Aquarium. 



In the Aquarium one large new tank, with a front of one entire 

 sheet of plate glass, has been erected for fresh-water fishes, in which the 

 Loch Leven Trout, which have occupied it from the commencement, hnve 

 thriven surprisingly well. One of the larger sea-water tanks, which 

 broke down during the year, has been replaced by another of the same 

 dimensions, but with a continuous front of plate glass. 



An additional supply of water has been laid on from the main for the 

 fresh-water tanks, and for the purpose of driving with increased power 

 the aerating pumps for the salt-water tanks. 



A change in the manner of discharging the water into the fresh-water 

 tanks, namely, by bringing it through the bottom of the tank, instead 

 of, as formerly, running it in at the top, has proved a most beneficial 

 improvement. 



The following species have been exhibited alive during the year, those 

 with an asterisk being alive at the date of this report : —
