In this bird the trachea enters the keel of the fternum in like 

 manner as in the Wild Swan j with this difference, that it is doubly 

 . reflected*, as may be feen by confulting the figure. As in the Wild 

 Swan, fo in the Crane, we find that both fexes have the fame con- 

 formation of parts, excepting that, in refpect to the Crane, the tra- 

 chea in the female does not pafs near {o far into the keel of it as in 

 the male, nor is the doubling nearly fo considerable. 



WE now pafs to birds in which the trachea enlarges in various 

 parts, efpecially juft at the angle of divarication, where it goes to 

 the lungs ; and which lafl circumftance, for want of a better name, 

 authors have agreed to call by the name of Ampulla, or Labyrinth, 

 as before obferved, p. 96. 



* To ufe the exprefiionof Dr. Parfons, « This may be compared to a French-horn, 

 " whereas that of the Wild Swan is ftraight within the bone, and may be compared to a 

 " Trumpet ; yet the entrance of this into the fternum and its exit, and its pafiage into the 

 " cavity of the thorax, are fimilar to thofe of the Wild Swan." See Phil Tranf. I. c.
