1. Bleeding, from four to sixty ounces, according to the age of the patient, and the state of the pulse. This remedy relieved the cough, eased the pains in the head, and in one case produced, when used a third time, an immediate eruption of the measles. 2. Lenient purges. 3. Demulcent drinks. 4. Opiates at night. 5. Blisters. And, 6. Astringent medicines, where a diarrh[oe]a took place. I saw evident advantages from advising a vegetable diet to many children, as soon as any one of the families to which they belonged were attacked by the measles. I lost but one patient in this disease, and that was a child in convulsions. I ascribed my success to bleeding more generally and more copiously than I had been accustomed to do, in the measles of former years. AN ACCOUNT OF THE _BILIOUS YELLOW FEVER_, AS IT APPEARED IN PHILADELPHIA, IN THE YEAR 1802. The weather during the month of January was unusually moderate and pleasant. In the latter end of it, many shrubs put forth leaves and blossomed. I saw a leaf of the honeysuckle, which was more than an inch in length, and above half an inch in breadth. There was but one fall of snow, and that a light one, during the whole month. The winds blew chiefly from the south-west in February. There was a light fall of snow on the 6th. A shad was caught in the Delaware, near the city, on the 17th. On the 18th and 19th of the month, the weather became suddenly very cold. On the 22d there was a snow storm, and on the 28th, rain and a general thaw. In March, the weather was wet, cold, and stormy, with the exception of a few pleasant days. The scarlatina anginosa and the cynanche trachealis were the principal diseases that prevailed during the three months that have been mentioned. In April, there were several frosts, which destroyed the blossoms of the peach-trees. In May, the weather was so cool as to make fires agreeable to the last day of the month. The wind blew chiefly, during the whole of it, from the north-east. The scarlatina continued to be the reigning disease. I saw one fatal case of it, in which a redness only, without any ulcers or sloughs, appeared in the throat; and I attended another, in which a total immobility in the limbs was substituted by nature for the pain and swellings in those parts which generally attend the disease. There were three distinct grades of this epidemic. It was attended with such inflammatory or malignant symptoms, in some instances, as to require two or three bleedings; in others it appeared with a typhoid pulse, which yielded to emetics: turbith mineral was preferred for this purpose; while a redness, without a fever, which yielded to a single purge, was the only symptom of it in many people.
