Marine Biological Association of the 

 United Kingdom. 



Report of the Council, 1913. 



The Council and Officers. 



Four ordinary meetings of the Council were held during the year, 

 at which the average attendance was 11. A Committee of the Council 

 visited and inspected the Plymouth Laboratory. 



The Council has to record with regret the death of three of its 

 Vice-Presidents, Lord Avebury and Dr. A Giinther, who had been 

 connected with the Association since its foundation, and Sir John 

 Murray, as well as that of Professor Adam Sedgwick and of Dr. P. L. 

 Sclater, who were both members of the original Council and always 

 took a deep interest in the Association. 



The thanks of the Association are due to the Koyal Society and to 

 the Linnean Society, in whose rooms the meetings of the Council have 

 been held. 



The Plymouth Laboratory. 



No important repairs to the building were necessary during the 

 year. As regards the machinery, the small gas-engine which is used 

 for circulating sea-water through the tanks has been fitted with a new 

 piston and cylinder liner, and the arrangements for cooling the engine 

 have been altered. The pumps will soon require some attention, but 

 in other respects the machinery is in an efficient condition. The 

 circulation of sea-water through the tanks has been maintained 

 without any interruption. 



The Boats. 



The Oithona was put in commission in May, and has been working 

 continuously since that time. Mr. E. T. Browne having undertaken to 

 use the vessel in connection with his work on hydroids and medusa? 

 and to pay her expenses during a portion of the winter, the Council 

 has been able to keep the vessel in commission throughout the whole 

 year. This has been a very great advantage in many ways, especially
