Cholera stools may be disinfected by adding a five per cent. cresol solution to them and allowing it to remain in contact with the stool for at least one hour. Quicklime is excellent as a disinfectant. Add together equal parts of fresh quicklime and water, dilute with three times as much water as previously used, add a quantity of this slaked lime equal to the amount of stool to be disinfected and allow it to remain in contact with the stool for one hour. When the ground has been fouled by dejecta or vomit, disinfect with cresol, or rake hot ashes over it or pour kerosene oil upon it and set the latter alight. Cholera-soiled clothing, bed linen and blankets should be soaked in a two and a half per cent. cresol solution. _Treatment._—Isolate the patient, keep him warm, and give ice to suck. Apply hot bottle to the feet, and mustard leaves to the pit of the stomach. It is advisable to clear the bowel of irritating material at the outset by giving half an ounce of castor oil with a teaspoonful of brandy. Drugs are of little use in cholera, but some like to give one drop of carbolic acid, together with twenty drops of spirit of camphor (or peppermint, or a little brandy), five grains of bismuth, and ten grains of soda, suspended in one ounce of gum water, every four hours. Chlorodyne may be given to allay severe pain. Even in the mildest cases absolute rest in bed is essential, and a warm bed-pan should be provided. In the early stages no food at all should be given, but plenty of fluid should be allowed, though it must be administered only in sips. Stimulants may be necessary. Later on fluid food such as milk should be given carefully, and the quantity gradually increased. The special treatment for cholera can only be carried out by a medical man, and recourse should be had to his help at the earliest possible moment, as everything depends upon immediate treatment. If, after the acute symptoms subside, diarrhœa continues a dose of bismuth is often useful. _Colic._ This is the name given to the well-known severe twisting or griping pains in the belly, usually due to excessive flatulence, and resulting from constipation, or some error of diet. _Treatment._—Hot fomentations should be applied to the belly, or better still, the Instra, which is the best means of applying continuous heat to any part of the body. A turpentine enema (a tablespoonful to a pint of warm water) will nearly always cut short the symptoms; in the absence of turpentine, give warm water alone. A full dose of opium (20 minims) should also be given if the pain is severe, preferably in a tablespoonful of castor oil. Bicarbonate of soda, carbonate of ammonia and ginger should be freely given in full doses, and the bowels should be well opened as soon as the severe pain has passed off. _Concussion of the Brain._ This term is applied to the partial suspension of the functions of the brain, produced by the severe shaking of its substance by a fall or blow.
