PIGEON. 



I. External Characters. 



1. Note the shape of the head, the neck, the 



trunk, and the tail. 



2. Note the arrangement of feathers in the body, 



the wing, and the tail. Pull out some of 

 each of the different kinds and keep them 

 for examination. 



3. Sketch the head. How many openings ? Com- 



pare with those of the frog. 



4. Observe the different parts of the wing and 



of the leg. Find the hand and the foot. 

 Note the attachment of the feathers. "What 

 forms the covering of the foot ? 



5. Pluck. 



(This can be done more easily if the skin of the 

 bird is first thoroughly wet with very hot 

 water. Great care should be taken when 

 pulling out feathers from the neck not to 

 tear the skin of that region.) 



II. The Abdominal Yiscera. 



Make a median longitudinal cut through the 

 skin on the ventral surface of the body and 

 neck, being careful not to cut deeper. 



Turn back the skin, and keeping it moist, note : 



1. The oesophagus and crop. 



2. The trachea.
