    when the inflammatory redness has reached only to vascular arborisations not very fine, it may disappear upon death; but if it has gone beyond this point, it remains. He also infers that the vessels of mucous membranes will not admit an in- jection when they are in a state of inflammatory congestion. The tumefaction of inflamed mucous membranes is varia- ble according to their situation, and some peculiarities of structure; and also according to the duration of the malady with which they are affected. It is less considerable than that of cellular tissue under equal circumstances, but exceeds that of other tissues excepting the skin. This thickening appears simultaneously with the redness, or a little before it, and keeps pace with it, augmenting continually until the red- ness is at its highest degree. Such as are most vascular and have the most loose cellular substance below them, and such as have the greatest number of muciparous glands and follicles in or beneath them, tumefy the most. The obstruction to res- piration and swallowing, in the phlegmasise of the pharynx and larynx exemplify this. Their surface, and especially when covered with papillae, becomes rough to a slight degree: the papillaj or villi tu- mefy also, and erect themselves so as to give a chapped or fissured appearance to the interstices between them, but they collapse upon death. The texture of an inflamed mucous membrane, besides the tumefaction, is augmented in its density so that it tears or resists force more strongly than natural, while the inflamma- tion is evolving and progressing: but, when the latter recedes and the membrane becomes infdtrated with muco-purulent matter, it becomes much softer than what it is in the nor- mal state; and is sometimes so pulpy and disorganized that the slightest handling,or even sweeping the fingerover it will tear it up, from its attachment to the subjacent cellular coat. This softened state, (ramollissement,) though common to all mu- cous membranes, occurs more frequently in the stomach and bladderj at least, in my proper experience, I have met with
