caught in the neighbourhood of Yarmouth,” there being no rivers 
in that part of England frequented by Salmonide. He says, “the 
fishermen begin to take these trout in the middle of April, and 
go on catching them to the latter part of July. The fishermen 
catch them near the shore from 3o to 130 yards from the beach. 
These trout exist in more or less abundance along the whole 
coast of Norfolk. They are migrating southwards. Their object, 
without doubt, is food, especially sand-eels and the fry of sea-fish, 
which are in abundance on the sands of the coast of Norfolk. 
These bull-trout must come from rivers flowing into the German 
Ocean to the north of Yarmouth.” He then enumerates these 
rivers, including the Tweed, and adds that he had “ come to the 
conclusion that the bull-trout caught on the Norfolk coast, are 
bred in one or other of these rivers.” (Report, p. 16.) 
That salmon migrate enormous distances is established by 
a fact communicated to the Tweed Commissioners by Dr. Giinther 
of the British Museum, that he knew “of an instance of a French 
sea-trout (now in the British Museum) being caught in the Bristol 
Channel.” (‘Salmonoids of the Tweed, Blackwood, Edinburgh, 
1867, p. 100.) 
In reference to two questions in my lecture, viz., the migration 
of salmon, and the deterioration of salmon in condition, whilst 
remaining long in fresh water, I here add some tables and notes 
taken from the Tweed Salmon Reports published by Blackwood, 
and also from some more recent reports by the River Super- 
intendent, not published, but communicated to the Tweed Com- 
missioners from time to time. 
These extracts also give definite information regarding the 
position in the scale of fish-life, of the “ orange-fins,” “ parr,” and 
© black-tails.”

r. Young fish, considered to be orange-fins, about 100 in 
number, were put into a pond at Carham, belonging to the late 
Richard Hodgson Huntley, Esq., in May, 1874, and were 
detained in it for five years, fed with bullock’s liver. 
These fish were from time to time examined by the Committee,
