oil, avoiding the sides, so that it floats separately, like the yolk of an egg surrounded by the white. If now the contents of the glass be swallowed as nearly as possible at a single gulp, the oil passes through the mouth and throat so completely surrounded by the spirit and water that its presence cannot be noticed. A tabloid containing ¹⁄₄₀ grain of perchloride of mercury should be taken shortly after, and after a lapse of three or four hours the disinfection of the contents of the intestine may be completed by taking a 10-grains tabloid of resorcin every four hours. As a rule, under this treatment the yellow colour soon reappears in the motions and all symptoms disappear; but should the liver refuse to act, as is indicated by the continued absence of the natural yellow colour in the motions, it will be necessary to give a large dose of ipecacuanha--to get this drug down without setting up vomiting, requires a certain amount of preparation--as in smaller doses, it is one of the safest and most certain of emetics. It is best to give the dose the last thing at night, when the patient is naturally likely to be sleepy, and half an hour before it is given, a preparatory dose of a grain of opium should be administered. The patient should lie as quietly as possible, and after the dose (30 grains, or half a dozen 5-grain tabloids of ipecacuanha) all liquids should be withheld. It is also important to use as little water as possible to wash down the tabloids, as success in keeping down the drug depends mainly on the absence of any notable amount of fluid from the stomach; and this abstinence from fluids, as well as from food, should be continued until the next morning, when in all probability a copious bile-stained motion will show that the drug has taken its desired effect. As a rule, after this, two or three tabloids, containing ¹⁄₄₀ of a grain of perchloride of mercury _per diem_, for a few days, will suffice to maintain the action of the liver and to disinfect the bowel, but occasionally the medication with ipecacuanha may have to be repeated. Remember, however, that no drugs will be of much service in this disease without the greatest care in diet.
