 how fish communicate with each other, and how this 

 female salmon seduced nine salmon to their ruin. 

 Examples of a similar kind are too often to be found 

 amongst the human race. 



It appears from the evidence, that the eggs remain 

 covered with the loose gravel for several weeks, and 

 they first show signs of life by a very slight fin, at
