 They are seen in small families or companies of six or eight in 

 the United States in winter, and frequent the sea-shores, lakes, 

 and rivers, continually diving in quest of their food, which con-

 swallowing a fish too large to enter whole into the stomach, 

 which therefore lodges in the oesophagus till the lower part is 

 digested, before the remainder can follow. The roughness of 

 the tongue, covered with incurved projections, and the form of
