Of the remaining 35 fish of the experiment, about which particulars are 

 known, 5, all females, were taken in December 1913, 1 of them 10 miles directly east, 

 and 2 to the south-west, 1 at a distance of 2 miles, and the other in the Firth of 

 Forth, at a distame of 43 miles. The retnaining 2 fish migrated north and east 

 for distances of 67 and 68 miles respectively. 



Twenty-six were got in 1914. Of 5 taken in January, 2 males and 3 females, 

 1 male was recaptured 16 miles to the north-west ; the remaining male and 3 females 

 were all taken ofi Banff, in the Moray Firth, at distances of 113 and 114 miles ; they 

 were "'nearly ripe." Four, 1 male and 3 females, were recaptured in February. 

 Tlie male and 2 of the females were taken north and east, the male at 16 miles 

 distant, and the females in the Moray Firth, at distances of 113 and 152 miles re- 

 spectively. The remaining female had migrated in a south-easterly direction for a 

 distance of 186 miles from the place of liberation, being found at Lat. 55° 14' N. ; 

 3° 4' E., which is a point about 158 miles east by south of N. Shields. These fish 

 were " spawning " or nearly ripe." In March, 1 male and 4 females were recaptured, 

 1 female 3 miles to the south and west, another, also a female, 97 miles to the south- 

 east, and the remaining fish to the north-east ; 1 along the coast of Aberdeen, 36 

 miles distant, and 2, a male and a female, in the Moray Firth, at distances of 139 

 and 145 miles. In April, 3 fish were taken, one male and 2 females ; the male was 

 caught 1| miles from the place of hberation, after 481 days, and was " ripe " ; one 

 of the fenaales was got 15 miles to the north and west, and the other ofi the coast of 

 Aberdeen, 64-|- miles to the north-east. Two females, taken in May, had moved to 

 the north-east ; one measuring 32-38-7 cm. was found only 7 miles distant, and the 

 other, got off the Fentland Skerries, 152 miles distant, was " spent." One fish, a 

 female, was caught in June. 10 miles to the east. Two were taken in July, a male 

 and a female, both to the north-east, one at a distance of 35 miles and the other at 

 29 miles. One male was caught in August 11 miles to the north-west, and another 

 in September, 71 miles to the north-east. One was taken in October 49 miles to 

 the north-east, and a female in December 7 miles to the south-east. 



Of the 4 caught in 1915, all were females, and the positions of recapture of 

 3 were ascertained. One was taken in January 15 miles to the north-west, 

 after 785 days. One was got in April, 29 miles to the north-west, uathin the Firth 

 of Forth, near the original place of capture. Tlie third fish was found in July, 

 after 965 days, off the coast of Aberdeen, 31 miles to the north-east of the station.
