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 Kings 



temperature of quadrupeds, birds, fishes, plants, trees, and earth, as ascertained 

 at different times and places in Arctic America, during Captain Back's expedition,
