ORDER GALLING. I67 



having died in a languishing state, and passed the latter 

 moments of its life without eating. The internal membrane 

 of the gizzard is very much wrinkled, very slightly adherent 

 to the nervous tunic, and of a corneous substance, or some- 

 thing very analogous to it. 



The crop, when inflated, is about the size of a tennis-ball. 

 The intermediate canal between the croD and ffizzard is of a 

 harder and whiter substance than that part of the intestinal 

 tube which precedes the crop, and does not exhibit nearly so 

 great a number of apparent vessels. 



The heart is more pointed than it is commonly found to 

 be in birds. The lungs are as usual. It has been remarked, 

 however, in some subjects, that on blowing into the trachea, 

 to put the lungs and air vessels in motion, that the pericar- 

 dium, which appears more loose than usual, became inflated 

 as well as the lungs. The trachea receives in the cavity of 

 the thorax two small muscular cords, about an inch long, and 

 two-thirds of a line broad, which are implanted there on each 

 side. 



These two muscles, adhering on one side to the bottom of 

 the trachea, and on the other to the clavicles, are peculiar to 

 all the species of gallinae. They serve to keep the trachea 

 fixed to the middle of the aperture of the thorax. The 

 lower part of the trachea, and the lower larynx of the Pin- 

 tados, difier much from these same parts in cocks and in 

 pheasants. In the pintados the entire tube of the trachea, 

 from the glottis to the distance of an inch from the lower 

 larynx, is formed of complete rings, in the intervals between 

 which are membranes. This part of the trachea is susceptible 

 of being elongated or shortened by two pair of muscles, which 

 accompany it through its whole length ; but at the distance of 

 an inch from the lower larynx the rings are broad, perfectly 

 cylindrical, and soldered as it were one upon the other. On 

 each side of this tube towards the lower part are five mem-
