A female, of 38-4ri cm., and "spent," was recovered in July, after 665 days, 

 15 miles to the westwards. 



In December, after 817 days, another female, of 35-5-46-2 cm., was taken, off 

 Noss Head, 128 miles to the north-east. 



One fish only was got in 1914. It was a female, of 40-5-48-2 cm., and " spawn- 

 ing," taken in February, after 897 days, near Aberdeen, at 52 miles distant to the 

 north and west. 



A summary of the mean distance and direction in each quadrant, travelled by 

 all the marked fish recaptured from this experiment, is given in the following 

 table : — 



Distances travelled — Under 10 miles — Four of the fish, or 6'9 per cent., were 

 recaptured at distances of from 2 to 10 miles, viz. 2 males (14*3 per cent.), with 

 an average of 5 miles, and 2 females (4'6 per cent.), with an average of 9-5 miles. 

 Two were found to the south and west, 1 to the east, and 1 to the west. 



10 to 20 miles. — Eleven, or 18"9 per cent., were got at distances of from 12 to 

 19 miles, viz. 3 males (21'4 per cent.), with an average of 14'3 miles, and 8 females 

 (18*6 per cent.), with an average of 15'6 miles. All the males and 3 of the females
