Cliart I. shows the curves which ]iave thus been obtained, 

 and a certain amount of correlation is observable. Curves have 

 also been drawn for each month of the year, and a' similar 

 correlation is found in the months of March, April, May, June 

 and July, months during which it has been seen that the least 

 quantities are caught, and also in November. In August, the 

 catches are found to be greatest during the spring tides, and 

 least during the neap tides. In the other months no correlation 

 between tides and catches is to be seen. In order to obtain 

 reliable results in this connexion more data are necessary, 

 and statistics would be needed for a period of years before 

 coming to any conclusion as to the relationship between tides 

 and catches during each month of the year. 



Marking ExrEROiENT. — Professor Meek suggested that some 

 interesting facts might be obtained if a number of Norway 

 Lobsters were marked by punching out part of the telson. In 

 order to see if this would be detrimental to the creatures, two 

 were punched in the telson and also in the uropods, and two 

 months after the experiment they are still living and healthy. 



On 30th April, 1912, when on board the "Raider," 365 

 males and 200 females were marked and liberated from 12 to 

 14 miles to the east of Newbiggin. Notices have been distri- 

 buted amongst the fishermen and buyers at North Shields, and 

 through the kindness of the Fishery Board for Scotland and the 

 Board of Agriculture and Fisheries, to the fishery officers of 

 the east coast. The telson appears as here shown.
