The (Esophagus, 5, c, d, c, /, g, A, is six and a half inches long, narrow, and having a distinct muscular coat composed of trans- verse or circular fibres, with an internal mucous coat, studded with glandules or crypts, which pour out the clammy fluid with which it is constantly moistened. On the lower part of the neck,- it is expanded, or opens into a large membrane- ous sac, of a roundish form, the crop, d, e. On entering the thorax, at /, it is narrowed ; biit at g appears enlarged, which, however, is owing solely to the thick- ness of its walls there. This part, named the proventriciduSf has, between the outer musculsr and inner mucous coat, a great number of oblong hollow glandules, that secrete a peculiar fluid, which is copiously poured out into the cavity of the organ. Here the (Esophagus terminates, and is succeeded by the stomach or gizzard, A, f, j, k. This organ is of a roundish or somewhat rhomboidal, lobulated form. Its outer coat is composed of two very powerful lateral muscles, i, jy of which the fibres con- verge, become tendinous, and are inserted into a roundish tendinous space on each side; of a lower mu^icle, k, of the same nature, but less poweiful; and of a belt of superior transverse fibres, h. Within this muscular coat is another, of a dense tex- ture, thin, and having a semicartilaginous appearance. The inner coat is a very rous;h, hard, rugous sac, of which the portions opposite the two lateral muscles, z. j, are thicker and harder than the rest. The intestine comes ofit on the right side at /, forms a curve, ?, 7?i, which returns upon itself, m, n, enclosing the pancreas, and receiving its ducts, together with those bringing the bile from the liver and gall-bladder. The intestine, n, o, p, is then convoluted in the abdomen, and before terminating at (/, sends orF two
