to drive away tlie water, so that, by a process of exhaustion, it may 

 adhere with the firmness it is known to be capable of exerting, which 

 is so great tliat the strength of a man is scarcely sufficient to tear it 

 away. Even in death itself the close attachment continues, although 

 a sliding motion may without much difficulty loosen its hold. To the 

 fish itself this removal is easy, and is accomplished chiefly by an action 

 of the border, that permits a little water to pass among the attaching 

 laminae. From the drawing of a foreign species in my possession, I 

 am led to conclude that when the sucking apparatus is not in action, 

 the sides of the disk are capable of being brought together for the 

 purpose of covering and protecting the laminse of the disk.

It does not appear that when left to itself this fish is capable 

 of long continued or very rapid motion; and yet it is found to 

 be distributed over a wide extent of ocean, in regions where 

 the climate is sufficiently accommodated to its nature; but it has 

 not been met with northward of the temperate zone; beyond 

 which the water appears to be cold for its sensations. It is 

 said to be common in the Pacific Ocean, East and West Indies, 

 and on both sides of the Atlantic, as w^cU as in the Mediter- 

 ranean; although, at least in the sea last mentioned, it is 

 represented, as we have seen, to shun a near approach to the 

 land; a habit which, according to Hisso, has been accounted 

 for by supposing that it is influenced by dislike to the diluted 

 condition of the water, where a river pours its stream to mingle 

 Avith the Salter fluid of the deep. But whatever be the cause, 

 there is reason to think there is truth in the supposition that
