MAEINE BIOLOGICAL STATION AT POET EEIN. 37 



Mollusca Doris tuberculata, Acanthodoris pilosa and 

 Aplysia punctata (the sea hare) spawned freely. 



The basement floor of the aquarium was made use of 

 by Professor Boyce and Professor Herdman, during a 

 part of the summer, for some of their investigations on 

 the life conditions and health of the oyster, and the effects 

 of certain diseased conditions. Some further experiments 

 on the same subject are being made in these lower tanks 

 this winter ; and the place, from its constant coolness 

 and shade and its proximity to beach and sea, is proving 

 admirably suited for such a purpose. 



The Cueatoe. 



Mr. J. C. Sumner, from the Eoyal College of Science, 

 South Kensington, acted as Curator of the Biological 

 Station from March to November, and besides his 

 ordinary routine duties devoted much attention to 

 improving the stock of chemicals and fixing and preserving 

 re-agents in the laboratory. In his report to the Committee 

 he states " I made an inventory of everything in the 

 laboratory, all the apparatus, books, &c. ; and then made 

 a list of all the things I thought were wanted. These 

 have been brought or sent to the station from Liverpool 

 during the summer, so that now the place is really very 



well equipped the shelves contain all the necessary 



fixing and killing re-agents, together with some of the 

 commoner stains, &c." (For some faunistic notes from the 

 Curator's diary, see p. 79). The laboratory assistant, 

 William Bridson, is still in the employ of the Committee, 

 at a weekly wage, and continues to give satisfaction. 



Tempeeatuee of the Sea. 



The temperatures of sea and air have not been taken 

 with regularity through the season, but so far as the
