Mollusca Doris tuberculata, Acantlwdoris 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

 of certain diseased conditions. Some further experiments 

 on the same subject are being made in these lower tanks

The Curator. 



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

 South Kensington, acted as Curator of the Biological 

 Station from March to November, and besides his

 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

 William Bridson, is still in the emplo}' of the Committee, 

 at a weekly wage, and continues to give satisfaction.
