to decrease is j^erceptible, and small lemons, after some years of more 

 or less steady increase, now also show si<i;ns of diminution. But in 

 regard to turbot, haddock, and plaice, there is distinct evidence of 

 gradual diminution. In the case of tiu'bot this diminution is not 

 very conspicuous on the Northern grounds, but is marked both on 

 the East and West coasts. Large haddock have steadily and seriously 

 diminished. The decline in laige plaice has been great and con- 

 tinuous, and the decline in medium plaice, though not so great, is very 

 apparent on the Northern and Western grounds. Small plaice show 

 many fluctuations and have been of late abundant in some regions, 

 for instance on the Western grounds ; but elsewhere, and expecially on 

 the Eastern grounds, they also have shown a tendency to diminish.
