days in the stomach. Theycan generally be recognized with the naked eye. The following are the elements recognized with the microscope: 1. Muscular fibers in various stages of digestion. 2. Vegetable parenchyma, 3. Amylum grains, 4. Fat-globules. 5. Mucous shreds. 6. Leucocytes more or less dissolved by the gastric juice. Theirnuclei are sometimes alone visible. They originate either from theinflamed mucous membrane of the stomach or from the saliva. 7. Red blood-corpuscles. They can be readily recognized ifthey have sojourned but a short time in the stomach, but soon thehsemoglobin is disintegrated, and its result, the hsematin, colors thecontents dark brown (coffee-ground vomiting in cancer of stom-ach). The hsemin reaction is then necessary to establish the pres-ence of blood. (See text to Plate 3.) VEGETABLE PARASITES LN THE STOMACH. We find, especially in dilatation, when the food has tarriedlonger than usual, a large number of vegetable parasites. Amongthem are mainly: PLATE 86

It closely resembles the sarcina nrinse,is only somewhat larger; when it occurs in greater numbers it maybe demonstrated in the stool. 3. Yeast fungi, Torula cerevisice, are cells, either round or oval,single or adherent, of different sizes. They multiply by budding—i. e., they produce a small bud, which, after growing to a certainsize, is abscinded. We have to guard against mistaking them forleucocytes or fat-globules. AISTMAL PARASITES OF THE STOMACH occur there only accidentally, and mainly originate from thebowel. Ascaris is not very rare in the vomit, more so oxyuris,and still less frequent trichina and echinococcus, Echinococcus is the cystic embryo of a diminutive tapeworm,at most five millimetres long, the Tmiia echinococcus of the dog.These embryos, which are the result of sexual generation b
