In the majority of Mammals, the stomach is a muscular bag of an irregular oval shape, lying obliquely across the abdomen. In the Flesh-eaters, whose food is easy of solu- tion, the stomach is usually simple, and lies nearly in the course of the alimentary ca- nal ; but in pro])ortion as the food departs more wide- ly in its composition from the body itself, and is there- fore more difhcnlt to digest, we find the stomach increas- ing in size and complexity, and turned aside from the general course of the canal, so as to retain the food a longer ; The inlet, or opening, into the cesophagus is called cardiac; the outlet,.
