Ocean between Europe and America, 23 



The Shearwater . (Procellaria Puffinus, 

 Linn. J is another fea-bird, which we faw 

 every where on our voyage, from the chan- 

 nel to the American coafts ; it has much the 

 appearance and fize of the dark-grey Sea- 

 gull, or of a Duck ; it has a brown back, 

 and commonly a white ring round its neck, 

 and a peculiar flow way of flying. We 

 plainly faw fome of thefe birds feed on nm. 



The Tropic bird ( Phaeton cethereus, Linn.) 

 has very much the fhape of a gull, but two 

 very long feathers, which it has in its tail, 

 diftinguifh it enough from any other bird ; 

 its flight is often exceedingly high : the 

 firft of this kind we met, was at about for- 

 ty deg. north lat. and forty-nine Or fifty deg. 

 weft long, from London. 



Common Gulls (Larus canus, Linn. J we 

 faw, when we were oppofite the Land's 

 End, the moft wefterly cape of England, 

 and when according to our reckoning w r e 

 were oppofite Ireland. 



Terns (Sterna hirundo, Linn.) though 

 of a fomewhat darker colour than the com- 

 mon ones, we found after the forty-nrft. 

 deg. of north lat. and forty-feventh deg. 

 weft long, from London, very plentifully, 

 and fometimes in flocks of fome hundreds 3 

 fometimes they fettled, as if tired, on bur 

 fhip.
