the wind pipe. 
HIS elegant fpecies has been fufficiently defcribed before, as 
far as relates to external appearance; but the fingularity of the 
windpipe is, we believe, not fo generally known; it does not, as in 
the generality of birds, go ftrait forwards into the lungs, but firft 
enters a cavity inthe keel of the breaft-bone, for about three inches, 
when it returns, after making a bend forwards, and then paffes into 
the cheft *.
