Diseases of the digestive apparatus are discussed under the headings of difficulties of deglutition, canine appetite, bolismus (boulimia), disturbances of thirst, eructations, hiccup, nausea and anorexia, vomiting, anathimiasis (gastric debility), anatropha and catatropha (varieties of obstinate vomiting), pain in the stomach, abscess of the stomach, salivation, colic, dysentery and diarrhoea, intestinal worms, hemorrhoids, rectal tenesmus, prolapsus ani, fistula in ano, diseases of the liver, dropsy, jaundice and diseases of the spleen. Abscess of the stomach sometimes manifests a circumscribed tumor, and accordingly, probably includes cancer of that organ. Approved remedies are the Al'mirabile, the stomatichon frigidum, calidum or laxativumvum, etc., stereotyped formulae, of which the composition is carefully recorded. Dysentery is a flux of the bowels with a sanguinolent discharge and excoriation of the intestines. A variety called hepatic dysentery, however, lacks the intestinal excoriation. Diarrhoea is a simple flux of the bowels, without either the sanguinolent discharges or the intestinal excoriation. Lientery is a flux of the bowels with the discharge of undigested food, occasioned by irritability (_levitas_) of the stomach or intestines. Colical passion and iliac passion derive their names from the supposed origin of the pain in the colon or ileum, a remark which furnishes occasion for the statement that Gilbert divides the bowels into six sections, viz., the duodenum jejunum and ileum, and the orobus, colon and longaon (rectum). Intestinal worms are not generated in the stomach, as Gilbert says, because of the great heat produced by the process of digestion. In the intestines they originate chiefly from the varieties of phlegm, e.g., saline, sweet, acid, natural, etc. The species mentioned specifically are lumbrici and ascarides or cucubitini, though the terms long, round, short and broad are also employed, and probably include the tape worm or taenia lata. The treatment of these parasites consists generally in the use of aromatic, bitter or acid mixtures, among which gentian, serpentaria, tithymal and cucumis agrestis are especially commended for lumbrici, and enemata of wormwood, lupinus, scammony, salt, aloes, etc., for ascarides. The diseases of the liver, though not numerous, are allotted considerable space most of which is occupied by scholastic speculations and the usual rich supply of therapeutical suggestions. Discrasia of the liver has several varieties, warm, cold, moist and dry, and seems nearly equivalent to our somewhat overworked term of "biliousness." Gilbert's favorite compounds for the relief of this condition are the Trifera sarracenica, the Electuarium psilliticum and above all the Dyantos Besonis.
