    in our knowledge of them, since most of the fungi which produce the butyric acid fermentation are anserobic, and consequently difficult to cultivate in a pure form. The best known and most studied of these micro-organisms is the one described by Prazmowski. It forms rods of 2 to 12 /X in length, which grow either singly or in a long series. Sometimes they assume a zoogloea form. When in the spore-bearing condition the organisms become of ellipsoid shape. The access of air will at once arrest its growth. This butyric acid fungus gives a characteristic reaction with iodine. We also find acetic acid and yeast ferments in the stomach. The food having undergone digestion in the stomach is called chyme, and passes through the pylorus into The Small Intestine. This chyme will consist of the following constituents : 1. Products of complete digestion in the mouth and stomach, viz., albumoses, peptone, changed gelatin, dex- trose, and laevulose. 2. Substances partially digested, that is to say, dis- solved, but not yet converted into peptone. In this group we shall find starch, dissolved gelatin, albumin, and the isolated, partially digested, primitive muscular bundles. 3. Matters quite unchanged by saliva and gastric juice such as cellulose, fats, and fatty acids. 4. Fluids which have not been absorbed in the stomach. 5. Saliva, gastric juice, and mucus. When the mixture has passed into the duodenum it will come in contact with the pancreatic juice, the bile, and the intestinal juice. These are alkaUne, and can only act in the presence of an alkali. The chyme as it leaves the stomach has a strongly acid reaction, but becomes alkaline by the time it has reached the lower part of the small intestine. 2
