_The Mustard Pack._—The child is stripped and laid upon a blanket, and the trunk is surrounded by a large towel or sheet saturated with mustard water. This is made as follows: 1 tablespoonful of mustard, 1 quart of water. In this the towel is dipped and, while dripping, wound around the entire body. The patient should then be rolled in the blanket. This pack may be continued for 10 or 15 minutes; at the end of which time there will usually be a very decided redness of the whole body. It may be repeated, according to indications. Where it is desired to produce general counterirritation, the mustard pack is not quite as efficient as the mustard bath, but it has the advantage in causing much less disturbance to the patient. The mustard pack is useful in the conditions of collapse, or of great prostration from any cause whatever, in convulsions, and in cerebral or pulmonary congestion. The degree to which the counterirritant of the skin should be carried will depend upon the condition of the pulse and the cyanosis. The feet may be placed in mustard water while the child lies in its crib (Holt). A FEW NOTES ON MEDICAL DISEASES. RHEUMATISM. A constitutional disease, characterized by fever, inflammation in and around the joints, occurring in succession, and a great tendency to induce the condition of endocarditis or pericarditis. =Cause.=—Usually exposure to cold—chilling of the body—damp atmosphere. =Treatment.=—Rest in bed is important. The bedding should be yielding, and the patient wear loose flannel night-clothes. Sleeping between blankets promotes perspiration, increases the activity of the skin, prevents exposure to cold and may reduce the liability to heart trouble. Change bed-clothing frequently. _Diet._—Should be easily digested food. Milk is the most suitable. Dilute with alkaline or mineral water. Barley- or oatmeal-water and lemonade may be given. Broths and soups may be substituted for milk at times. Regular feedings every two hours until patient convalesces. GOUT. Gout is characterized by sudden attacks of severe pain in the smaller joints, especially that of the big toe. There is a gradual deposit of urate of sodium in and about the joints, and presence of uric acid in the blood. =Causes.=—Intemperate living, excess in drinking wines and liquors, overindulgence in rich foods, change of climate. =Treatment.=—Proper elimination. Free use of all kinds of mineral waters, abstention from alcoholic drinks and moderation in eating. Exercise by walking and living in the open air may counteract any hereditary tendency to the disease. Cold baths, followed by massage, may be given to the sthenic patient, while the warm and tepid bath should be substituted for the asthenic type. Protect the body from exposure to cold. Flannel underwear should be worn.
