To remove these symptoms, I gave the tincture of bark and elixir of vitriol in frequent doses. I likewise recommended the plentiful use of ripe fruits; but I saw the best effects from temperate meals of oysters, and a liberal use of porter. To these was added, gentle exercise in the open air, which gradually completed the cure. AN ACCOUNT OF THE _SCARLATINA ANGINOSA_, AS IT APPEARED IN PHILADELPHIA, IN THE YEARS 1783 AND 1784. The beginning of the month of July was unusually cool; insomuch that the mercury in Fahrenheit's thermometer stood at 61° in the day time, and fires were very comfortable, especially in the evening. In the last week but one of this month, the weather suddenly became so warm, that the mercury rose to 94-1/2°, at which it remained for three days. As this heat was accompanied by no breeze from any quarter, the sense of it was extremely distressing to many people. Upwards of twenty persons died in the course of those three days, from the excess of the heat, and from drinking cold water. Three old people died suddenly within this space of time. This extreme heat was succeeded by cool weather, the mercury having fallen to 60°, and the month closed with producing a few intermitting and remitting fevers, together with several cases of inflammatory angina. The weather in the month of August was extremely variable. The mercury, after standing for several days at 92°, suddenly fell so low, as not only to render fires necessary, but in many places to produce frost. Every form of fever made its appearance in this month. The synocha was so acute, in several cases, as to require from three to four bleedings. The remitting fever was accompanied by an uncommon degree of nausea and faintness. Several people died, after a few days' illness, of the malignant bilious fever, or typhus gravior, of Dr. Cullen. The intermittents had nothing peculiar in them, in their symptoms or method of cure. Towards the close of the month, the scarlatina anginosa made its appearance, chiefly among children.
