![mixed with meat, however, a very rapid development takes place, accompanied by a production of gas. According to these experiments, a diet for stomach-ailing patients, which should be followed by no production of gas, dis- tention of the stomach, sour eructation, etc., may consist of meat, eggs, fish, spinach, fresh lettuce, and small quantities of endives and sour cranberries. The administration of an antiseptic before, and a dio-estive during or immediately after the meal, will materially aid the process of digestion. I have had abundant opportunity to observe the happy action of the above diet on one who has for years been troubled with indigestion arising from abnormal fermentation in the stomach. 'o 31orp]<olo<jii. Bacterium aerogenes I. Short rods, single or in pairs, motile; forms on gelatine-plates circular yellowish colonies with distinct outlines. The colony is traversed by dark lines which often radiate from the center and extend close to its margin; it grows rapidly in line-cultures along the whole line with brown-yellow color, and forms a flat grayish-white pappy button; it does not liquefy the gelatine. On agar-agar it forms a grayish-white soft growth with indented irregular margin; grows rather rapidly. In line- cultures it grows as a cream-colored, moist deposit with smooth outlines, and shows under the microscope dark lines, which frequently run from the center to the margin. G-rowth without access of air somewhat retarded, but numerous gas-bubbles formed under the mica-plate. 3Iici'ococc>is aerogenes. Large oval cocci or plump rods, im- motile; forms quick-growing, mostly round, but occasionally somewhat indented colonies of dark color, with smooth contour. It is characterized by leprous spots, which are dark or bright according to the adjustment of the microscope; grows in line- cultures like Bacterium aerogenes, but somewhat faster; in old cultures slightly liquefying. Line-cultures are distinguishable by the naked eye from Bacterium aerogenes I by the more undu- lating course of the borders ; under the microscope the dark rays](https://iiif.wellcomecollection.org/image/b2120293x_0345.jp2/full/800%2C/0/default.jpg)
