CEPHALOPODS. 313 



that when it rises from the deep it is in a 

 subverted shell, rendering that action more easy 

 and keeping the shell empty, but that when 

 arrived at the surface it reverses it; that it 

 spreads its sail to the wind, and when that 

 blows, letting down its two cirri, one on each 

 side, uses them to steer with. 



Upon comparing the animal of the nautilus 

 with that of the argonaut, it appears evident, 

 though the gills of the latter seem not to have 

 been examined, that they belong to different 

 Orders, at least, every probability rests on that 

 side ; yet every thing speaks the relationship of 

 the latter to the octopus, and therefore they 

 would properly form a section of the dibran- 

 chiata of Mr. Owen. In fact, the oral organs of 

 the former are so widely different from those of 

 the Order just mentioned, that one would 

 almost expect another to connect them. This 

 probably lies dormant amongst the fossil am- 

 monites, the shells of many of which, though 

 consisting of many chambers, are evidently in-

We must next inquire what was the object 

 of Him, who does nothing but with a view to 

 some useful, though not always evident, end, 

 in producing these miniature monsters of the 

 deep, so wonderfully organized and so unlike 

 every other tribe of animals, in his creation, and 

 yet containing in them, as we have seen, as it
