IjlAA AN relates strange things of the affection 

 this species bears to its young ; among others, 

 he says, that it will permit the small brood, 

 when in danger, to swim down its mouth, and 

 take shelter in its belly. This fact has been 

 since confirmed by the observation of one of our 

 best ichthyologists,* and is no more incredible, 

 than that the young of the Opossum should seek 

 an asylum in the ventral pouch of its parent, a 

 fact too well known to be contested. But this 

 degree of care is not peculiar to the blue shark ; 

 it is we believe common to the whole genus. 



This species frequents many of our coasts, 

 but particularly those of Cornwall during the 

 pilchard season, and is at that time taken with 

 great iron hooks made on purpose.
