 42-5-44-3 cm., was taken, after 145 days, nearly at the same place, 29 miles distant.

 all being recaptured to the north and east.

 Aberdeen Bay, at a distance of 71 miles. 



Only 3 fishes were thus recaptured in the third quarter, all to the north and east.

 female, measuring 59-5 cm. on liberation, was recaptured in the Moray Firth off 

 Wliitehills, near Banff, at a distance of 137 miles, after 292 days ; its size on recap-

 where it was originally captured ; another male, of 29-5-35-5 cm., was got, after 

 299 days, to the east of the Isle of May, at a distance of 24 miles ; the third male,

In January 1913, 2 females were recaptured ; 1, measuring 41-5-44-3 cm., and 

 described as " spent," after 327 days, was taken off Buchanness, at a distance of 

 91 miles ; the other female, of 35-5-41-3 cm., was recaptured, after 307 days, in 

 the Moray Firth, off Noss Head, at a distance of 166 miles ; it was described as 

 " immature." 



Seven were got in February, 2 males and 5 females. One of the males, measuring 

 32-5-35 cm., and " spawning," was recaptured, after 357 days, at Aberdeen Bank, 

 at a distance of 72 miles ; the other male, of 30-5-36-6 cm., and " spawning " 

 (" partly spent ") was taken, after 352 days, in the same direction, at a distance of 

 62 miles. One female was taken in the Firth of Forth, off St. Monans, at a distance 

 of 4J miles, after 357 days; it measured 41-5-45-6 cm., and was "spent." The 

 other 4 females were caught off the coast of Aberdeen, 1 measuring 34-39-9 cm., 

 and " immature," after 358 days, near Buchanness, at a distance of 89 miles ; the 

 other 3 were got close together, at Aberdeen Bank, at distances of 72, 73, and 72 

 miles after respectively 353, 359, and 357 days ; they measured 40-5-46-2 cm., 

 39-5-47-7 cm., and 36-42-3 cm. ; the last-named fish was " spawning," and the 

 first 2 were " spent." 



Thirteen fishes, or 19-7 per cent., were, therefore, recaptured in the fourth 

 quarter ; 2 were got in the Firth of Forth, and all the others to the north and east, 

 except 1 which was found to the south and east. 



Thus, in the first 12 months after liberation, 39 of the fishes were recaptured, 

 or 59-1 per cent., the position of recapture of 37 being known ; twelve were taken 

 in the Firth of Forth. 



Of the remainder, 18 were got in the remaining months of 1913. In March, 

 2 males and a female were taken, all to the north ; tlie female, which measureci 30*5

 it was caught, after 363 days, off Buchanness, at a distance of 85 miles ; one of the 

 males, of 35-5-42 cm., was taken, after 374 days, to the east of the Orkney Isles,
