1G8 ZOOLOGY. 



fluke folded inwards. Its position in the womb was 

 that of a bent bow the head and tail being approxi- 

 mated, and the back arched. The umbilical cord 

 (which was inserted at the posterior part of the 

 abdomen) was five feet long, nine inches in circum- 

 ference, and chiefly composed of five capacious blood- 

 vessels. 



Of the bones of the neck, only the first, or Atlas, was 

 adapted for motion. The ribs were ten on each side ; 

 namely, five true ribs, and five false. The sternum 

 was composed of three pieces. 



The stomach was complex, and composed of four 

 cavities, or chambers. The intestines were very volu- 

 minous, destitute of a coecum, and, when extended, 

 measured 208 feet, or nearly fifteen times the entire 

 length of the whale. The trachea was broad and 

 flattened, and, soon after entering the chest, sent off 

 three branches, or bronchia, the third or accessory tube 

 (which was the smallest) entering the upper part of the 

 right lung, and the other two dividing, each into two 

 branches, previous to perforating their respective lungs. 



The spouting canal opened from the mouth by a 

 single orifice, which receives the larynx. After a short 

 course, in a vertical direction, it terminated in an 

 ample cavity, lined on its posterior wall by a dark 

 membrane, studded with flattened papilla?, whilst its 

 anterior boundary was smooth, and perforated by a 

 circular aperture. At this aperture the canal recom- 

 menced, and was continued to the superior extremity 

 of the snout, where it terminated in a second but 

 smaller cavity, immediately beneath the external nostril. 

 Between this last dilatation and the main tube, was 

 interposed a rigid valve, of crescentic form, and well 

 calculated to obstruct the passage between the cavity,
