markable on the Inside of the Stomach and Intestines, because of the immediate Contact it has with those Parts.
All other Poisons which occasion Inflammations in the Stomach and Guts, do first operate upon the Blood-Vessels, and corrode the Parts inflamed. They occasion Vomitings and Fluxes of Blood, which at length terminate in Convulsions.
One may very easily be deceived upon opening the Stomach of a Dog, and may mistake the Redness of the Tunica Villosa for an Inflammation.
The inner' Coat of a Dog's Stomach is naturally of a ruddy Flesh-colour, and therefore of all domestick Animals a Dog has the quickest and strongest Digestion. Accordingly we see, that they swallow Bones, and digest them perfectly well; and although they are but half chewed when taken into the Stomach, yet they are at last reduced to as soft a Consistence as any other Part of their Aliment. It is for this Reason therefore, that the Stomachs of Dogs are more plentifully supplied with Blood than those of other Animals; by which Means not only the muscular Force of the Stomach, but its Warmth also, which is the principal Instrument of Digestion, is very much increased.
