The feature of the two last quajters is the predoiviinant movement northwards ; 

 none was, in this period, recaptured south of the station. 



Of the 5 remaining fish of the experiment, 1 was taken in 1912, 3 in 1913, and 1 

 in 1916. A feniale, measuring 35-5-43-2 cm., was caught on 5th October 1912, j^fter 

 474 days, 12 miles to the north and east ; it was " about half ripe." In May 1913, 

 the fish whose sex was not ascertained was recaptured 26 miles to the north and 

 east, after 683 days. In July 1913, after 757 days, a male, measuring 36-41-8 cm., 

 \yas caught only 5 miles to the north and east, and in October 1913, after 837 days, 

 a female of 38-44*7 cm., was taken 17 niiles to the south and east, off St. Abb's 

 Head. Tlie female caught in October 1912 was described as "half ripe." In 

 June 1916, q,fter nearly 5 years of freedom, a female \yas caught 43 miles to the 

 north-east of the station. It measured 37-50-8 cm., but the condition of the repro- 

 ductive organs was not recorded.
