" The apportionment, by partition, of rather more than 

 half of the large store room above the fish hatchery to the 

 purposes of a chemical and physiological laboratory has afforded 

 Professor Moore and his assistants and other workers much 

 better facilities for their work on the nutrition of marine 

 animals and on the chemistry of sea-water. The work done 

 during the Easter vacation followed closely on the lines of 

 previous years. Collecting expeditions were organised to 

 various parts of the neighbouring coast, demonstrations of 

 oceanographic work were given on the S.Y. ' Runa,' and evening 

 lectures in the laboratory were taken by Professor Herdman, 

 Mr. Douglas Laurie and the Curator. 



" The number of visitors to the Aquarium during the 

 year — 16,607 — is a record one. It represents an advance upon 

 that of 1912 of about 2,400, and upon that of 1907, the highest 

 previous number, of about 1,000. One thousand and forty- two 

 copies of the new edition of the Guide to the Aquarium were 

 sold. This number also is substantially larger than that of any 

 previous year. 



" During the winter (November to March) the Curator has, 

 as in previous years, given frequent demonstrations and lantern 

 lectures on Nature Study and Marine Biology (1) to a class of 

 about 20 boys brought from the local Higher Education School, 

 and (2) to parties of children from the local and some other 

 insular schools. 



" The work of the fish hatchery was begun on Feb. 17th, 

 with 350 healthy plaice in the spawning ponds. The hatching 

 apparatus was set in motion with a first batch of 88,200 eggs ; 

 and by March 13th, when the first lot of larvae were ready for 

 liberation, the number of eggs incubating in the hatching boxes 

 was 2,344,000. Quantities of eggs exceeding half a million in 

 number were skimmed from the pond on March 18th and 31st, 

 and on April 8th and 11th respectively ; and upwards of 400,000 

 were collected on March 22nd and April 2nd respectively. On
