CAPTAIX TUCKEY'S NARRATIVE. 41 



Mere any, were between E. N. E. and S. W., but mostly 

 southerW. Our only amusement now was the taking of 

 sharks, all of the white species ( carcharias ) , except one of 

 the blue (glaucus), and the only one seen during the pas- 

 sage ; the largest of the former was a male, ten feet long, 

 the latter a female impregnated, seven feet long; she was 

 unattended either b}^ pilot-fish or sucking-fish, while the 

 white sharks had many of both accompanying or at- 

 tached to them. It was observed of the pilot-fish (Gasto- 

 rosteus ductor), that they took especial care to keep out 

 of the way of the shark's mouth, generally playing over 

 the hinder part of his head. The shark was also observed 

 to lift the head above water and seize objects floating, with- 

 out any change of position. One shark was seen to leap 

 out of the water and seize a small albicore while it was itself 

 in pursuit of a flying-fish. 



The first bonitos (Scomber pe/amis) were seen on the 25th, 

 in latitude 5° 53., and many cavally or shipjack sported 

 after showers of rain, while flocks of tropic and other ocea- 

 nic birds hovered over the riplings they caused, in order to 

 seize the flying fish frightened from their element. 



On the 26th, in latitude 6° l6', longitude 13° 45', the tem- 

 perature of the sea at the depth of 220 feet was 64°, that of 

 the surface being 80°, and of the air 81".
