" A few additions have been made to the Library by 

 purchase and exchange, and have added materially to its 

 usefulness." 



The Aquarium. 



" In spite of an exceptionally rainy season, the 

 Aquarium has more than maintained its recognised 

 position amongst the chief attractions of the neighbour- 

 hood, over 15,500 visitors having paid for admission. Of 

 this number nearly 10,000 came in July and August, and 

 in the latter month 553 were admitted on one day. Not 

 without some difficulty during the busy months of the 

 spring and late summer the tanks have been maintained 

 in. good condition by the Assistant Curator. The only 

 addition to the fishes exhibited therein is the haddock, the 

 exceptional abundance of which in the neighbourhood 

 enabled us to secure a supply. The table tanks now 

 contain a really fine collection of anemones, as regards 

 both individuals and species, including the rarer forms, 

 Aureliana august a, Sagartia herdmani, Bunodes thallia, 

 and Stomphia churchice. Over one thousand copies of the 

 " Gruide to the Aquarium " have been sold, and the 

 applications for copies I have had from people at a 

 distance show that its usefulness is by no means confined 

 to our own institution." 



The Fish Hatchery. 

 " Our work in the Fish Hatchery has not been quite 

 so successful this year as last. The hatching season was 

 throughout marked by a high percentage of unfertilised 

 eggs, and the total number spawned was considerably 

 smaller than that of last year. Otherwise the work 

 progressed normally, and 3,460,500 larval plaice were 

 liberated between March 21st and May 10th inclusive,
