ing" the parr to be the young of the salmon. Whatever, nevertheless, may be the 
result of their continuation, they will be of importance either as additions to the 
natural history of the young states of the salmon, or as elucidating the history of 
the true parr. It is impossible to detail the author's experiments without tran- 
scribing the whole paper; suffice it to say, that Mr Shaw considers that the young 
of the salmon remain in the river two years before migrating to the sea ; that 
they are during this period in the livery of the parr, and are known as such to 
anglers ; that during the April of the second year they commence to perfect their 
change to the livery of fry, the scales becoming silvery and easily deciduous, and 
that they begin their migration downwards so soon as this is completed. The 
experiments do not proceed beyond this period of their growth. Mr KING'S
