    mucosa and its greater consistency, no remarkable differences have been detected. The mucus in colica mucosa gives all the ordinary chemical reactions; among these reactions I mention in particular the pretty color test that A. Schmidt was the first to de- scribe and that Pariser later recommended again; this test is particularly applicable for the purposes of demonstration and is carried out as fol- lows : a small particle of mucus about as large as a pea, is placed in a test tube; the tube is then filled with about lo ccm. of a 5% solution of cor- rosive sublimate in alcohol; the tube is then vigor- ously shaken and the disintegration of the flake of mucus brought about in this way. After the sedi- ment has been allowed to settle at the bottom of the tube the alcohol is poured off and replaced by IOC cm. of distilled water. Then 3 drops of a 3% solution of Biondi’s staining powder (Farbstoffpul- ver) and a few drops of Ehrlich’s triacid mixture are added; the tube is again shaken and the flake of mucus again allowed to settle at the bottom; the staining fluid is then poured off and the flake of mucus washed several times with distilled water. The mucus will show a green or a dirty greenish- violet color whereas all albuminoid bodies turn a brilliant brick-red with this reaction.
