Report on the Work of the Marine Laboratory, Lame Harbour. 37 



Association, had successfully devoted himself to the Tunicata, a 

 group greatly neglected, but of much interest. Other members of 

 the Association had added to their lists of Crustacea, sponges, 

 Annelida, &c. New work of various kinds was next referred to. 

 Mussels had been dealt with by Dr. Carnwath, who studied those 

 found in Belfast Lough, and watched the changes in their bacterial 

 contents when removed to Larne. He found a rapid decline in 

 bacteria that indicated sewage contamination. His results had 

 been embodied in a paper that would soon be published. Dr. 

 John Milroy had undertaken a laborious investigation of the 

 glycogen present in oysters of different beds at different times of 

 the year. The object was to help in determining the time when 

 Irish oysters were in best condition. The Association had also 

 decided to make experiments in oyster-fattening on the lines of 

 work successfully carried out by the fisheries branch of the 

 Department of Agriculture elsewhere in Ireland. It was proposed 

 to lay down a number of small oysters in " caisses " to study their 

 growth, and ascertain if, as is probable, successful rearing could 

 be carried on in Larne Lough. The oysters experimented with 

 would be examined periodically by a chemist and a bacteriologist, 

 so that the fullest information might be available as to their 

 condition. Mr. W. H. Gallway had undertaken another important 

 addition to the economic work of the Association. He would 

 label a large number of fish and return them to the sea, so that if 

 they were recaptured something might be known of their migrations. 

 In Scotland and elsewhere such work had yielded valuable 

 information as to the definite and periodic movements. Another 

 new departure has been made by Mr. G. C. Gough, who was 

 engaged studying the bottom deposits from various parts of the 

 Irish coast. Samples taken by the dredge were sent by the 

 Department of Agriculture for examination, and Mr Gough was 

 thus enabled to engage in work that was alike of value to the 

 biologist and of interest to the geologist. The Association's 

 great object of ambition was a good laboratory, with an aquarium 

 attached. The value of the aquarium for educational purposes
