to the south-east, at distances of 16 and 24 miles ; 1, measuring 38-38-2 cm., 

 was described as " spent." 



In this quarter, 3 fishes, or 17"6 per cent., were recaptured. 



Second Quarter .—Three males and 2 females were got in September, 2 of the 

 males to the south and east, at distances of 28 and 33*5 miles ; the third male was 

 caught 12 miles to the north ; 1 of the females was recovered 27 miles to the south- 

 west, the other 51 miles to the north. 



In October, a female was taken 8 miles to the south-west ; it measured 45-45*3 

 cm., and is described as " spent." 



Two males were recaptured in November, one 29-| miles to the south and west, 

 the other 39 miles to the south and east. 



Thus, in this quarter, the number recovered was 8, or 47-1 per cent. 



Third Quarter. — In this period, only 1 fish was taken, namely, a female, in 

 February, after 239 days, in the Moray Firth ; it was got by a (lerman trawler, 

 and landed at Bremerhaven, and was stated to have been captured ]0| miles 

 N. I E. of CuUen, Banffshire, at a distance of 218 miles. No other fish was 

 recaptured within the first year after liberation, so that the total taken in the 12 

 months was 12, or 70*6 per cent., 6, or 50 per cent., to the south and east, 3, or 

 25 per ceJit., to the south and west, 2 to the north and west, and 1 to the north and 

 east. 



In July 1914, 2 males and a female were recovered. The female was taken at 

 a distance of 27 miles to the north and west ; 1 of the males was found in the 

 same direction, at a distance of 53 miles, and the other, 15 miles to the south- 

 west ; the latter, which measured 32-5-38*8 cm., was described as " spent."

The date of recapture of 1 of the fishes, a male, taken 26 miles to the south, 

 was not recorded. 



Dibtances travelled — 10 miles and under. — One fish, or 5*9 per cent., a female, 

 was got at 8 miles distant to the south and west. 



10 to 20 miles.- — Two fishes, or ITS per cent., a male and a female, went distances 

 of 15 and 16 miles respectively, the former to the south and west, and the latter 

 to the south and east of the station. 



Under 20 miles. — Thus, 3 fishes, or 17*7 per cent., went journeys of less than 

 20 miles, 2 to the south and west, and 1 to the south and east. 



20 to 50 miles. — Nine plaice, or 52-9 per cent., went distances of from 24 to 39 

 miles, namely, 5 males (62-5 per cent.) and 4 females (44-4 per cent.). Three of

 female to the south and west, and 1 female to the north and west. 



50 to 100 miles. — Two fish, or 11*8 per cent., were recaptured at distances of 

 between 50 and 100 miles, namely, a male, 53*5 miles to the north-west, and a 

 female, 51 miles to the north and east. 



Over 100 miles. — ^Three plaice (17"7 per cent.) wejit journeys of more than 100 

 miles, the average distance being 189 miles. A male and a female were got to the 

 north and west at, respectively, 121 and 218 miles distant, the latter being described 

 as captured in the Moray Firth. The other female went 228 miles to the south and 

 west, being taken off Flamborough.

 ripe." Another, of 32-5-38-8 cm., was taken at 15 miles distant, to the south- 

 west, in July 1914, and Avas said to be " spent." All the others were " immature."
