In Fig. 2. are represented :—the lower part of the cesophagus, d, ¢, 
J; the proventricular sac, /, g, 4; the very small gizzard, h; the duo-

the left side. 
Fig. 3. represents :—the proventricular sac thrust forward, /, g, 4; 
the gizzard, 4; the duodenum, 7%, j, #, pulled to the right side ; the con-
