Rest is certainly an important adjuvant in the treatment of this form of malarial disease. I have known a recurrence to take place after a long drive. It is claimed for many natural mineral waters that hemorrhage from the kidneys is one of the affections cured by their use. Chalybeate and alum springs might be expected to be of advantage by the local action of these astringents in their transit through the kidneys, and they frequently are. The following case illustrates their efficiency: The patient was a lawyer who consulted me in June, 1881, at the suggestion of W. W. Covington of North Carolina. He had frequently had chills, and a congestive chill in 1873. Three months before I saw him he began to pass bloody urine. He had no other symptoms, except a soreness and weakness in the neighborhood of the sacrum, extending into the outer part of the left thigh. The urine passed for me at the time of his visit was dark reddish-brown in color, acid in reaction, had a specific gravity of 1028, highly albuminous, and deposited a sediment of almost tarry consistence, which was made up almost entirely of blood-corpuscles. There were no tube-casts. He had been a dyspeptic since seventeen years of age, and medicines disagreed with him; but he was treated faithfully with quinine, iron, arsenic, ergot, benzoate of lime, all without the slightest effect. At the end of about a year from the time he consulted me he heard of the Jackson Spring, located in Moore county, North Carolina, fifteen miles distant from Manly Station on the Raleigh and Augusta Railroad. He went there, and remained one week. He stated that for the first two or three days the water acted decidedly on his kidneys, and he voided a number of clots of blood. On the third day all traces of blood disappeared, and it recurred but once since, on a very cold day in November last, but again disappeared after a day or two in the house. Unfortunately, no precise analysis of this water seems to have been made, but {112} from what my friend writes it evidently contains iron and sulphur, and magnesia is also said to be present. It is promptly diuretic. Since this occurred I have used the water of alum springs in other instances with advantage.[13] [Footnote 13: See the report of a case treated successfully by Rockbridge alum-water by Radcliffe, _Med. News_, Jan. 12, 1884.]
