Of the others recaptured, 4 were taken in the remainder of 1913, 8 in 1914, and 

 1 in 1915. 



A male and a female were recaptured in October 1913, the male, of 31-34' I cm., 

 to the south and east of Aberdeen, at a distance of 42^ miles, and the female, of 

 33'5-39-9 cm., north of St. Abb's Head, at a distance of 36 miles to the south and 

 west. Two females were got in December, but the position of capture of 1 was not 

 ascertained ; the other, of 41-45 cm., was caught north-east of St. Abb's Head, at a 

 distance of 22 miles to the south and west. 



In January 1914, a male, of 35'5-40'2 cm., and " nearly ripe," was recovered 

 near Aberdeen Bank, at a distance of 29 miles to the north and west. A male and 

 a female were taken in Februarv, the male, measuring 36-42"7 cm., and " ripe," 

 south-east of the Isle of May, at a distance of 39 miles to the south and west ; the 

 female, of 33-36-2 cm., and " immature " was got in St. Andrews Bay, at a distance 

 of 54J miles to the north-west. Two females were recaptured in April, 1 of 39-50 

 cm., 17 miles to the notth and west, and " immature," the other, of 40-43 cm., in 

 the Moray Firth, off Lossiemouth, at a distance of 123 miles. In June, a male, of 

 36'5-41 cm., was taken, at a distance of 15^ miles to the south and west, and a 

 female, measuring 32'5-45'2 cm., 4-i miles in the same direction. In July, a male, 

 of 36-5-4r2 cm., was recovered north of the Bell Rock, at 37 miles distant to the 

 north and west. 



The last fish of the experiment to be recaptured was a male, of 33"5-42-l cm., 

 and " spawning," which was taken in March 1915, after 892 days, to the south-east 

 of Aberdeen, at a distance of 25 miles. 



A summary of the mean distance and direction in each quadrant, for the whole 

 experiment, is given in the following table : —
