A summary of the mean direction and distance in each quadrant is shown in 

 the following table : — 



Distances travelled. — Eighteen of the fishes, or 33-3 per cent., of those about 

 which particulars exist, w^ere recaptured at distances not exceeding 10 miles from 

 the station, viz. 12 females (42-9 per cent.) and 7 males (26-9 per cent.). The 

 mean distance for the females was 5-9 miles, and for the males 5-5 miles. All 

 the females had moved to the south and w^est except one, which was got 10 miles 

 to the north and east ; of the males, 2 were got to the north, 1 north-west, 2 

 .south-west, and 1 south-east. Between 10 and 20 miles, 8 fishes were re- 

 captured (14-8 per cent.), 6 being males (23-1 per cent.) and 1 a female, the 

 average distance being 17-1 miles. Thus, 26 fishes (48-1 per cent.) were recap- 

 tured at distances not exceeding 20 miles, 13 being males (50 per cent.) and 13 

 females (46-4 per cent.). 



20 to 50 miles. — Thirteen (22-2 per cent.) w^ere recaptured at distances of from 

 20 to 50 miles, the average distance being 30-6 miles. Five were males and 8 

 were females (19-2 and 28-6 per cent, respectively of the total males and females 

 of which particulars were ascertained). 



50 to 100 miles. — Ten fishes (18-5 per cent.) were got, 4 males and 6 females, 

 the average distance for the former being 68 miles and for the latter 65-5 miles, and 

 the average distance for both combined was 66-7 miles. Theyw^ere all taken to the 

 north-east of the station. 



Over 100 miles. — Six (11-1 per cent.) were taken at distances exceeding 100 miles, 

 namely 5 males and 1 female. All had moved north and east, along the coast. 

 The distances migrated by the males were 101, 126, 155, 188, and 238 miles, the 

 average being 162 miles ; 2 were caught in the Moray Firth, 1 off KJnnaird
