11. That it checks the progress of putrefaction.
12. That it acts as a solvent of food, and alters its properties.
13. That, like other chemical agents, it commences its action on food as soon as it comes in contact with it.
14. That it is capable of combining with a certain and fixed quantity of food, and when more aliment is presented for its action than it will dissolve, disturbance of the stomach, or “indigestion,” will ensue.
15. That its action is facilitated by the warmth and motions of the stomach.
16. That it becomes intimately mixed and blended with the ingestæ in the stomach by the motions of that organ.
17. That it is invariably the same substance, modified only by admixture with other fluids.
18. That the motions of the stomach produce a constant churning of its contents, and admixture of food and gastric juice.
19. That these motions are in two directions, transversely and longitudinally.
20. That no other fluid produces the same effect on food that gastric juice does; and that it is the only solvent of aliment.
