The Species of the Oertus Argonauta are efreenied as fome of the 

 moft curious of the Tefiaceai,: whether we regard the manners of the 

 animals which inhabit theril, or the delicacy and elegant form 

 of their fliells. Like thofe of the Nautilus family, they fvvim 

 on the fur face of the wav^es, each fpreads a thin film for a fail, 

 and puts forth arms, three on each fide, which ferve for oars, in 

 which manner they glide along, but fiftk. inftantaneouily if but a 

 fhadow pafs over them. : The fti'iLidea. of the art of navigation- 

 is fuppofed to have been takefi from thefe little failors, and it is 

 to this family, one fpecies of which is certainly the Nautihis 

 of the ancients, that the famous Mr, Pope alludes, in thofe well- 

 known Hues of his " Efiay on Man," 



" Learn of the little Nautilus to fail, 

 " Spread the thin oar, and catch the driving gale." 

 The fliells of the Paper Sailor are not chambered, as the Nautili 

 xre, nor are they pearly within.
