Experiment 2 shows again the decided contrast 

 between the winter alongshore and the summer offshore 

 migrations. The results are shewn on Chart II. by black 

 circles. Remembering that the lines connect the 

 station of liberation with the points of recapture of the 

 fishes, we see that the fishes recaught fall into two well- 

 marked groups — (1) a group of eight fishes recaught 

 within the first three months after liberation, that is 

 before the end of May, and (2) a group of five fishes 

 recaptured from five to ten months afterwards. The 

 former fishes were all recaught in the shallow waters in 

 Morecambe Bay and in the Bibble and Mersey Estuaries 

 by stake-nets, " tees " and second class trawlers ; while 

 the latter fishes were recaptured in relatively deep and 

 distinctively offshore waters by first class vessels. It 

 must be pointed out that the straight lines and arrow- 

 heads do not in this latter case represent the actual paths 

 followed by these fishes. Probably all those liberated 

 immediately moved into inshore waters, where some were 

 caught, and then after a sojourn there of two or three 

 months the remnant migrated offshore, where a further 

 proportion were recaptured. Two recaptures are not 

 shewn in the chart. One of the fishes was found off the 

 coast of Wexford, in Ireland, and the other on the 

 South Coast of Ireland. This latter fish had in two 

 months made a migration of, at the very least, 170 

 nautical miles. Two other fishes were caught offshore 

 (by steam trawlers) after ten months, but the exact locality 

 cannot be traced.
