The fourth day, the rash having disappeared, and the heat being down to 98, whilst the pulse continued weak and quick, and the patient still had some delirium, I gave her a pack in the forenoon, without a bath previous, of an hour and a half, and a short bath after it; and in the afternoon, the patient having more delirium, the half-bath of 70 deg. was repeated, and the patient kept in it for twenty minutes. On the fifth day the ulcerating gland burst outside and the parotid gland became relieved. Pack and baths as the day before. In the evening the patient complaining of pain in the bowels, a sitz-bath of 70 deg. for twenty minutes was administered, and an injection after it, which relieved her. The rest of the time, one pack and bath in the morning, and a bath in the afternoon were deemed sufficient. On the eighteenth day of my treatment the patient left the house for the first time, and continued improving from day to day, the packs being continued for about two weeks longer on account of the broken gland, which continued to discharge. I tried to persuade the parents to continue the packs till the gland was healed, but they found it too much trouble. The patient drank a good deal of water during the whole of the treatment, ate very little and only light food, principally water-soup or panada, and gruel, and kept in bed almost entirely the first ten or twelve days. Her deceased little brother had the same symptoms, and I am confident, she would have followed him, had she not come under hydriatic treatment. 111. A later case, to which I have alluded before, was the following: The driver of a lady, who was under my care in Florence, attending to one of the lady's maids, who was sick with typhoid scarlatina, was taken ill. Like most uneducated people, he could not understand how water could do any good for diseases, and went to the village-store to buy some patent medicine, which he took. The remedy producing no good effect, he bought some other medicine--purgative pills, as I understood--and took it. Some friends of the village, which, like other villages, especially in America, was full of doctors--brought him nostrums and popular remedies, which he took for some days, till he could not leave the bed any more, delirium set in, and I was at last applied for. I found him with all the symptoms of typhus, and scarcely any of scarlatina, except the tongue, which seemed to struggle between a typhoid and scarlatinous appearance, but soon took all the form and color of the former. There was no rash, not much of a sore-throat, but constant delirium and rapid sinking of the strength of the patient.
