_Prophylaxis._—Ensure a good dietary containing sufficient anti-scorbutic elements. Wherever possible, fresh meat, fresh vegetables, and fresh fruit should be supplied. Lemon juice is valuable. It should be noted that it is four times as efficient as the lime juice which used formerly to be employed. The ration should be one ounce daily served with sugar. Germinating peas, beans, and other pulses contain the anti-scorbutic elements in large quantity. It is a simple matter to carry a supply of these pulses and to germinate them when required. The dry seeds must be whole, retaining their original seed-coat. In order to make them germinate they are placed in a clean sack and steeped in a vessel containing clean water, which should be occasionally stirred. Sack and trough should be large enough to allow for the swelling of the pulses to about three times their original size. In a hot climate six to twelve hours is sufficient for this soaking. Thereafter, lift the seeds out of the water and spread them out to a depth not exceeding two or three inches in some vessel which allows free access of air to them. Keep them moist by covering with sacking, which is wetted at intervals. The germination should reach the stage necessary within twenty-four hours in a hot climate, and the pulses should be cooked and eaten as soon as possible after germination. Care should be taken not to overcook them. At a pinch germination may be effected by placing the seeds between wet blankets, but this is a rough-and-ready method not to be recommended. It is important to attend to oral hygiene, especially the regular use of the tooth-brush. Vegetables should never be overcooked. In the case of African native followers Kaffir beer made from germinated grain is of great value; one pint should be given daily per head. Potatoes and root vegetables are useful, and the onion is a valuable food in this connexion. Fresh meat is not so effective as either fresh fruit or vegetables. _Treatment._—This is chiefly dietetic, and the same foods and substances as are mentioned under prophylaxis are used also for the cure of scurvy. In addition, scurvy patients should be kept in bed, given plenty of fresh air, and have the affected parts massaged. Tonics and mouth-washes are indicated, and a liberal diet with plenty of fat in it should be provided. Where fresh fruit cannot be obtained raw meat and raw fresh eggs in milk form a good substitute. _Sea-Sickness._ Take a saline aperient on the day before embarking, and a light plain meal at least three hours before going on board. A cup of good tea or black coffee soon after starting is often of use. Those liable to sea-sickness should go to bed directly they get on board: the head should be kept low and the room darkened. A mustard leaf applied to the pit of the stomach is of value in diminishing the tendency to vomit. An abdominal belt is useful from the gentle support it gives. A hot-water bottle may be applied to the feet.
