While ordinarily we do not favor the giving of injections or enemas unless they are absolutely necessary, we apply them freely in feverish diseases in order to remove from the rectum and lower colon any accumulations of morbid matter, and thus to prevent their reabsorption into the system. In cases of exceptionally stubborn constipation, an injection of a few ounces of warm olive oil may be given. Allow this to remain in the colon about thirty minutes in order to soften the contents of the rectum, and follow with an injection of warm water.
