Acclimation of the Camel in Australia.—The introduction of 
the camel into Australia has been previously announced, and it 
was effected by the “Société d’Acclimatation.” We now learn 
that these animals have adapted peer ply to that country, as

Acelimation 2 the Salmon.—The eggs of the salmon which 
have been introduced into the waters of Australia have hatched 
and the young fish are prospering. Ice has been used in the 
transportation of the eggs, which, according to Mr. Youle, re- 
tards the phenomena of e embryonic evolution. This gentle- 
man has found that the vitality of the eggs may thus be pre- 
served for three or four months. It is in this manner that eggs 
taken from the Rhine at Huningen in Alsace have been success- 
fully transported to Australia. Sweden and Norway are both
