The chief seat of this terribly prevalent disease is in the stomach and intestines, particularly the colon. It is a foul, bacterial disease, and originates in filth. The germs may be taken into the system in impure water or milk, inhaling the gases from defective drains or by eating food which has absorbed such gases. Once in the system, the bacteria must have decayed matter to feed upon, therefore it is impossible for a person who is clean both inside and out to take typhoid fever, there being no facilities for the germs to breed and multiply. A peculiar secretion from the colon, mixed with the fæcal matter of long standing, induces a fermentation that generates a putrid smelling gas. This fermenting gas is the home of the bacillus, and from it millions of germs are multiplied and pass into the circulation. In this fermentation a peculiar worm is bred, which is the cause of ulceration in the bowels of typhoid patients. TREATMENT. To give physic in a typhoid fever case is a grave mistake. Instead of assisting Nature, it more probably hastens the death of the patient. Knowing the cause of the disease, common sense tells us that the first thing to do is to check the multiplication of the germs by removing the putrid matter in which they breed. When the symptoms first appear give the patient a warm water emetic. Drink until the stomach throws it back. Do not be afraid to drink. If the stomach is obstinate, use the index finger to excite vomiting. This washes out the contents of the stomach, which will be found fermenting and full of bacteria. Then give him a large cup of hot water--very hot--with a little salt in it. Let the patient rest for an hour or so after vomiting, then use the “Cascade” with water just as hot as the hand will bear, so it will not scald. Let him retain the water from ten to fifteen minutes if he can. Next, the patient must be sweated, to open up the pores of the skin, and for this nothing equals the wet sheet pack. Roll the patient in a sheet wrung out of cold water, on top of this a couple of blankets and a comfortable. At his feet place hot bricks in flannel, on his head a towel, wrung out of cold water. Give him plenty of fresh air. When he has perspired freely take him out of the pack, wash him with warm water, and soap, rub him down, give him a drink of cold water and put him to bed. Repeat the injections daily, using tepid water. In cases of extreme weakness the treatment must be modified. Let the patient have all the cold water he wants to drink and give him plenty of fresh air. Use flushings daily, also the external bath, remembering in the latter to use cold water when the fever is high, and he will speedily be restored to health. Let him eat nothing until Nature calls for it. The best test of hunger is a piece of stale dry Graham bread. BILIOUS FEVER.
