two inches. The pharynx is two inches wide. The 

 cesophag-us, which is nine and a half inches long-, is, 

 vaguely speaking, nearly uniform in diameter, and in- 

 stead of being dilated anterior to the furcula, as in 

 the eagles and hawks, is narrowest there. At its 

 lower part it gradually enlarges to form the proventri- 

 culus, which is completely encircled by roundish glan- 

 dules. The outer coat of the oesophagus is obscurely 

 fibrous, the inner smooth^with longitudinal rugae when 

 not dilated. From the pharynx, the cESophagus con- 

 tracts to a diameter of one inch and one-twelfth ante- 

 rior to the furcula ; the diameter of the proventriculus 

 is one inch and five-twelfths. It opens widely into the 

 stomach, so as to seem a part of it as much as of the 

 oesophagus. The stomach is a large broadly elliptical, 

 somewhat compressed bag, its largest diameter three and 

 a half inches, its breadth two and a half. Its outer coat 

 is composed of distinct fasciculated fibres, about half a 

 twelfth in diameter, and separated by spaces of the 

 same breadth. One of its tendons is nine-twelfths, the 

 other ten-twelfths in diameter. The inner coat is 

 smooth and even. The pylorus is nearly half an inch 

 distant from the edge of the cardiac orifice. At the 

 commencement, the intestine has a diameter of only 

 two-twelfths, but it suddenly enlarges to nine-twelfths, 

 and so continues to the entrance of the biliary and pan- 

 creatic ducts, at the distance of twelve inches from the 

 pylorus; it then gradually diminishes to near the coeca, 

 where its smallest diameter is four-twelfths. The ccb- 

 ca come oflF, one a little below the other, and are of the 

 usual form in this genus, cylindrical for about half their 

 length, then much enlarged, and at the extremity round-
