" The plaice hatching operations were conducted solely 

 by the Assistant Curator, Mr. T. N. Cregeen. 



Lobster Culture. 



" Owing largely to the want of an efficient boy assistant, 

 it was not found possible to carry on lobster culture on more 

 than experimental lines during the past season. Much of the 

 Curator's time had to be devoted to supervision of the 

 Aquarium ; and though the Assistant Curator devoted a large 

 proportion of his time to cultural work the results do not 

 compare favourably, numerically at least, with those of the 

 past two or three years. Female lobsters with nearly ripe 

 eggs were said to be exceptionally scarce this year, and only 

 5 were secured. These together yielded 3,857 larvae, 3,300 of 

 which were set free in the first stage, at various points where 

 suitable shelter is afforded ; 347 were transferred to the 

 larger plaice pond, and 200 to one of the smaller tanks in the 

 Aquarium, where they have been under daily observation.
