is continued, but not completed till long after being subjected to the action of the bile and pancreatic juice, and passing through the remainder of the small intestine. It is owing, he adds, to this speedy evacuation of the stomach, that the horse is less inclined to drowsiness, and less incommoded by active exercise, soon after meals, than almost any other animal. The late Baron Dupuytren had several opportunities of observing something analogous to this in the human subject. He had, at various times, under his care, patients in whom an opening into the intestine had taken place at different distances from the stomach, and through which the intestinal contents readily escaped. On giving several kinds of food at one meal, he remarked that they presented themselves at the wound in the _inverse_ order of their digestibility. Thus, fresh vegetables always made their appearance first, still retaining much of their peculiar structure; while animal substances either did not appear at all, or were so much altered in appearance as scarcely to be recognised. In the natural evacuations, however, the vegetable structure was generally imperceptible; so that a considerable change must have taken place on it as it advanced through the bowels, after passing the seat of the wound. Londe had occasion to remark the same thing in a lady in whom an opening into the intestine existed. When she ate cutlets or chicken, digestion was so far advanced before they reached the opening that their identity could not be recognised. But when she ate spinage, carrots, or vegetable soups, these articles arrived at the orifice scarcely at all changed. In this patient also, vegetable substances passed rapidly out of the stomach. Thus salads, prunes, apples, and spinage made their appearance at the opening in about an hour; while the remains of animal food never appeared in less than three hours. Londe indeed lays it down as a principle, that where the wants of the system are not great, the digestion or alteration of innutritious substances, such as stewed or raw fruits, carrots, &c., “begins only in the ileum.” He adds, that he “has always seen these substances resist the action of the acid and mucous juices of the stomach, as well as that of the pancreatic and biliary secretions.”[35]
