COMPLAIXTS OF THE DIGESTIVE TRACT. 317 ;

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.

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
it grows rapidly
from the center and extend close to its margin ;
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
