We sometimes see relief given by the use of the warm bath, in cases of obstinate pain. The bath is more effectual, if warm wine is used, instead of water. I have had but few opportunities of trying the effects of cold water applied to the body in this disease; but from the benefit which attended its use in the cases in which it was prescribed, I am disposed to believe that it would do great service, could we overcome the prejudices which subsist in the minds of parents against it. After all that has been said in favour of the remedies that have been mentioned, I am sorry to add, that I have very often seen them all administered without effect. My principal dependence, therefore, for many years, has been placed upon VII. Country air. Out of many hundred children whom I have sent into the country, in every stage of this disease, I have lost but three; two of whom were sent, contrary to my advice, into that unhealthy part of the neighbourhood of Philadelphia called the _Neck_, which lies between the city and the conflux of the rivers Delaware and Schuylkill. I have seen one cure performed by this remedy, after convulsions had taken place. To derive the utmost benefit from the country air, children should be carried out on horseback, or in a carriage, every day; and they should be exposed to the open air as much as possible in fair weather, in the day time. Where the convenience of the constant benefit of country air cannot be obtained, I have seen evident advantages from taking children out of the city once or twice a day. It is extremely agreeable to see the little sufferers revive as soon as they escape from the city air, and inspire the pure air of the country. I shall conclude this inquiry, by recommending the following methods of preventing this disease, all of which have been found by experience to be useful. 1. The daily use of the cold bath. 2. A faithful and attentive accommodation of the dresses of children, to the state and changes of the air. 3. A moderate quantity of salted meat taken occasionally in those months in which this disease usually prevails. It is perhaps in part from the daily use of salted meat in diet, that the children of country people escape this disease. 4. The use of sound old wine in the summer months. From a tea-spoon-full, to half a wine glass full, according to the age of the child, may be given every day. It is remarkable, that the children of persons in easy circumstances, who sip occasionally with their parents the remains of a glass of wine after dinner, are much less subject to this disease, than the children of poor people, who are without the benefit of that article of diet. 5. Cleanliness, both with respect to the skin and clothing of children. Perhaps the neglect of this direction may be another reason why the children of the poor, are most subject to this disease.
