DELPHI1NUS BIDENS. 109 



it unites again, and passes on as one canal, but is very irregular on the 

 internal surface. 



The heart and lungs lie in the thorax, as in the brute ; but there are 

 no subdivisions [of that cavity] as in other animals. 



The stomach is lined with a pretty thick white coat, which seemed 

 to have no direction of fibres, but tore in any direction with ease. It 

 was corrugated by the muscular coat of the stomach. There is one 

 large and loose gut from the stomach to the anus. The rectum gets 

 behind the root of the penis, between the two cartilages contiguous to 

 the bulb and vasa deferentia, as in other animals. 



The liver is, as it were, half divided into two lobes, and in the fissure 

 passes the ligamentum rotundum, from thence passes up the falciform 

 ligament, as in the human. I could not observe any gall-bladder. 



The testes lie within the abdomen, just at the root of the penis, 

 where it enters the abdomen ; and the vasa deferentia pass backwards 

 to the root of the penis. 



There are two very large and long muscles that arise from what we 

 might call perineum, or union of the rectum with the bulb, &c, which 

 run over the bulb and acceleratores muscles, and continue along the 

 under surface of the penis. This muscle is similar to those muscles in 

 all those animals which retract the penis. 



Of the Bottle-Nose Whale [Delphinus {Hyperoodon) bidens, 



Cuv. 1 ]. 



The length of the animal, from the mouth to the end of the tail, 

 following the sweep of the external surface of the side, was 24 feet 

 9 inches. Round the body, at the thickest part, was 14 feet ; but pro- 

 bably it had swelled a foot or more ; however, probably not more, as it 

 is a skin which does not readily stretch. The tail at its extreme edge 

 was 6 feet wide. The posterior edge of the dorsal fin was about 1 foot 

 6 inches further forwards than the anus. The vulva was about 4 

 inches before the anus. The blowhole is of this shape w , and about 

 5 inches long, across the head 2 , and further back than the eye. The 

 opening of the eyelids is larger than that of an ox. The external 

 opening of the ear was about 5 inches behind the eye, and about an 

 inch or an inch and a half below the eye ; and its course inwards to 

 the skull through the soft parts was rather downwards *. 



* A worm was squeezed out at the external orifice.
