nervous layer beneath it is minutely and regularly scrobiculate. All 

 these circumstances might induce us to believe that the hair actually 

 grew in the substance of the epithelium ; but the presence of small 

 feathers and portions of feathers, similarly inserted, shews that they 

 are merely adventitious. The duodenum, Fig. 2, first curves on the left 

 side in the usual manner, but before ascending towards the liver, first 

 nearly forms a circle, then bends upon itself, and curves in the opposite 

 direction, as in the Caracara and White-headed Eagles. Its entire 

 length to the liver is 14 inches. The intestine is 5 feet 11 inches 

 long, its diameter from 5 twelfths to 3 twelfths ; the greatest diameter 

 of the rectum 8 twelfths, that of the cloaca 1 inch 2 twelfths. There 

 are no traces of coeca. 



The heart is 1 inch 10 twelfths long, 1 inch 8 twelfths broad. 

 The lobes of the liver are nearly equal, being about 1 inch 1 twelfth 

 long. 



The accompanying sketch, Fig. 4, represents a vertical section of 

 the head in the median plane, with the septum between the eyes and 

 that of the nasal cavities removed, so as to expose the left cavity, with 

 its turbinated bodies. The brain is marked a 6, the nasal cavity cde, 

 d being the upper, e the lower turbinated bone. Before and beneath 

 the latter is seen the passage to the posterior nares or palatal aperture 

 of the nose. The external nostril, or large opening which runs across 

 the bill, is marked h. From h to g are the large cells in the interior of 

 the upper mandible. Below y are the tongue and the lower jaw in out- 

 line. The bottom of the left eye is marked/!
