series of eight hatching tanks, each of which 

 con tains a set of ten hatching boxes, of the pattern devised 

 by Captain Dannevig, of Norway, and similar to those used 

 by the Scottish Fishery Board and the Lancashire Sea- 

 Fisheries Committee. Floor space for four additional 

 tanks has been reserved along the south wall, the remain- 

 ing space being occupied by a concrete tank built on the 

 floor and measuring 10 feet by 5^ feet by 3 feet. A door 

 in the west wall affords access from the Hatchery to the 

 spawning pond, to be described below, while a wide double 

 door in the south wall opens into a passage, on the left of 

 which are a storeroom and lavatory, and on the right the 

 engine room and pump chamber. The engine is one of 

 Crossley Bros, well-known gas engines, and is of 3 horse- 

 power. The pump is of the three-throw vertical type, 

 built by 11k 1 same firm, and is capable of raising 4,000 

 gallons of water per hour. 



Eeturning now to the Aquarium, a spiral staircase 

 of iron at the north-east corner (fig. 10) affords 

 access to a spacious gallery, lighted from above and 

 by windows in the north and south walls. Around the 

 edge an ornamental balustrade of wood supports a -cries of 

 glazed desk cases for the exhibition of museum specimens. 

 Along the south wall is a bench of Canary white-wood, 

 with cupboards beneath for the storage of herbarium and 

 other specimens. Ample shelving accommodation for the 

 exhibition of spirit and dried specimens baa been provided 

 around tin- walls, while the front side of the srallerv forms 

 an apartment measuring :> >0 U*ci in length by over 10 feet
