DUCK. 319 



The windpipe of the male is ten inches long, and has four enlarge- 

 ments, viz. one immediately below the mouth, another at the interval 

 of an inch, it then bends largely down the breast bone, to which it 

 adheres by two strong muscles, and has at this place a third expan- 

 sion : it then becomes flattened, and before it separates into the 

 lungs has a fourth enlargement, much greater than either of the 

 former, which is bony and round, puffing out from the left side.
